▼ Clinical kinematic studies have been underutilized in veterinary medicine. Previous studies have focused on hindlimb joint motion with respect to flexion and extension utilizing a linear-link model to define sagittal plane motion; however, joint movement is complex and incompletely represented in a two-dimensional (2-D) model. While 2-D models provide accurate and repeatable information about uniplanar motion they are limited in their ability to assess true three-dimensional (3-D) joint motion. The Joint Coordinate System (JCS) was developed to describe 3-D joint motion by 6 independent coordinates or 6 degrees of freedom. Additionally, it facilitates the description and understanding of joint motion between biomechanical and clinical fields. The benefit of a segmental rigid-body model, such as the JCS, is that it provides an anatomically accurate and clinically relevant 3-D description of joint motion with six degrees of freedom.
These studies were performed to provide the initial description of a 3-D segmental rigid-body model of the hindlimb of the dog based on the JCS. Additionally, to compare this new 3-D model to previous 2-D models, and describe the effect of known sources of kinematic variability on this model. The results of the first study established that the new 3-D model produces similar sagittal plane
kinematics to previously established 2-D models; while providing additional information regarding the transverse and frontal planes of joint motion. The second study found that changes in marker placement alter kinematic data similarly for the 3-D and 2-D models. For both models, the greatest degree of change was found when placement errors occurred in the craniocaudal direction. The third study established that inter- and intra-examiner variability occurs with the 3-D model. Similar findings have been shown with 2D models. However, experience with the 3D model reduced overall variability and resulted in consistent and repeatable sagittal plane kinematic data collection. The final study evaluated the effect of different modes of ambulation (overground versus treadmill) on the 3-D kinematic model. We found that while both modes produce similar gait waveforms, only sagittal plane data was unaffected by mode of ambulation.

▼ Although the incidence of non-contact anterior cruciate ligament (ACL) injuries is greater among
women than men athletes, the factors that contribute to this greater risk of injury are not well
understood. One relevant question is whether decision making during landing influences the
biomechanical and neuromuscular factors thought to contribute to ACL injury, and whether these effects
differ as a function of task and sex. The purpose of this study was thus to examine the effects of decision
making on the neuromechanics of two-footed landing tasks in women and men.
Twenty-nine healthy young adults (13 women; 16 men) completed a series of two-footed drop
landing and drop-jump tasks under preplanned and decision-making conditions. Biomechanical and
electromyographic data were collected. Repeated measures ANOVA was used to determine the effect of
decision making on hip, knee, and ankle
kinematics and kinetics, and on proactive and reactive muscle
activity, as a function of task and sex. Multiple linear regression was used to assess the relationship
between select knee biomechanical variables and proactive muscle activity.
Decision making had numerous effects on lower extremity
kinematics, kinetics, and
neuromuscular control, many of which were task-specific. Under decision-making conditions, individuals
exhibited similar joint postures at initial ground contact and similar amounts of reactive muscle activity
across tasks. The majority of the observed modifications in neuromechanics suggested a default towards
the preplanned drop landing strategy under decision-making conditions. Some effects of decision making
on joint mechanics and reactive muscle activity varied with sex, although the extent to which these
dissimilar effects modified relative ACL loading is not known. Knee flexion at initial contact, peak knee
abduction, and peak knee adduction moment were significantly related to the proactive activity of
several, primarily lateral, muscles of the lower extremity, independent of task and decision-making
condition.
These results indicate that decision making influences landing mechanics and neuromuscular
control and that these effects are generally task-dependent and, in some cases, sex-dependent. The
results also suggest that, in both women and men, drop landings and drop-jumps performed under
decision-making conditions are no more dangerous, with respect to ACL loading, than preplanned drop
landings.

▼ M.S. University of Hawaii at Manoa 2013.
Purpose: Osteoarthritis is a prevalent hip disease primarily affecting older populations, causing pain, muscle weakness, contracture, and gait abnormalities. When conservative treatments have failed, total hip arthroplasty (THA) is often the prescribed treatment to correct osteoarthritic changes. Although THA can reduce pain and improve function, gait abnormalities persist long after surgery. Therefore, the purpose of this study was to evaluate the effects of THA on hip biomechanics, muscle torque, gait velocity, and pain in osteoarthritic hip patients preoperatively and postoperatively.
Methods: Biomechanical gait analysis was completed for 15 THA and 11 healthy control participants using a three-dimensional motion capture system. Gait, hip muscle torque, walking velocity, and pain data were collected during six sessions: preoperatively; and postoperatively, at three and six weeks, and at three and six months.
Results: Differences in hip extension angle, external hip extension moment, hip flexion, extension, and abduction torque, walking velocity, and pain were revealed between groups. The THA group demonstrated lower values and significantly higher improvements postoperatively than the experimental group. Initial decreases in hip flexor torque were observed within the first three weeks postoperatively. Six weeks postoperatively, a reduction in pain combined with increased extension angle contributed to improved muscle torque and gait characteristics.
Conclusions: Osteoarthritic hip patients demonstrated diminished gait characteristics and muscular torque when compared to controls. While these gait characteristics improved post operatively they did not return to control values with the exception of hip extension and abduction torque, walking velocity, and pain level at six months postoperatively.

