▼ Nos pacientes amputados, o método convencional de fixação da prótese com o membro residual ocorre através da utilização de um encaixe protético, sendo este confeccionado sob medida. Alterações no volume do coto de amputação ocasionam desconforto e dor no uso da prótese e lesões de pele, trazendo ao usuário dificuldade de utilização. Além disso, os pacientes experimentam alterações na marcha e diminuição da amplitude de movimento. O sistema de fixação de prótese diretamente ao osso é uma alternativa para melhorar a qualidade de vida de pacientes amputados, visto que resultam em maior conforto, menor quantidade de lesões, maior controle da prótese e menor alteração da marcha. Com a evolução das técnicas de osseointegração, estudos vêm sendo realizados com o objetivo de aprimorar a tecnologia protética, tanto em termos de compatibilidade com o paciente, como em custo e produção. Este projeto teve como objetivo desenvolver um dispositivo de prótese osseointegrada para pacientes amputados transfemorais. Para tanto, uma análise detalhada dos produtos existentes nos mercados do exterior, seguida de um processo de desenvolvimento de produto, foi realizada a fim de projetar um sistema de próteses osseointegradas para pacientes amputados transfemorais. Este estudo avalia componentes presentes nos sistemas de osseointegração existentes no mercado, e com base em um levantamento de características mecânicas de diversos biomateriais metálicos, elaborou-se um protótipo de adaptador intermediário transcutâneo, adaptador externo e demais componentes adjacentes compostos de CrCoMo. O projeto foi então avaliado através de simulações em software para assegurar que seus requisitos mecânicos mínimos fossem atingidos. A posterior fabricação do protótipo funcional, uma simulação do procedimento cirúrgico em cadáver e um ensaio mecânico foram executados a fim de testar parâmetros como combinações e tamanhos de peças adequados, e técnicas cirúrgicas para a implantação da prótese. Levando-se em conta que este protótipo utiliza tecnologia nacional e os materiais utilizados estão disponíveis no mercado brasileiro, estima-se que o mesmo terá um grande valor tecnológico para o Brasil e um menor custo de produção. Concluímos que o projeto de prótese osseointegrada para amputados transfemorais pode ser produzido com tecnologia nacional.

Bakgrund Att ha en transfemoral (TF) amputation har en stor inverkan på den amputerades liv med bl.a. större risk för fall, lägre gånghastighet och smärta. I dag är utbudet av kvalitativa studier som visar på hur TF-amputerade upplever sin vardag, mycket begränsat. Det saknas helt studier som tar upp hur det är att ha ett föräldraansvar när man är TF-amputerad. Syfte Syftet med studien var att se om det fanns några självupplevda problem i vardagen för unilateralt TF-amputerade i föräldrarollen kopplad till deras protes-användning. Metod Kvalitativa semistrukturerade intervjuer genomfördes med fyra TF-amputerade pappor. Dessa analyserades och tematiserades. Resultat Vid analysen hittades nio huvudteman: Ansvar, relation med barnen, svårigheter med spontanitet, aktiviteter, miljörelaterade problem, oro, energi och smärta, säkerhet. Deltagarna upplevade bristande delaktighet, fler konflikter med sina barn och bristande energi. Slutsats Det finns ett flertal självupplevda problem för TF-amputerade föräldrar och dessa berör främst känslan av delaktighet, relationen med barnen så väl som rent praktiska aspekter.

