▼ Many people with transtibial amputation rate the fit between their residual limb and prosthetic socket as the most important factor in the use of their prosthesis. Current research suggests that poor fit between the residual limb and the prosthetic socket can cause pain, skin breakdown or alteration of gait. This thesis focused on measurement methods to assess residual limb – prosthetic socket fit in people with transtibial amputation. Three aspects of fit were examined and new measurement methods for each aspect were explored.Fit affects the amount of relative movement that occurs between the residual limb and prosthetic socket. A method to measure this movement was proposed using motion capture analysis. The development and attempted validation of the method were outlined. Results were unpredictable and subject to confounding factors such as marker movement artefact. Therefore, the method was deemed not to be appropriate as a fit measurement tool in its current form. Based on these findings it was deemed necessary to investigate other measures of fit Fluctuation in residual limb volume can also affect fit. The reliability and validity of current residual limb volume measurement techniques were examined in a systematic review. Results demonstrated that circumferential measurements are the most reliable and valid tool currently available. The results from this review informed a study investigating the use of a low-cost optical scanner as a clinical volume measurement tool. Results found that the scanner was reliable when used by the same assessor but was not valid.The loading state at the prosthetic socket-residual limb interface is also an important factor in assessment of fit. The effect of pressure feedback to the prosthetist on the design of prosthetic sockets was assessed. It found that feedback resulted in reduction in pressure over anatomical regions of concern, and improved consistency between prosthetists. A new sensor to measure pressure and shear at the socket-limb interface was developed and benchtop testing was performed. These methods have the potential to aid in an improved understanding of the mechanisms that affect fit at the socket-limb interface of people with transtibial amputation. It is hoped that this can lead to improved fit and comfort for prosthetic users.

▼ Amputees are often prescribed prosthetic limbs with inertia properties far less than those of the limb they replace, and as a result an inertia asymmetry between legs is created. This inertia asymmetry has been suggested to contribute to the asymmetrical walking patterns often exhibited by unilateral amputees. Unilateral, transtibial amputees also typically expend 20% to 30% more metabolic energy than non-amputees walking at the same speeds. Reasons for these higher costs are not fully understood. This dissertation consists of four studies designed to better understand the influence of prosthetic leg inertia on the mechanics and energetics of amputee locomotion. Studies 1 and 2 investigated the process by which individuals adjust their gait patterns to accommodate an inertia manipulation of the lower extremity over a short term (over the first hour) and a longer term (eight days). In both unilateral, transtibial amputees and non-amputees, temporal and joint kinetic descriptors of gait changed within five minutes of exposure to an additional mass added distally to one leg. Over the course of the next eight days, these measures showed no further changes. The return to baseline values was equally rapid upon removal of the mass on the eighth day. Adjustment to the inertia change was nearly immediate, rather than a slow and gradual adjustment process. In study 3, the effects of multiple prosthetic leg inertia configurations on metabolic costs, kinematic symmetry, and temporal symmetry were investigated. In general, metabolic costs, kinematic asymmetries, and temporal asymmetries increased systematically with increasing prosthetic inertia. The lowest metabolic cost and most symmetrical walking patterns were observed when amputees walked without mass added to their prosthetic leg, (i.e., walked with their normal prosthesis). Thus, the use of a lightweight prosthesis appeared to minimize gait asymmetries and metabolic costs during walking. Study 4 addressed the effects of multiple prosthetic leg inertia configurations on intersegmental dynamics and lower extremity muscle excitations during walking. With respect to the prosthetic leg, absolute angular impulses of the muscle, interaction, and gravitational moments of the hip and knee increased systematically during swing. During stance of the prosthetic leg, absolute angular impulses of the interaction and gravitational moments at the hip and knee also increased systematically with increasing inertia, whereas the muscle moments were unaffected. Intersegmental dynamics of the intact leg during the entire gait cycle were minimally affected by increases in prosthetic leg inertia. In general, these results suggested increases in prosthesis inertia increased demands on the musculature during the swing phase of the prosthetic leg. EMG data did not support our finding of increased muscle demand on the prosthetic leg during swing. Results of studies 3 and 4 provide no indication that the current practice of using of lightweight prostheses is contraindicated or can be improved upon… Advisors/Committee Members: Philip Martin, Committee Chair/Co-Chair, John Henry Challis, Committee Member, Stephen Jacob Piazza, Committee Member, Robert L Sainburg, Committee Member, Henry Joseph Sommer Iii, Committee Member.