▼ Compared with serial-structure-based manipulators, parallel manipulators have potential advantages in terms of stiffness, payload, etc. In certain applications that require less than six degrees of freedom (or lower mobility) task motions, parallel manipulators are especially more suited than their serial counterparts. In this dissertation, we study a new design method, called ”Integrated Design Method”, for the design of lower-mobility parallel manipulators. The design parameters of the integrated design method consist of both mechanical structure parameters such as link length, mass, mass center location, etc. and control parameters such as PID feedback gains. All these design parameters would be included in the kinematic and dynamic models of the selected parallel manipulator candidate. In addition to rigid body kinematics and dynamics, we also studied the kinematics and dynamics of lower-mobility parallel manipulators with flexible links/joints. With the derived model, several performance indexes, such as workspace, condition number, motion type error and lowest natural frequency of flexible parallel manipulators, were defined and formulated. Then, the design problem was translated into an optimization problem by proper combination of these performance indexes, and the two groups of design parameters could be obtained simultaneously. A planar parallel manipulator, named the HKUST Planar-Delta, was selected to validate the design theory. Mechanical parameters such as the link shape and controller parameters such as the PD feedback gains were chosen as the design variables. Kinematic and dynamic models considering link flexibility were derived and identified by simulations and experiments. With the design specification extracted from the positioning stage of LED wire bonding machines, a multi-objective optimization problem was formulated and solved. Finally from the experimental results, it can be concluded that using the integrated design method, the lowest natural frequency of the Planar-Delta was increased by 30% averagely while other requirements on the workspace and accuracy were all satisfied.

▼ In this thesis, a differential-geometric approach to the
kinematics of multibody mechanisms is introduced that enables analysis of singularities of both serial and parallel manipulators in a flexible and complete way. Existing approaches such as those of Gosselin and Angeles [1], Zlatanov et al. [2] and Park and Kim [3] make use of a combination of joint freedoms and constraints and so build in assumptions. In contrast, this new approach is solely constraint-based, avoiding some of the shortcomings of these earlier theories.
The proposed representation has two core ingredients. First, it avoids direct reference to the choice of inputs and their associated joint freedoms and instead focuses on a kinematic constraint map (KCM), defined by the constraints imposed by all joints and not requiring consideration of closure conditions arising from closed loops in the design. The KCM is expressed in terms of pose (i.e. position and orientation) variables, which are the coordinates of all the manipulator’s links with respect to a reference frame. The
kinematics of a given manipulator can be described by means of this representation, locally and globally. Also, for a family of manipulators defined by a specific architecture, the KCM will tell us how the choice of design parameters (e.g. link lengths) affects these kinematic properties within the family.
At a global level, the KCM determines a subset in the space of all pose variables, known as the configuration space (C-space) of the manipulator, whose topology may vary across the set of design parameters. The Jacobian (matrix of first-order partial derivatives) of the KCM may become singular at some specific choices of pose variables. These conditions express a subset called the singular set of the C-space. It is shown that if a family of manipulators, parametrised by a manifold Rd of design parameters, is “well-behaved” then the pose variables can be eliminated from the KCM equations together with the conditions for singularities, to give conditions in terms of design parameters, that define a hypersurface in Rd of manipulators in the class that exhibit C-space singularities. These are referred to as Grashof-type conditions, as they generalise classically known inequalities classifying planar 4-bar mechanisms due to Grashof [4].
Secondly, we develop the theory to incorporate actuator space (A-space) and workspace (W-space), based on a choice of actuated joints or inputs and on the manipulator’s end-effector workspace or outputs. This will facilitate us with a framework for analysing singularities for forward and inverse
kinematics via input and output mappings defined on the manipulator’s C-space. This provides new insight into the structure of the forward and inverse

Veterinary Medicine. Advisor: Stephanie J. Valberg. 1 computer file
(PDF); iv, 102 pages, appendices 1-2.
Pelvic limb movement disorders in horses are,
commonly, not well defined leading to confusion and inconsistencies
regarding their diagnoses. A standardized web-based survey (n=305)
was used to collect epidemiological data and videos. A standardized
video (n=70) was requested from owners. Literature review and video
analysis produced a definition of Shivers being hyper-flexion
(Shivers-HF n=21) or -extension (Shivers-HE n=6) of the pelvic
limbs during backwards walking and manual hoof lifting. Subjective
and kinematic video analysis provided differences between Shivers,
Stringhalt (n=7) and more advanced Shivers cases (Shivers-FHF n=4)
where hyperflexion during forwards walking was seen. For the
epidemiological survey diagnosis was confirmed either by video
submission [v+ n=27], or by reported clinical signs alone [v-
n=67]. Fifty matched case-controls were obtained. V+ had
significantly more WBs, TBs and Draft breeds, taller horses
(>17hh) and males compared to the controls. Height was the only
significant predictor variable however. Signs frequently began at
<10 yrs of age (V+ and V-). Both groups reported an improved
with increased turnout, exercise and a low carbohydrate diets. No
therapies were helpful or curative. More V+ horses showed
progression of signs signs over time (80+%) than v- horses
(50+%).