Background Having a transfemoral (TF) amputation has a major impact on the amputee's life, such as greater risk of falls, lower walking speed and pain. Today, there are no qualitative studies that show how TF-amputees experience their everyday lives and there are no studies that address what it is like to have parental responsibility when you are TF-amputated. Purpose The aim of this study was to see if there were any self-experienced problems in the everyday life of unilateral TF amputees in the parental role linked to their prosthetic use. Method Qualitative semi-structured interviews were conducted with four TF-amputated fathers. These were analysed and thematised. Results Nine main themes were detected during the analysis: Responsibility, relationship with the children, difficulties with spontaneity, activities, environment-related problems, concern, energy and pain and safety. Participants experienced lack of participation, more conflicts with their children and lack of energy. Conclusion There are self-experienced problems for TF-amputated parents, and these affect the sense of participation, the relationship with the children and practical aspects

▼ This thesis presents and experimentally implements five different robust, adaptive, and robust adaptive controllers as the first steps towards using model-based controllers for transfemoral prostheses. The goal of this research is to translate these control methods to the robotic domain, from bipedal robotic walking to prosthesis walking, including a rigorous stability analysis. The human/prosthesis system is first modeled as a two-domain hybrid asymmetric system. The model upon which the controllers are based is a 5-link planar hybrid system (both continuous and discrete behaviors) with point feet, to represent a transfemoral amputee’s body and limbs. An optimization problem is formulated to obtain a stable human-like gait. The proposed controllers are then developed for the combined human/prosthesis model and the optimized reference gait. The stability of all five controllers is proven using the Lyapunov stability theorem and Barbalat’s lemma, ensuring convergence to the desired gait. The proposed controllers are first verified on a bipedal walking robot as a hybrid human/prosthesis model in simulation. Simulations show that the proposed controllers are capable of meeting specific performance requirements regarding trajectory tracking of the prosthetic knee, convergence to a stable periodic orbit, and robustness to force/obstacle disturbances while walking on flat ground. They are then experimentally tested on a treadmill with an able-bodied subject using AMPRO3 (the third iteration of Advanced Mechanical Prosthesis), a custom self-contained powered transfemoral prosthesis. Results show that all controllers provide humanlike walking and accurate tracking performance for a healthy human subject utilizing a transfemoral prosthesis. Finally, outdoor tests are carried out using AMPRO3 with three test subjects walking on level ground, uphill slopes, and downhill slopes at slope angles of 3 and 8 degrees, to demonstrate walking in different real-world environments.

▼ Background There are more than 300,000 persons in the U.S. living with transfemoral amputation (TFA). Persons with TFA use a knee prosthesis for gait and mobility. Presently, the C-Leg microprocessor knee prosthesis is the standard of care. C-Leg has significantly improved safety and cost efficacy and has created modest gains in gait efficiency. Recently, a new prosthesis has introduced a new sensor array and processor that reportedly improves knee motion, stair function and standing stability. Early claims of the reported functional benefits of the new Genium knee (formerly X2) have not been validated in a rigorous clinical trial. Therefore, the purpose of this project was to determine if the Genium knee improves safety, function and quality of life compared to the current standard of care (C-Leg). Methods The study is a randomized AB crossover with a control group. Subjects must have used (and still be using) a C-Leg for a minimum of 1yr prior to enrollment. Inclusion criteria beyond this are unilateral transfemoral or knee disarticulation amputation for any etiology, community level ambulation (Medicare level 3 or above), independent ambulation and ability to independently provide written, informed consent. Once enrolled subjects utilize their same socket but receive a study foot (Trias or Axtion). Subjects are randomly assigned to either stay with their C-Leg or be fit with a Genium knee. Subjects accommodate and test (A phase) then crossover to the other knee condition and repeat the testing (B phase). A follow up phase of the study beyond the B phase is ongoing to study longer term preference. For AB assessment, three domains were assessed: Safety, function and quality of life. For safety, the PEQ-A survey of stumbles and falls, posturography (Biodex SD limits of stability and postural stability tests), 4 square step test and 2 minute ramp stand test were completed. For function, a series of timed walking tests, the amputee mobility predictor, kinematic gait assessment and physical functional performance-10 tests were conducted. For quality of life, the socioemotional and situational satisfaction domains of the population specific and validated PEQ (prosthesis evaluation questionnaire) were completed. Results Safety: Posturographic assessment revealed impairment between transfemoral amputees and non-amputees. Stumbles and semi-controlled falls decreased with Genium but were not significantly different. Four square step testing was significantly (p 0.05) improved from 12.2s(3.3) to 11.1s(3.4) for the C-Leg and Genium respectively. Function: Kinematic asymmetry was minimally different between knee conditions. The AMP mean(SD) scores while subjects used C-Leg was 40.8(3.6; 33-45) and 43.3(2.6) [p<0.001]. PFP scores (cumulative), upper body function and endurance scores were improved with Genium compared with C-Leg at 9.1%(p=0.03), 8.7%(0.01) and 10.3%(0.04) respectively. Quality of Life: For quality of life, situational satisfaction favored Genium (p<0.001) which included subject's satisfaction with gait,…