▼ Afferent feedback is important for modulating locomotion and maintaining stability. Studying locomotor extremes and applying perturbations to normal locomotion allows us to probe the effects of afferent feedback on the control of normal gait. Investigating the walk-to-run gait transition specifically provides a unique locomotor event to investigate the fundamental determinants of legged locomotion (walking or running) and identify the sensory inputs important to the ongoing neuromuscular control of walking and running. The first goal of this dissertation was to investigate the contributions of plantarflexor muscles during stance (Aim 1) and flexor muscles during swing (Aim 2) to the walk-to-run transition. To accomplish this I used unilateral, transtibial amputee subjects as a means to assess the affects of unilaterally eliminating plantarflexor propulsive force production and below-knee flexor activation on the walk-to-run transition speed. The main objective of Aim 1 was to determine the preferred gait transition speeds of unilateral, transtibial amputee subjects, and the influence of kinetics on the walk-to-run gait transition speed. Unilateral, transtibial amputee subjects transition between gaits at a lower speed than able-bodied controls and are still able to generate higher propulsive forces walking at speeds above their preferred gait transition speed. This finding indicates that their walk-to-run transition is not likely dictated by the force-length-velocity characteristics of the intact plantarflexor muscles. Thus, as an experimental model, unilateral, transtibial amputee subjects can provide unique insights for decoupling the previously identified performance limit of plantarflexor muscles from the preferred gait transition speed in order to probe other potential determinants. The main objective of Aim 2 was to quantify the muscle activation during walking and running gaits relative to the walk-to-run gait transition speed for unilateral, transtibial amputee subjects. The swing phase tibialis anterior muscle activation is a major determinant of the walk-to-run transitions in unilateral, transtibial amputee subjects. Swing phase dorsiflexion moments alone do not explain these results and additional work is necessary to probe potential mechanical and neural explanations. Furthermore, in unilateral, transtibial amputee subjects, swing-phase rectus femoris and biceps femoris long head activations and their respective joint moments are a function of changes in absolute speed and thus not indicative of their significantly lower gait transition speed. The second goal of this dissertation was to probe the potential contributions of afferent feedback to the underlying neuromuscular mechanism ultimately responsible for the transition (Aim 3). The main objective of Aim 3 was to evaluate the effects of contralateral sensory loss on the motor output of the ipsilateral leg. Unilateral below-knee, ischemic deafferentation has significant effects on both inter- and intra- limb motor output. The net effect of contralateral… Advisors/Committee Members: Chang, Young-Hui (advisor), Nichols, T. Richard (committee member), Prilutsky, Boris I. (committee member), Neptune, Rick R.

Syfte: Syftet med det här examenarbete är att undersöka behovet av snabbkopplingsadaptrar för protesbrukare. Bakgrund: Snabbkopplingsadapter är en förhållandevis ny produkt som både Otto Bock och Lindhe Xtend erbjuder, men ingen forskning på behovsområdet finns ännu gjord. Fördelen med produkten är enligt leverantörernas hemsidor bl a att man med den enkelt kan byta mellan olika proteskomponenter utan att behöva skruva på några protesinställningar eller byta hylsa. Metod: För att undersöka behovet av snabbkopplingsadaptrar utfördes semistrukturella intervjuer av fenomenologisk karaktär. En serie med sju frågor sammanställdes som intervjuunderlag, vilka togs fram utifrån de tre behovsfokusområdena: Funktion, delaktighet och livskvalité. I undersökningen ingick n=6 deltagare, varav n=3 transtibialt amputerade och n=3 transfemoralt amputerade. Insamlade data analyserades vidare för framtagning av olika teman och resultat. Resultat: Utifrån intervjuunderlaget togs följande teman fram: Byte av protesfötter/protesknäleder, På- och avtagning av byxor, Hylspassform, Transport samt Biomekanik. Varje tema utgjorde ett eget potentiellt användningsområde, där de största behoven visade sig ligga inom temana Byte av protesfötter/protesknäleder, Hylspassform samt Transport. Slutsats: Behovet av snabbkopplingsadaptrar är högst subjektivt, och beror snarare på deltagarens liv än några allmänna faktorer. Däremot upptäcktes ett antal tänkbara användningsområden för den.