▼ In this paper we describe a novel technique for solving the inverse
kinematics problem for human fingers.
We derive a closed-form solution that places the fingertips precisely in the desired location by allowing minor deviations in the rotations of the Proximal Interphalangeal
and Distal Interphalangeal joints compared to the fixed ratio that is known to exist between them.
The obvious advantage is that with our approach there is no need to iterate until the distance between the fingertips and the desired locations is small enough.
We show that this method is reliable and exact while showing minimal differences to the finger poses generated by the original closed-form solution.
In our experiments we found the positions of the intermediate joints of the finger to deviate only around 1.5 mm in the worst case from those resulting from a numerical approximation of the original closed-form solution. On average the deviation is less than 0.5 millimeter.

▼ Origami provides novel approaches to the fabrication, assembly, and functionality of engineering structures in various fields such as aerospace, robotics, etc. With the increase in complexity of the geometry and materials for origami structures that provide engineering utility, computational models and design methods for such structures have become essential. Currently available models and design methods for origami structures are generally limited to the idealization of the folds as creases of zeroth-order geometric continuity. Such an idealization is not proper for origami structures having non-negligible thickness or maximum curvature at the folds restricted by material limitations. Thus, for general structures, creased folds of merely zeroth-order geometric continuity are not appropriate representations of structural response and a new approach is needed. The first contribution of this dissertation is a model for the
kinematics of origami structures having realistic folds of non-zero surface area and exhibiting higher-order geometric continuity, here termed smooth folds. The geometry of the smooth folds and the constraints on their associated kinematic variables are presented. A numerical implementation of the model allowing for kinematic simulation of structures having arbitrary fold patterns is also described. Examples illustrating the capability of the model to capture realistic structural folding response are provided. Subsequently, a method for solving the origami design problem of determining the geometry of a single planar sheet and its pattern of smooth folds that morphs into a given three-dimensional goal shape, discretized as a polygonal mesh, is presented. The design parameterization of the planar sheet and the constraints that allow for a valid pattern of smooth folds and approximation of the goal shape in a known folded configuration are presented. Various testing examples considering goal shapes of diverse geometries are provided. Afterwards, a model for the structural mechanics of origami continuum bodies with smooth folds is presented. Such a model entails the integration of the presented kinematic model and existing plate theories in order to obtain a structural representation for folds having non-zero thickness and comprised of arbitrary materials. The model is validated against finite element analysis. The last contribution addresses the design and analysis of active material-based self-folding structures that morph via simultaneous folding towards a given three-dimensional goal shape starting from a planar configuration. Implementation examples including shape memory alloy (SMA)-based self-folding structures are provided.

▼ Continuum manipulators have become prevalent in many minimally invasive surgeries; typically, these surgeries involve only soft tissues. The exponential growth of this field has resulted in a variety of manipulator designs and associated models to understand and control the manipulators. Many of the existing models rely on constant-curvature (or piecewise-constant) assumptions that are borne out in manipulators under study. However, such constant-curvature assumptions fail to accurately describe a single-body manipulator specifically designed for orthopaedic surgery. This planar, underactuated manipulator exhibits variable curvature bending and complex responses to environmental constraints. This work investigates the utility of such a manipulator for the treatment of osteolysis (bone degradation) occurring behind a total hip replacement by examining the workspace, inverse
kinematics, and control. Defining the manipulator workspace using convolution on group elements
shows the manipulator is capable of achieving over 95% coverage in an osteolytic lesion, compared to the nominal 50% reported by clinicians. Several inverse kinematic models are presented, including (a) constrained energy minimization using tip position (or position and orientation) feedback and (b) interpolation among discrete shape-sensing elements simulated along the manipulator length. These approaches are examined with and without external loads applied to the manipulator; the position and orientation constrained function offers the best results, but all achieve sub-millimeter accuracy on average. The research concludes with the design and implementation of an efficient, model-less controller using feedback from curvature sensors; the controller reliably predicts control inputs. While the motivating manipulator bends in a single plane, these methods may be extended to consider variable curvature manipulators capable of three-dimensional bending.