A caminhada humana é um movimento importante utilizado pelo homem, porém extremamente complexo em relação aos mecanismos energéticos e mecânicos que geram este movimento. O custo energético é maior na caminhada de amputados quando comparada a caminhada de indivíduos sem restrições físicas. Variáveis mecânicas e energéticas de amputados não foram extensivamente estudadas. Nosso objetivo foi avaliar a influência de diferentes velocidades, no recovery, no custo de transporte (C), na eficiência mecânica (Eff), na transdução pendular (Rint), trabalho mecânico, na estabilidade dinâmica, bem como verificar a associação entre a estabilidade dinâmica com recovery, custo de transporte e eficiência mecânica. Participaram do estudo 10 indivíduos amputados transfemurais (com joelho hidráulico e pé em fibra de carbono). Foi realizada cinemetria 3D (quatro câmeras de vídeo) e simultaneamente a análise do consumo de oxigênio. Foram determinadas cinco velocidades de caminhada, após definir a velocidade auto selecionada. Além da velocidade auto selecionada foram definidas duas velocidades acima e abaixo das VAS. Para os dados de Recovery, custo de transporte, eficiência mecânica, transdução pendular, trabalho total, trabalho externo, travalho vertical, trabalho horizontal, trabalho interno e estabilidade dinâmica foram utilizadas rotinas desenvolvidas em Matlab®. A velocidade influencia nos parâmetros mecânicos e energéticos da caminhada de amputados transfemurais. Os maiores valores para: economia de caminhada, Recovery, transdução pendular, eficiência mecânica, trabalho mecânico interno e vertical, e estabilidade dinâmica foram obtidos na máxima velocidade de caminhada dos sujeitos. As correlações entre o coeficiente de variação do comprimento da passada e Recovery, custo de transporte e potência metabólica foram moderadas. Esses resultados são de grande relevância para a área clínica e ponderados durante o processo de reabilitação desses indivíduos.

The human walking is an important movement used by man, but extremely complex in relation to the energetic and mechanical mechanisms that generate this movement. The energy cost of gait is greater in amputees than in normal subjects. Mechanical and energetics variables in amputees have not been extensively studied. Our objective was to assess the influence of speed in recovery, cost of transport (C), mechanical efficiency (Eff), pendular transduction (Rint), mechanic parameters, dynamical stability, well as to verify agreement between dynamical stability with recovery, C, Eff and metabolic power. Materials and Methods: ten transfemoral amputees (with hydraulic knee and carbon fiber foot) were selected in the study. Simultaneously three-dimensional (3D) kinematics data (four cameras) and oxygen consumption were collected at five speeds, two above and two below self-select one. The Recovery, C, Eff, Rint, dynamical stability, were processed using Matlab software. Mechanics and energetics of amputee walking were influenced by speed. In maximal speed of amputee walking were reported…