Aim: The aim of this thesis was to investigate the necessity of the quick change adapter for lower limb amputees. Background: Quick Change Adapter is a relatively new product that both Otto Bock and Lindhe Xtend offers, but no research has been done on the area of its necessity yet. According to the supplier´s websites the benefits of the product is that you with it easily can change prosthetic components without affecting the alignments or change socket. Method: To investigate the necessity of the Quick Change Adapter, semi structural interviews of phenomenological characteristic were used. A series of seven questions were compiled as a basis for the interview from the three focus areas: Function, participation and quality of Life. The thesis involved n=6 participants, of who n=3 was trantibial amputated and n=3 transfemoral amputated. Collected data was later analysed to find general themes and results. Results: From the interviews these themes were…

Tyrimo problema: asmuo, kuriam atlikta blauzdos amputacija, susiduria su įvairiais kasdienės veiklos, mobilumo sunkumais. Paveikiama ne tik jo psichoemocinė būsena, bet ir visas atramos–judėjimo aparatas. Reabilitacijos metu daug dėmesio skiriama eisenos ir pusiausvyros lavinimui, nes tai turi labai didelę reikšmę šių asmenų savarankiškumui. Mes bandėme išsiaiškinti, ar veidrodžių, kaip grįžtamojo ryšio panaudojimas kineziterapijos metu, turi įtakos pusiausvyros atsigavimui ir ėjimo greičiui po blauzdos amputacijos. Tyrimo objektas: kineziterapijos priešais veidrodžius poveikis asmenų, kuriems amputuota blauzda, pusiausvyrai ir ėjimo greičiui. Tikslas – įvertinti kineziterapijos priešais veidrodį poveikį asmenų, kuriems amputuota blauzda, pusiausvyrai ir ėjimo greičiui. Hipotezė: manome, kad taikant kineziterapiją priešais veidrodį asmenų, kuriems atlikta blauzdos amputacija, pusiausvyra ir ėjimo greitis atgaunami geriau nei taikant kineziterapiją be veidrodžių. Uždaviniai: 1. Įvertinti asmenų, kuriems atlikta blauzdos amputacija, pusiausvyrą bei ėjimo greitį kineziterapijos pradžioje ir po kineziterapijos priešais veidrodį procedūrų. 2. Įvertinti asmenų, kuriems atlikta blauzdos amputacija, pusiausvyrą bei ėjimo greitį kineziterapijos pradžioje ir po įprastinės kineziterapijos procedūrų. 3.

Research problem: human faces a variety of difficulties in activities of daily living and mobility after leg amputation. It is affected not only psychoemotional state but also all the locomotor apparatus. Rehabilitation focuses on the gait and balance training, as this has important implications for the further development of human independancy level. We attempted to ascertain whether the mirrors as the use of feedback during physiotherapy have an effect for the recovery of balance and gait after transtibial amputation. Object: effectiveness of physiotherapy including mirrors for the recovery of balance and gait after transtibial amputation. Objective: to assess the effectiveness of physiotherapy in front of the mirror for balance and walking speed in persons after transtibial amputation. Hypothesis: we consider that the application of physical therapy in front of the mirror for persons who underwent transtibial amputation helps to recover balance and walking speed better than applying physical therapy without mirrors. The aims: 1. To rate balance and walking speed of patients who underwent transtibial amputation at the beginning of physiotherapy and after physiotherapy in front of a mirror procedures. 2. To rate balance and walking speed of patients who underwent transtibial amputation at the beginning of physiotherapy and after conventional physiotherapy procedures. 3. To compare balance and walking speed of subjects who were applied physiotherapy in front of the mirror and... [to full text]