▼ Many authors have proposed that sprint and distance front crawl swimmers differ in their stroke characteristics, however little three-dimensional quantitative data is provided to support these assumptions. It is currently unknown whether sprint and distance swimmers exhibit distinct stroke characteristics when swimming at the same pace. There were two main purposes of this study: 1) to determine whether there are distinct kinematic and kinetic differences between sprint and distance front crawl swimmers, and 2) to investigate whether stroke characteristics of front crawl swimmers, in terms of kinematic and kinetic variables change with swimming speed. Fifteen male national/international front crawl swimmers (17.87 +/- 2.33yrs; 73.87 +/- 8.72kg; 183.02 +/- 6.84cm) volunteered to participate in this study. This sample was composed of seven sprint (SG) and eight distance (DG) swimmers. Each testing session required swimmers to perform four 25m sprints and one 400m max effort (front crawl), with no pacing strategy, in a randomised order. Each trial was performed through a 6.75m3 calibrated space and recorded by six gen-locked JVC KY32 CCD cameras (4 below and 2 above water) sampling at a frequency of 50 fields per second. All trials were processed using ‘APAS’ software to obtain 3D coordinate data. Anthropometric measures were quantified using the elliptical zone method. Both data sets were entered into a bespoke MATLAB program which output: average swim velocity (Vav), stroke length (SL), stroke frequency (SF), stroke index (SI), vertical and lateral displacement for each segment, shoulder and hip roll angle, and elbow joint angle variables (1st back, shoulder x, end back, hand exit and recovery elbow angle). Stroke phase (entry, pull, push and recovery) durations (%) were quantified at instants corresponding to percentiles of the stroke cycle. Centre of mass position data were obtained from the digitised 3D data using a 14 segment rigid link body model in conjunction with the body segment parameter data obtained by the elliptical zone method. Component whole body velocity (VCOMHor), acceleration (accCOM) and net force (forceCOM) were derived from the centre of mass position data. Variables were statistically analysed in SPSS v.14.0, using a General Linear Model, repeated measures analysis of variance. The results indicated that the groups differed (p<0.05) with respect to the duration of the pull phase, the occurrence of max left and right shoulder roll and the temporal sequencing of the shoulders and hips rolling at both sprint and distance pace. Other variables approached significance between the groups, particularly when distance swimming, such as the duration of the push phase (p=0.082), the Vav (p=0.071) and average VCOMHor (p=0.071). The stroke kinematic variables that changed between paces (p<0.05) were the duration of the entry, pull, push, hand exit and recovery phases; the elbow angle at the end back position and the push phase range; total shoulder and hip roll; the sum average vertical displacement of the…

▼ Background and significance: Users of manual wheelchairs have to perform many movements within the confines of the wheelchair as well as utilize the wheelchair as a means of locomotion, for transferring to adjacent seating, and performing weight relief lifts, among other activities. The shoulder does not normally function as a weight bearing joint; however, users of manual wheelchairs rely heavily on their shoulder joints for these activities and shoulder pain is prevalent. There is general consensus that reduced subacromial space caused by altered glenohumeral kinematic patterns during wheelchair activities exposes the soft tissues at the shoulder, primarily the rotator cuff tendons, to mechanical compression during movement. The purpose of this study was to model the potential impact of angular kinematics during activities of daily living (wheelchair propulsion, weight relief raises, and scapular plane abduction) on the underlying subacromial space and resulting proximity of anatomical structures in a population of manual wheelchair users with reported shoulder pain.
Research Methods: Fifteen spinal cord injured individuals participated in the study. The individuals used manual wheelchairs as their primary means of mobility and reported anterolateral shoulder joint pain presumed to be caused by mechanical impingement. The three-dimensional position and orientation of the subjects’ thorax, scapula, and humerus were collected using an electromagnetic tracking system during weight relief, propulsion, and scapular plane abduction. Scapulothoracic (3 rotations), glenohumeral (3 rotations) and thorax flexion/extension angles were determined throughout the tasks. Each subject’s glenohumeral rotation values were combined with CT-generated bone models of the scapula and humerus to simulate all three tasks. At each of the time steps, the proximity (distance) mapping and minimum distance from each of three tendon footprints (infraspinatus, supraspinatus, and subscapularis) to the acromion and coracoacromial ligament were determined.
Analysis: Between-task and within-task comparisons of the angular kinematics were performed using repeated-measures ANOVA. Between-task comparisons of the minimum distance were performed using repeated-measures ANOVA, while the proximity maps were qualitatively assessed. Sensitivity of the linear distance values to errors in kinematic values were computed as well as an exploratory regression to predict linear distances from glenohumeral kinematics.
Results: Significant between-task and within task differences were observed in many of the kinematic variables. The weight relief task possessed peak values for scapulothoracic internal rotation and anterior tilt, and glenohumeral internal rotation, and when comparing mean event data, it possessed greater anterior tilt (equal to propulsion) and glenohumeral internal rotation. Scapular plane abduction possessed the least at-risk kinematics, with the smallest event data across tasks for anterior tilt and glenohumeral internal rotation as well as for…