▼ One of the main causes of above knee or transfemoral amputation (TFA) in the developed world is trauma to the limb. The number of people undergoing TFA due to limb trauma, particularly due to war injuries, has been increasing. Typically the trauma amputee population, including war-related amputees, are otherwise healthy, active and desire to return to employment and their usual lifestyle. Consequently there is a growing need to restore long-term mobility and limb function to this population. Traditionally transfemoral amputees are provided with an artificial or prosthetic leg that consists of a fabricated socket, knee joint mechanism and a prosthetic foot. Amputees have reported several problems related to the socket of their prosthetic limb. These include pain in the residual limb, poor socket fit, discomfort and poor mobility. Removing the socket from the prosthetic limb could eliminate or reduce these problems. A solution to this is the direct attachment of the prosthesis to the residual bone (femur) inside the residual limb. This technique has been used on a small population of transfemoral amputees since 1990. A threaded titanium implant is screwed in to the shaft of the femur and a second component connects between the implant and the prosthesis. A period of time is required to allow the implant to become fully attached to the bone, called osseointegration (OI), and be able to withstand applied load; then the prosthesis can be attached. The advantages of transfemoral osseointegration (TFOI) over conventional prosthetic sockets include better hip mobility, sitting comfort and prosthetic retention and fewer skin problems on the residual limb. However, due to the length of time required for OI to progress and to complete the rehabilitation exercises, it can take up to twelve months after implant insertion for an amputee to be able to load bear and to walk unaided. The long rehabilitation time is a significant disadvantage of TFOI and may be impeding the wider adoption of the technique. There is a need for a non-invasive method of assessing the degree of osseointegration between the bone and the implant. If such a method was capable of determining the progression of TFOI and assessing when the implant was able to withstand physiological load it could reduce the overall rehabilitation time. Vibration analysis has been suggested as a potential technique: it is a non destructive method of assessing the dynamic properties of a structure. Changes in the physical properties of a structure can be identified from changes in its dynamic properties. Consequently vibration analysis, both experimental and computational, has been used to assess bone fracture healing, prosthetic hip loosening and dental implant OI with varying degrees of success. More recently experimental vibration analysis has been used in TFOI. However further work is needed to assess the potential of the technique and fully characterise the femur-implant system. The overall aim of this study was to develop physical and computational models of the TFOI…

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…

▼ Traumatic injuries to the extremities are commonly observed in emergency room patients and military personnel in combat. Restoring high mobility and functionality is a primary goal post-injury, which may require the use of rehabilitative devices, surgical interventions, and rehabilitation therapies. The research detailed in this dissertation investigates specific elements of these approaches through the use of experimental study and modeling and simulation. In the first study, the influence of passive-dynamic ankle-foot orthosis bending axis on the gait performance of limb salvage subjects was investigated. Bending axis location was altered by fabricating customized orthosis components using additive manufacturing and was tested in a gait laboratory. Altering bending axis location did not result in large or consistent changes in gait measures, however subjects expressed strong preferences for bending axis condition and preference was strongly related to specific gait measures. This suggests that preference and comfort are important factors guiding the prescription of bending axis location. In the second study, musculoskeletal modeling was used to examine the influence of transfemoral amputation surgical techniques on muscle capacity to generate forces and moments about the hip. Muscle reattachment tension and stabilization were shown to be critical parameters for post-amputation capacity, which supports the use of myodesis stabilization (muscle is reattached directly to bone) in amputation procedures. In the third study, a forward dynamics simulation of transfemoral amputee gait was developed and used to examine individual muscle and prosthesis contributions to walking subtasks. The residual hip muscles, and intact ankle, knee, and hip muscles worked synergistically to provide body support, anteroposterior propulsion, mediolateral control, and leg swing. Increased contributions of contralateral muscles to ipsilateral subtasks as well as increased duration of specific muscle contributions were observed in comparison to non-amputee and transtibial amputee walking. These findings can be used to help develop targeted rehabilitation therapies and improve transfemoral amputee locomotion. Through elucidating the influence of PD-AFO bending axis on gait performance as well as the influence of transfemoral amputation surgical techniques on muscle capacity and function, this research provides a foundation for improved rehabilitation outcomes, and thus mobility for individuals who have experienced traumatic lower-limb injuries.