▼ Patients with unilateral dysvascular transtibial amputation (TTA) adopt movement compensations that are required to maintain balance and achieve ambulation in the absence of ankle plantar flexion, and result in increased and asymmetric joint loading patterns. As a result, this population is at an increased risk of overuse injuries, such as low back pain (LBP). Clinical gait analysis is used to guide diagnostics in movement retraining following amputation, and is performed using instrumented (research based) or observational analyses (clinically based). However, instrumented analyses are currently impractical in most clinical settings due to expense and computational limitations. This dissertation presents the use of segmental angular momentum to describe movement compensations in patients with TTA, and assess their effects on the musculoskeletal system; which provides a potential platform applicable in both instrumented and observational settings. Ten patients with unilateral dysvascular TTA and two cohorts (patients with diabetes mellitus and healthy controls) completed one experimental study in which whole-body kinematics and core muscle demand were collected during walking and bilateral stepping tasks. Specific Aim 1 described the foundations of the separation of angular momentum into two components, translational (TAM) and rotational angular momentum (RAM) to describe movement coordination during healthy walking. Euler's rotational laws were used to calculate segmental translational and rotational moments, which provide insight into the effort required to generate and arrest momentum by their relation to external forces and moments. Specific Aim 2 described trunk and pelvis movement compensations in patients with TTA during walking using TAM and RAM. Specific Aim 3 described the trunk translational and rotational moments in patients with TTA during step ambulation. Finally, Specific Aim 4 described the demand from the core musculature that supports trunk movement compensations in patients with TTA during step ambulation. The results from these Specific Aims indicate that patients with TTA generate larger amounts of TAM and RAM, which were caused by larger translational and rotational trunk moments and demand from core muscles, than healthy controls. These compensations alter the low back loading patterns, which may be reduced by targeted strengthening and retraining motor control compensations to better support trunk movements.

▼ Transtibial amputees are at increased risk of contralateral hip and knee joint osteoarthritis, likely due to abnormal biomechanics. Biomechanical challenges exist for transtibial amputees in gait and cycling; particularly, asymmetry in ground/pedal reaction forces and joint kinetics is well documented and state-of-the-art passive and powered prostheses do not fully restore natural biomechanics. Elliptical training has not been studied as a potential exercise for rehabilitation, nor have any studies been published that compare joint kinematics and kinetics and ground/pedal reaction forces for the same group of transtibial amputees in gait, cycling, and elliptical training. The hypothesis was that hip and knee joint kinematics and kinetics and ground and pedal reaction forces would differ due to exercise (gait, cycling, elliptical) amputee status (amputated, control [non-amputated]), and leg (dominant [intact], non-dominant [amputated]). Ten unilateral transtibial amputees and ten control participants performed the three exercises while kinematic and kinetic data were collected. Hip and knee joint flexion angle, resultant forces, and resultant moments were calculated by inverse dynamics for the dominant and non-dominant legs of both participant groups. Joint biomechanics and measured ground/pedal reaction forces were then compared between exercises, between the dominant and non-dominant legs within each participant group, and across participant groups. Significant differences in hip and knee joint flexion angles and timing, compressive forces, extension-flexion (EF) and adduction-abduction (AddAbd) moments, and anterior-posterior (AP) and lateral-medial (LM) reaction forces were found. Particularly, transtibial amputees showed maximum knee flexion angle asymmetry as compared to controls in all three exercises. Maximum hip and knee compressive forces, EF moments, and AddAbd moments were lowest in cycling and highest in gait. Asymmetry in amputee midstance knee flexion and timing in v gait, coupled with low maximum EF moment for the non-dominant leg, suggests that amputees avoid contraction of the non-dominant quadriceps muscle. Knee flexion angle and EF moment asymmetry in elliptical training suggests that a similar phenomenon occurs. Asymmetry in AP and LM reaction forces in gait, but not other exercises, suggests that exercises that constrain kinematics reduce loading imbalances. The results suggest that cycling and elliptical training should be recommended to transtibial amputees for rehabilitation due to reduced hip and knee joint forces and moments. Elliptical training may be preferred over gait due to decreased joint loading and loading asymmetry, but some asymmetry and differences from control participants still exist. Non-weight bearing exercises such as cycling may be best at reducing overall joint loading and joint load asymmetry but do not eliminate all kinematic and temporal asymmetries. Current state-of-the-art prosthetic leg design is insufficient in restoring natural biomechanics not only in gait but… Advisors/Committee Members: Stephen M. Klisch.