▼ Humans have a unique opposable thumb that maintains a
fine balance between mobility and stability to allow motions that
span from precision handling to power grasping. Much of the
versatility of the thumb is due to the saddle geometry of first
carpometacarpal (CMC) joint. Located at the base of the thumb, the
CMC joint is the most common site of reconstructive surgery in the
upper extremity. Nearly 40% of postmenopausal women are affected by
CMC osteoarthritis (OA)—a progressive degenerative disease of
articular cartilage, bone, and synovium that results in decreased
dexterity and partial impairment of the upper extremity. Although
current treatment options can alleviate pain, they cannot restore
the lost strength and mobility, or halt disease progression,
because the pathophysiology of the disease is poorly understood.
While both biological and mechanical factors are implicated in the
etiology of CMC OA, the synergistic mechanism of disease evolution
remains unclear, partially due to a paucity of published data on
CMC joint biomechanics in healthy and diseased populations.
Accordingly, the objective of this work was to study CMC joint
biomechanics using in vivo image-based techniques, and to determine
if there are any differences with sex, age, or OA onset that could
point to the etiology of the disease. 155 subjects—healthy men and
women of two age groups and patients with early stage CMC OA—were
recruited for the study. Sequential computed tomography scans of
the hands and wrists of all the participants were acquired while
they performed functional tasks and range-of-motion activities. The
imaging data were used to study joint motion, stability, contact
mechanics, articular shape and congruence, as well as to model soft
tissue: cartilage and ligaments. The findings presented here
suggest that there may not be a mechanical predisposition to CMC
OA, but that women may be more susceptible to cartilage loss due to
systemic changes with aging. In addition to channeling future
research in the right direction, the furthered understanding of CMC
joint biomechanics should serve to refine the current surgical
procedures and to inspire new conservative options for disease
treatment and prevention.

▼ Infants born preterm with very low birth weight are at
increased risk for developing spastic cerebral palsy, which is
characterized by walking limitations due to a reduced ability to
move the joints of the leg in an out-of-phase pattern; e.g.,
flexing the hip while extending the knee. In typical development,
the spontaneous kicks of newborn infants are dominated by an
in-phase coordination pattern of synchronous flexion or extension
of the hip, knee, and ankle joints. Within the first months of
life, infants demonstrate a greater variety of intralimb joint
coordination patterns which is thought to support the progress to
more functional coordination patterns of the lower extremities
necessary for independent mobility. PT infants also demonstrate
this developmental change from in-phase to a greater variety of
joint coordination patterns, however, some PT infants exhibit
prolonged in-phase joint coordination which places them at
increased risk of developing cerebral palsy. The purpose of this
dissertation is to gain a better understanding of the contribution
of torque changes to the early changes in leg joint coordination of
typically-developing full-term infants, clarify the differences
between leg joint coordinations and torques of preterm and
full-term infants, and determine whether preterm infants have the
potential for a greater amount of out-of-phase leg joint
coordination when interacting with an infant-activated mobile that
reinforces out-of-phase leg joint coordination. ❧ Three studies
were conducted to answer these questions. The first study
investigated the contribution of torque changes to the early
changes in leg joint coordination of typically-developing full-term
infants. We analyzed kicking actions within 10 full-term infants
and between 6 and 15-weeks of age using a three-dimensional
kinematics and kinetics approach. We found that although 73% of
joint angle pairs demonstrated a change from an in-phase intralimb
coordination pattern at 6-weeks to an increased variety of
intralimb joint coordination patterns at 15-weeks, there was not an
obvious developmental change in net joint torques or intersegmental
dynamics. Further analysis supported that a greater variety of
hip-knee joint coordinations from 6 to 15-weeks of age was
associated with a decreased influence of knee muscle torques which
allowed passive knee gravitational and motion dependent torques to
have a greater influence on the coordination of the kick,
contributing to a greater variety of hip-knee joint coordinations.
❧ The second study investigated the contribution of torque changes
to the early changes in leg joint coordination of preterm infants.
From 6 to 15 weeks, preterm infants demonstrated less in-phase
coordination in 30% of joint angle pairs, versus 73% of joint angle
pairs in full-term infants. At 6 weeks preterm infants as compared
to full-term infants demonstrated less in-phase coordination in 4
of 15 joint angle pairs, but this difference resolved at 15 weeks.
Similar to full-term infants, there was not an obvious

▼ Humans can perceive affordances–invariant combinations
of surface/substance properties of the environment taken with
reference to an animal–action capabilities that describe
possibilities for action–for themselves and others. For example, we
can perceive the affordance of reach-with-jump (RWJ)–the maximum
height one can reach overhead while jumping–for another person
without ever seeing the person jump. Accurate perception of
affordances for others requires perceptual information about the
other's capacity to produce force; after observing another's
walking patterns, observers improve in their perception of the
other's RWJ height, suggesting there is structure in a person's
walking
kinematics which is informative about his/her ability to
jump to reach an object.Athletes demonstrate a superior ability to
perceive the action capabilities of others; after basketball
players observe an actor's walking patterns, they improve in their
perception of RWJ for the actor more so than controls. This
implicates movement
kinematics as the fundamental information
provided by walking motion, and suggests basketball players are
more sensitive to the structure available in the
kinematics that
allows accurate affordance perception; however, the nature of this
structure remains unclear.

▼ A 35 degrees-of-freedom humanoid robot is constructed
in a modular fashion with repeated seven degrees of freedom serial
robot chain with spherical-revolute spherical joints for the trunk,
arms and legs. The major benefit of the repeated serial structure
is the ease of computations resulting from the similar kinematic
parameters for the five serial robot chains. Simulations are done
to test the behavior of the humanoid.The humanoid robot arm is
simulated using the resolved rate control motion, with a constant
velocity input for the hand. The inverse dynamics solution for the
resolved rate control motion of the humanoid arm is developed using
an iterative Newton-Euler formulation and the required actuator
torques are calculated. The humanoid robot is also simulated in the
context of resolved rate control, with motion constrained to the
left arm. The proposed humanoid robot is kinematically simulated
for walking and stair climbing with trajectory planning, from
literature, in the form of joint angles for each step of
locomotion.

▼ The Portable Biomechanical Assessment Suite (PBAS) is
a suite of sensors to measure the kinematics and kinetics of the
human body during lifting tasks. The suite is made up of ten
inertial measurement units (IMUs) and the Novel Pedar pressure
insoles. The IMUs are made up of an Xbee radio, a triple-axis
accelerometer, a dual-axis gyroscope, and a single-axis gyroscope.
The data are sent via the 802.15.4 wireless network protocol to a
collection device connected to a computer and are stored in a
binary data file that is then read and processed by a Matlab
program. The output of the program is four data matrices:
x-acceleration, y-acceleration, z-angular velocity, and the
calculated angular position of each IMU. The pressure insoles are
synchronized with the IMUs to measure the ground reaction forces.
An initial test was run to determine how battery life, the zero
voltage level, and dropout rate change with data transmission time.
The tests showed that the IMUs could easily run for five hours with
no effect on the dropout rate. The accelerometer was found to have
very little zero-drift while the gyroscopes do exhibit some zero
drift. This will need to be taken into account for long tests.
Three pendulum tests were run to test the IMUs, all yielding good
results. The first test used three preliminary IMUs made on
breadboards to validate the circuit design and general concept. The
next two tests used five final IMUs to measure the kinematics of
the pendulum. One test had all IMUs measuring in the sagittal plane
while the second test used three sagittal plane IMUs and two IMUs
reprogrammed to measure the corresponding signals in the coronal
plane. Both tests showed that the IMU signals matched what was
expected and validated the network of IMUs for future use in
biomechanical testing.

▼ The main goal of this dissertation has been to study
the inter-dependence between actions of the fingers of the human
hand. Earlier studies quantified finger inter-dependence in either
isometric conditions using force production tasks, or in nearly
isotonic conditions using finger movement tasks. We addressed a
common situation when a person holds an object using a subset of
the digits of the hand and moves one of the digits. Participants
moved one of the fingers (task finger) of the right hand trying to
follow a cyclic, ramp-like flexion-extension template at different
frequencies. The other fingers (non-task fingers) were restricted
from moving; their fingertip pressing forces were recorded and
analyzed. The index finger motion caused the smallest force
production by the non-task fingers. Larger forces were produced by
the neighbors of the task finger; these forces showed strong
modulation over the range of motion of the task finger. The forces
were higher during the flexion phase of the movement cycle as
compared to the extension phase. The index of enslaving expressed
in N/rad depended on the movement speed and was higher when the
task finger moved through the more flexed postures. These
observations suggest an important role of central, neural
mechanisms in the patterns of finger interdependence. They also
suggest that methods of analysis of finger coordination based on an
assumption of universal matrices of finger interdependence should
consider the specific features of the studied tasks.

▼ This purpose of this dissertation is to explore changes in the acromiohumeral interval during dynamic motion in the scapular plane. All of the experiments were completed in the Football Operations Athletic Training Room at Louisiana State University. The first experiment which investigated dynamic acromiohumeral interval changes in baseball players during a loaded and unloaded scaption exercise from 0°-75°, has been accepted for publication by the Journal of Shoulder and Elbow Surgery (in press, 2010). The mean acromiohumeral interval (AHI) for unloaded and loaded scaption decreased significantly (p<.001) from the arm at the side until 45° and loaded scaption narrowed AHI at 60° (p=.005) and 75° (p=.003). The second experiment investigates AHI and scapular upward rotation (SUR) changes in baseball and softball players during scaption exercises from 0°-75°. Significant load related narrowing of the AHI at 45°(p=.005), 60°(p=.001), and 75°(p<.001) and a significant load-position interaction (p=.001) at 0° and 75°was observed for all subjects. No gender differences in SUR or AHI were found. AHI and SUR displayed moderate positive correlations at 30° for both the unloaded scaption (r=.648, p=.001) and the loaded scaption (r=.445, p=.038) however, no significant relationships were present at 0°, 45°, 60° or 75°. The third experiment compared dynamic acromiohumeral interval and scapulohumeral rhythm changes in trained and untrained females during scaption exercises from 0°-90°. In general, AHI was maximal with the arm at the side and declined significantly (p<.001) during arm elevation until 60°, but increased significantly (p<.001) between 60° and 90°. Significant load related narrowing of the AHI at all positions (p<.05), a more negative SUR at 0° (p<.001) and a more positive SUR at 90° (p=.009) was observed for all subjects. Female athletes had significantly stronger external rotators (p<.001), larger overall AHI (p=.003) and more SUR (p=.008) than untrained females. Significant positive correlations (p<.05) between AHI and SUR were observed at 0°, 30°, and 60° during both loaded and unloaded scaption.