▼ For many years, the biggest issue that causes discomfort and hygiene issues for patients with lower limb amputations have been the interface between body and prosthetic, the socket. Often made of an inflexible, solid polymer that does not allow the residual limb to breathe or perspire and with no consideration for the changes in size and shape of the human body caused by changes in temperature or environment, inflammation, irritation and discomfort often cause reduced usage or outright rejection of the prosthetic by the patient in their day to day lives. To address these issues and move towards a future of improved quality of life for patients who suffer amputations, Loughborough University formed the Next Generation Prosthetics research cluster. This work is one of four multidisciplinary research studies conducted by members of this research cluster, focusing on the area of Computer Aided Design (CAD) for improving the interface with Additive Manufacture (AM) to solve some of the challenges presented with improving prosthetic socket design, with an aim to improve and streamline the process to enable the involvement of clinicians and patients in the design process. The research presented in this thesis is based on three primary studies. The first study involved the conception of a CAD criteria, deciding what features are needed to represent the various properties the future socket outlined by the research cluster needs. These criteria were then used for testing three CAD systems, one each from the Parametric, Non Uniform Rational Basis Spline (NURBS) and Polygon archetypes respectively. The result of these tests led to the creation of a hybrid control workflow, used as the basis for finding improvements. The second study explored emerging CAD solutions, various new systems or plug-ins that had opportunities to improve the control model. These solutions were tested individually in areas where they could improve the workflow, and the successful solutions were added to the hybrid workflow to improve and reduce the workflow further. The final study involved taking the knowledge gained from the literature and the first two studies in order to theorise how an ideal CAD system for producing future prosthetic sockets would work, with considerations for user interface issues as well as background CAD applications. The third study was then used to inform the final deliverable of this research, a software design specification that defines how the system would work. This specification was written as a challenge to the CAD community, hoping to inform and aid future advancements in CAD software. As a final stage of research validation, a number of members of the CAD community were contacted and interviewed about their feelings of the work produced and their feedback was taken in order to inform future research in this area.

▼ Predictive simulations predict human gait by solving a trajectory optimization problem by minimizing energy expenditure. These simulations could predict the effect of a prosthesis on gait before its use. This dissertation has four aims, to show the application of predictive simulations in prosthesis design and to improve the quality of predictive simulations. Aim 1 was to explain joint moment asymmetry in the knee and hip in gait of persons with a transtibial amputation (TTA gait). Predictive simulations showed that an asymmetric gait required less effort. However, a small effort increase yielded a gait with increased joint moment symmetry and reduced joint reaction forces. This suggests that gait training could reduce the risk of developing osteoarthritis in persons with a transtibial amputation. Aim 2 was to compare the effect of different prosthesis alignments on TTA gait. Predictive simulations were solved using a three-dimensional musculoskeletal model with different prosthetic alignments. A flexion alignment of the prosthesis might be favored over a neutral alignment, since the metabolic cost and joint reaction forces were lower, though the differences were small. Also, predictions indicated that a lateral translation or an external rotation could alleviate skin problems by reducing skin-to-socket stresses. Aim 3 was to compare the gait objective of minimizing metabolic energy to minimizing muscular effort. Four metabolic energy expenditure models were selected after an experiment to compare metabolic cost calculated with seven metabolic energy models to metabolic cost from pulmonary gas exchange measurements. The minimum energy solution was more similar to normal gait in joint angles, while the minimum effort solution was more similar in joint moments, especially at the knee. However, neither solution could entirely explain human gait. Aim 4 was to propose an approach to optimize in a stochastic environment and implement it to explain antagonistic muscle co-contraction in human movement. In a stochastic environment, muscle co-contraction was energy optimal for certain tasks and nonzero foot clearance was energy efficient. The approach was then applied to TTA gait to explain co-contraction of the upper-leg muscles on the prosthesis side. The results suggested that antagonistic co-contraction is energy optimal for human gait. Advisors/Committee Members: van den Bogert, Antonie (Advisor).

▼ The performance of dynamic prosthetic foot devices is influenced by both the functional design and alignment of the device in the prosthetic system. Although this is recognized, studies of the interaction of these factors are limited. One measure of performance in unilateral transtibial amputee gait is the progression of the centre of pressure (COP) throughout stance. Recently, Klenow et al., developed a method of quantitatively identifying the “dead spot” phenomenon (DSP), described as an interruption of the forward progression of prosthetic foot COP during stance in amputee gait, as measured by COP progression velocity. The aim of this study was to isolate the effects of sagittal alignment changes on three DSP measures in the rearfoot and forefoot. These were: 1) DSP Time – the duration of the interruption in forward progression, 2) DSP Magnitude – the minimum forward velocity during the interruption and 3) DSP Progression – the displacement of the COP during the interruption. A study was designed in which a cohort of patients representing a range of prosthesis users were assessed in a clinical setting at the time of alignment of their prosthetic system. A custom portable gait analysis system was fabricated and commissioned to analyse over-ground walking trials of eight unilateral transtibial amputees fitted with prescribed prosthetic devices. Rearfoot and forefoot DSP of the intact and affected limbs were analysed during pre-alignment and post-alignment conditions using the three DSP measures. DSP Progression was determined to be a clinically appropriate measure, capturing the effect of clinical alignment in the sagittal plane with the presence of observed DSP. Observed effects of alignment corresponded with clinical goals in forward progression and limb symmetry. Based on the analysis of aligned systems completed by the partnered prosthetist, recommendations of clinically significant values were determined to be 4mm of rearfoot DSP Progression and 3.5mm of asymmetry in rearfoot DSP Progression. Forefoot DSP Progression was observed to increase on average of 4mm in the intact limb. The recommended DSP values can be used as a clinician tool to confirm alignment changes and to help develop prosthetic foot prescription guidelines related to DSP.

▼ Myoelectric algorithms have the potential to provide motion intent information to a prosthetic system to allow the prosthetic to adapt biomimetically to changes in walking modality. While myoelectric algorithms have been explored extensively for upper limb amputees, little has been done to achieve similar advances for the lower limb. For upper limb amputees, it has been shown that fusion of myoelectric and inertial sensors benefits classification. Myoelectric signals from four muscle groups (tibialis anterior, medial gastrocnemius, vastus lateralis, and biceps femoris) and inertial signals from the lower limb segments were recorded for five non-amputee subjects and five transtibial amputees over a variety of walking modes: level ground walking at various speeds, ramp ascent/descent, and stair ascent/descent. These signals were decomposed into relevant features (mean absolute value, variance, wavelength, number of slope sign changes, and number of zero crossings, maximum, minimum) and used to test the ability of myoelectric classification algorithms for transtibial amputees using either Linear Discriminant Analysis (LDA) or Support Vector Machine (SVM) classifiers. The fusion of myoelectric and inertial signals showed no benefit for amputee subjects and as a result inertial signals were removed from consideration. Detection of all seven walking modes were observed to have an accuracy of 97.9% (± 0.22) and 97.9% (± 1.39) for amputee subjects when using LDA and SVM, respectively. The predominant misclassifications occurred between different walking speeds due to the similar nature of the gait pattern. Stair ascent/descent modalities had the best classification accuracy with 100% (± 0.00) and 99.8% (± 0.29) for amputee subjects when using LDA and SVM, respectively. Transitions into and out of stair modalities could be predicted one gait cycle ahead of the change for 95.0% and 90.0% of all transitions observed in this study when using LDA and SVM, respectively. The robustness of the developed classifier was explored through tests of generalizability and stability under electrode shifting disturbance. While separations between certain modes were not possible through a generalized model or under disturbance, stair ascent/descent classification against all other modalities was consistent. This result highlights the possibility of a stair mode myoelectric control algorithm for lower limb amputees. Future efforts will further explore the robusticity of myoelectric classification under real world conditions such as stability of classification over long periods of time, classifier training methods, and real time capabilities of the classifier.