▼ Snake-like robots are low centre of gravity because they are limbless, they also have slender bodies composed of multiple actuating segments. Because of these features, snake robots are widely considered to be most adaptable among all land-based mobile robots. The multi-segmented body that provides their defining characteristic, adaptivity, also brings about the quandary of controlling many actuating segments simultaneously to create directd locomotion. Various methods for snake robot locomotion have been proposed for relatively smooth and flat surfaces. Currently there is no snake robot designed or locomotion method capable of resolving the directed mobility problem in situations where the snake robot is stuck at an impasse, or when it encounters disjointed terrains. There is no method to rapidly create new locomotion that addresses the problem or extensive time delay. This thesis makes the contribution of a modular snake robot called Striker and an elegant solution to create new snake-like robot locomotion on-the-fly, called the Explicit Gait Training (EGT) method. The EGT method allows trainer(s) to rapidly train new kinds of locomotion to address any situation at hand using their knowledge, experiences or even trial and error. The third contribution is the Standard Mobility for Snake Robots (SMMSR) is proposed as a standard platform to evaluate the evvectiveness of snake robot locomotion.

▼ In this dissertation a new modular design method for morphing wings is presented. First, a design method was created, applying modularity and recon gurability to a morphing wing system. With modularity being a requirement for the morphing wing system, a discretization method is developed to determine the discrete number of modules required to perform a desired morphing maneuver. Then, a specialized, modular, recon gurable variable geometry truss mechanism is proposed to facilitate morphing. The specialized modular wing truss is a recon gurable, limited mobility parallel mechanism, adapted to t within the volume of a wing. The mobility of the wing truss module is analyzed via a branch-based mobility and connectivity analysis that imposes kinematic requirements on the truss mechanism. The mobility and connectivity requirements are used to perform an enumeration analysis to isolate candidate module con gurations for morphing. Then, a parametric kinematic constraint system is developed and applied to the wing module and the kinematic performance of the module is evaluated. The
kinematics are applied to a mechanical prototype of the wing module for validation purposes. Finally, the
kinematics are used to evaluate the motion response of a wing skin system to lay the foundation for detailed design.

▼ I examine kinematic disturbance of star-forming gas in nearby galaxies, as part of the SAMI Galaxy Survey (SGS) on the Anglo-Australian telescope. Analysis of the frequency, causes, and nature of local galaxy disturbance will contribute to understanding galaxy evolution, one of the foremost areas of study in modern astronomy.
I calculate the fraction of galaxies within the SGS sample that are disturbed. A method based on kinemetry is used to measure the asymmetry in the gas kine- matics for each galaxy. A kinematic asymmetry coefficient (vasym) is calculated, which clearly distinguishes between perturbed and normal galaxies. This is not the case for quantitative morphology coefficients G, M20, and A.
Concentration of star formation and asymmetry are correlated, particularly for high stellar mass galaxies. There is an inverse link between vasym and stellar mass. Using data from the GAMA survey, it is found that the link between vasym and stellar mass is stronger than any trends in distance to first nearest neighbour (d1).
For high mass galaxies, there is an inverse trend between d1 and vasym, not lower stellar mass galaxies. That is, for low mass galaxies, internal gas dynamics drive vasym.
The Tully-Fisher relation (TFR) for our sample is shown. The TFR covers
7.5 < log(M∗/M8) < 11.0, with increased scatter at lower log(M∗/M8). There is a strong link between vasym and scatter below the TFR. Several causes of scatter are examined, and a slit placed on our velocity maps to compare with existing analysis. Misalignment between the kinematic and photometric position angles (PA) is linked to asymmetry and a significant cause of scatter, when the simulated slit is placed along the photometric PA. This demonstrates an important means of identifying the cause of and, where necessary, minimising scatter, in future TFR studies.