▼ Current socket casting methods used in under-resourced environments are highly reliant on the skill and experience of the prosthetist. Pressure-casting methods have been advocated to reduce skill dependency in socket casting. To date, however, socket production studies have only been performed in resourced settings and involved qualified prosthetists. In this thesis, a pressure-casting method to reduce the skill dependency in socket casting has been described in detail. Appropriate and feasible measures to assess wearer outcomes comprised standard functional tests, spatio-temporal gait parameters, subjective measures of user satisfaction and quantification of the limb-socket interface pressures. The participants of all studies herein were adults with unilateral transtibial amputations. All studies were conducted in Vietnam and utilised pressure-cast (PCAST) sockets with low-cost polypropylene components. All sockets were cast by local orthopaedic technicians when appropriate. Wearer outcomes with the PCAST sockets were similar to the participants’ original prosthetic limbs and high levels of satisfaction were recorded following an extended usage period of five months. Temporal gait changes suggested greater willingness to load the prosthetic limb over the usage period. In contrast, satisfaction and comfort data suggested that feelings of comfort and stability decreased over the usage period. As a baseline, the participants’ original prostheses were not consistent due to varying age, quality and socket design. Thus, the outcomes of participants fit with both PCAST and PTB sockets were compared. The results showed no significant differences in the initial participant functionality, spatio-temporal gait characteristics, gait symmetry, or comfort between the skill-dependent PTB socket and the PCAST socket. PCAST socket fit was investigated by examining interface pressure distribution, magnitude and duration and exploring how these pressures vary with wearer comfort. The pressure distribution was non-uniform with high pressures identified at the bony prominences, especially the tibial crest. The duration, rather than magnitude, of these pressures, appeared to influence wearer comfort. High pressures in the anterior proximal region and longer loading durations at the lateral proximal and medial distal regions also potentially affected wearer comfort. These data may assist future researchers in analysing and interpreting socket interface pressures. The staged phasing of data collection periods permitted continual development of the PCAST technique. Wearing a thick sock during casting appeared to reduce tightness and pain around the tibial condyles. Thus, the use of a thick cotton sock during casting was deemed beneficial. Further research, including interface pressure analysis, is required to determine if using a Pelite liner with the PCAST socket improves wearer outcomes. This research has shown the PCAST technique is able to produce a functional, biomechanically sound and satisfactory socket for prosthetic…

▼ Individuals with unilateral transtibial amputations (ITTAs) are at a greater risk of developing knee joint degenerative diseases in the intact limb compared to the general population. However, equivocal results from walking gait literature have found limited differences in load between the intact limb of ITTAs and control limbs. This thesis postulated that 1) data extraction of discrete points in loading signals are inconsistent; 2) other loading features, not previously considered, may more appropriately quantify load; and 3) overloading may be more prominent in tasks which have greater loading and joint movement demands. Therefore, this thesis aimed to determine if the intact limb of ITTAs had significantly different limb and knee joint loading patterns and underpinning mechanics compared to able-bodied controls during high loading activities. Eight ITTAs and twenty-two controls performed step descent and unilateral and bilateral drop landing tasks as experimental models to increase load. Loading waveforms were assessed using statistical parametric mapping as an alternative to discrete point analysis. Waveform analysis was able to identify loading rates (rather than peak magnitudes) as important measures of load and identify additional phases of interest when loading the limb. Anterior-posterior loading was also found to be an important feature in addition to the commonly examined loading features. The intact limb of ITTAs in this thesis was able to adapt to higher loading activities by adopting joint mechanics similar to controls despite reductions in quadriceps strength. Therefore, few differences were found in the whole-limb and knee joint loading patterns. This would suggest that high load in the intact limb compared to a control limb may not suggest an increased risk of knee joint degeneration but rather the asymmetry between prosthetic and intact limbs. Additionally, it is just as plausible to suggest that high limb loading is not the mechanism of injury in ITTAs.

▼ The foot, ankle and surrounding musculature play key roles in walking and maneuvering. They provide not only body support but also forward propulsion, terrain adaptation, and contributions to mediolateral balance control. Prosthetic feet have previously been designed to provide body support and, to some degree, forward propulsion and sagittal-plane terrain adaptation. However, there has been little exploration of how prosthesis design affects performance in tasks that challenge mediolateral balance, such as turning and walking on cross-slopes. In Chapter 2, the effects of prosthetic foot stiffness on unilateral transtibial amputee gait during turning were explored. Changes found in sagittal-plane kinematics and kinetics caused by more compliant prostheses were similar to those seen previously in studies of straight-line walking. This included decreased body support, increased residual limb propulsion and greater limb flexion. Mediolateral balance, measured by peak-to-peak range of whole-body angular momentum, improved with decreasing stiffness, but adaptations in coronal-plane angles, work and ground reaction force impulses were less systematic. In Chapter 3, forward dynamics simulations of a unilateral transtibial amputee stepping on a cross-slope were used to identify optimal coronal-plane stiffness profiles that improved balance control by decreasing changes in coronal-plane whole-body angular momentum. Profiles that decreased these changes were identified for ankle-inverting and ankle-everting cross-slopes as well as level ground. The change in coronal-plane whole-body angular momentum decreased with an increase in stiffness for ankle-everting cross-slopes but with a decrease in stiffness for ankle-inverting cross-slopes and level ground. Stiffness profiles influenced mediolateral balance control through the medial GRF, but were specific to each surface type. These results highlight the need to identify the surface type encountered (level, ankle-inverting or ankle-everting cross-slope) so that the stiffness profile appropriate for the surface can be set. To that end, in Chapter 4, measurements from the residual limb useful for predicting a cross-slope with a pattern recognition algorithm were identified. Residual limb kinematics, especially measurements from the foot, shank and ankle, were found to successfully predict the surface type with high accuracy. These studies have provided rationale and foundation for designing prostheses that help maintain mediolateral balance control when encountering turning or uneven terrain.

▼ Individuals with a lower-limb amputation have an increased prevalence of chronic low back pain (LBP), relative to the general adult population. Altered, dynamic whole-body biomechanics resulting from limb loss are thought to be a primary cause of the increased susceptibility. However, biomechanical LBP development is a multi-factorial problem, and a definitive cause has yet to be ascertained using only traditional, laboratory methods. Thus, the purpose of this work was to compare dynamic, in vivo low back biomechanics between individuals with and without unilateral, transtibial amputation during walking, estimated using patient-specific computational modeling and simulation. A generic, muscle-actuated whole-body model with additional detail in the L1-L5 lumbar was adjusted to represent each individual. Experimentally-measured motion capture, ground reaction force, and surface electromyography for each individual were used to simulate a gait cycle to estimate concurrent internal low back biomechanics. Results showed several group differences in computed low back metrics during particular phases of the gait cycle. Most significant in individuals with an amputation was greater lateral trunk motion towards the residual side during residual single limb stance, concurrently with greater intact-side trunk muscle forces and a greater L4L5 lumbar joint contact force. A greater range of axial trunk rotation near toe off of the residual limb was also found concurrently with greater force in residual-side erector spinae and psoas. The repetition of such abnormal biomechanics over time has potential to cause deficiencies in muscular endurance, strength asymmetries, inhibited proprioception, and myofascial pain, each associated with increased susceptibility to chronic, biomechanical LBP and other secondary musculoskeletal disorders. This work contributes to a broader goal of developing computational modeling and simulation into a supplementary clinical tool to aid in diagnosis and treatment of biomechanical disorders.