▼ Large riding lesson programs are an essential part of the horse industry. To meet demand and remain profitable, lesson barns sometimes require horses to work multiple times a day with different rider levels. There is little guidance as to the behavioral and physical effects of such protocols, so lesson program managers have limited scientific evidence upon which to base horse management and welfare decisions. The current data regarding horse and rider interactions includes motion pattern variability, trunk and spine
kinematics and force plate analyses. While these data are helpful to explain scenarios that can affect the horse with an accomplished rider or singular rider, to our knowledge no data exist that examine how riders with varying skill levels affect limb joint
kinematics. This research was designed to determine if rider experience level affects horses' movement, possibly resulting in increased physical effort by the horse. Secondarily, we aimed to determine if rider level affects changes in behavior patterns when ridden. Riders (n=8) were paired by skill level (beginner or advanced), and horses (n=8) were paired by sensitivity level (reactive or nonreactive). Horse and rider pairs were then randomly blocked into a repeated Latin square design using rider ability and horse sensitivity as factors. The Latin Square design created sixteen trials, each comprised of five passes in a prescribed path at the trot. Kinematic analysis was completed using high-speed video capture, and joint angles were calculated using digitizing software through MATLAB (MathWorks Inc., Natick, MA). An ANOVA was performed using JMP (SAS Institute Inc., Cary, NC) based on the repeated Latin square design. The Latin Square design allowed adjustment for horse sensitivity and rider level. The ANOVA suggested no differences in the measured joint angles between rider skill level or horse sensitivity level. To ensure that a subtle rider effect wasn't missed, all the kinematic measurements were subjected to a combined overall analysis with a combination of graphical techniques and MANOVA. While the combined analysis revealed no overall trends in the combined kinematic variables (p= 0.327), two variables, the front fetlock and stifle, trended towards significance of p=0.077 and p=0.096, respectively. Behaviors were quantified based on a designed ethogram and willingness scale, and each trial was videoed for analysis. Behaviors were analyzed by ANOVA, with the same Latin Square design that adjusted for rider level and horse sensitivity. There were no differences in behavior measurements as a result of rider skill level or horse sensitivity. While our data suggest no differences between beginner and advanced rider groups, future studies may reveal effects on joints during an entire stride cycle, in different gaits, and for longer periods.

▼ Running has been a popular sport because of convenience and health benefits. Fatigue among recreational runners may alter running mechanics, thereby increasing the risk for injury. The purpose of this study was to evaluate changes in lower extremity biomechanics throughout a 3.1 mile (5K) run. Ten male and ten female participants wore reflective markers to capture contralateral pelvic drop, knee adduction, knee abduction, and hip adduction. Participants ran 3.1 miles (5K) on a treadmill at a self-determined pace. A two-way, repeated measures ANOVA was conducted to capture the within-
subject data across time and between-
subject comparing differences in gender. Females had significantly greater contralateral pelvic drop but it did not change over time. Knee abduction angles significantly declined over the five observations. Gender differences and effects of distance can alter the biomechanics in recreational runners. More research is needed to identify predisposing factors to the development of chronic running injuries.

▼ Adolescent Idiopathic Scoliosis (AIS) is a three dimensional deformity of the spine that causes abnormal curvatures in the coronal and sagittal planes and abnormal vertebral rotations. The gold standard for diagnosing and tracking the progression of the deformity is through the use of repeated radiography and a patient can receive upwards of fifteen radiographic series over the course of treatment, which exposes this population to an increased risk of radiation-dependent complications.
This thesis presents the necessary calculations and the marker set required to make the motion capture technology a viable alternative to radiographs, in an effort to reduce the patient’s exposure to ionizing radiation. Using retro-reflective markers and force plates, it is possible to determine asymmetries in the frontal and transverse plane, to calculate the balance of the spine, to replicate common radiographic measures, and to determine the kinematic profiles of the spine for each patient.
The results of this work successfully showed that there is a high correlation between the radiographic measures and those calculated using motion analysis technology. When applied clinically, the results from a small set of AIS patients indicated that the motion analysis technology can help describe the underlying spinal and muscular deformities of patients with AIS. This work provides a viable means of reducing the number of radiographs this patient population is subjected to over the course of their non-operative treatment. It also provides a strong foundation for future work on applying motion capture technology to advance scoliosis research.

▼ Knee osteoarthritis affects up to 10% of adults in Western societies. Estimations on prevalence show over five times more patients in 2030. Conventional therapy does not provide sufficient and cost effective therapy. Joint distraction is currently considered as new treatment option. Preliminary studies explored the feasibility of knee joint distraction with experimental setups. Further evolvement of distractors should include accurate joint motion reproduction to improve circumstances for tissue recovery, to prevent joint damage, and to reduce immobilization of patients. A method was developed for patient specific joint motion reproduction. Evaluation was performed on cadaver joints and delivered a proof of principle. Within 40 degrees of flexion, a prototype was successfully evaluated for loadings present during natural joint loading. Application of the method can provide clinical and economic advantages by reducing invasiveness of procedures and by reducing costs with low complexity therapy and reduction of treatment time.