Although sitting is a large part of everyday life is the influence of the sitting positions and chair design on pressure and load distribution as well as comfort for transfemoral amputees quite unexplored. The aim of this study was therefore to examine this further. Two transfemorally amputated females (49 and 57 years old) participated in the study. Three positions were examined for each subject; sitting without foot support and sitting with the knee joints flexed 90◦ and 105◦. The pressure inside the socket was measured by two pressure sensors, placed distally and proximally on the posterior wall inside the socket. The lengthwise pressure distribution and the sidewise load distribution between the socket and the underlying material was measured by a pressure mat. In addition to this, the subjects answered a questionnaire regarding the subjective comfort for each position. The result showed that the pressure underneath the socket were higher distally than proximally without foot support. The pressure transferred proximally as the knee became more flexed. The most even load distribution sidewise was found when the subjects sat with their knees flexed 105 degrees. Sitting with the knees flexed 90◦ was ranked as the most comfortable position. No conclusion could be made regarding the pressure inside of the socket. Additionally, according to this study the level of comfort does not have any clear relation with the sidewise load distribution or the longitudinal pressure distribution.

En stor del av livet spenderas sittandes, men den påverkan som sittposition och stoldesign har på tryckfördelning och komfort för transfemoralt amputerade är ganska outforskat. Studien ämnar därför undersöka detta. Två transfemoralt amputerade kvinnor (49 och 57 år) medverkade i studien. Tre sittpositioner undersöktes för varje testperson; sittande utan fotstöd samt sittande med knäleden i 90◦ respektive 105◦ flexion. Trycket inuti hylsan mättes med hjälp av två trycksensorer, som placerades distalt och proximalt på den bakre hylsväggen. Tryckfördelningen i längsriktningen och lastfördelningen i sidled mellan hylsan och underlaget mättes med en tryckmatta. Förutom detta svarade testpersonerna även på ett frågeformulär angående den subjektiva komforten för varje position. Resultatet visade att trycket under hylsan var högre distalt än proximalt när inget fotstöd användes. Trycket förflyttades proximalt då knät böjdes. Den mest jämna lastfördelningen mellan sidorna påträffades när knät var flekterat 105◦. Enligt frågeformuläret var den mest bekväma positionen den med 90◦ i knäleden. Ingen slutsats kunde göras angående trycket inuit hylsan. Ingen tydlig relation kunde heller inte hittas mellan den subjektiva komforten och tryck- eller lastfördelningen.

▼ The aim of this project was to develop a methodological platform in order to advance our scientific understanding of the mechanisms of osseointegration. Screw-shaped, titanium implants, with different surface properties, were inserted in the rat tibia, or incubated in mono- or co-culture of human monocytes and MSCs. After different time points, the implant-adherent cells or the peri-implant bone were harvested and processed for different analyses. For in-vivo studies, qPCR, immunohistochemistry, histomorphometry, electron microscopy and removal torque analyses were used. In the in-vitro study, FACS, qPCR, ELISA and protein profiling were applied. Finally, qPCR was employed in a clinical study to analyse the abutment-adherent cells of osseointegrated fixtures. At the early time points in vivo, a higher gene expression of MSC recruitment and adhesion factors (CXCR4 and integrin-β1) was found in cells adhering to the oxidised compared to machined implant. This was corroborated by predominance of MSCs at the oxidised surface, as judged by immunohistochemistry and SEM. At the later time points, cells adhering to oxidised implants retained a higher expression of bone formation (ALP and OC) and bone remodelling (TRAP and CatK) genes. The qPCR findings correlated with histomorphometric, electron microscopy and removal torque measurements, revealing progressively increasing bone-implant contact and bone bonding and, as a result, an increase in the biomechanical stability of the oxidised implant. The enhanced RANKL/OPG expression ratio corresponded to the remodelling phase at the bone-implant interface. The qPCR analysis of FACS-sorted cells showed that the co-existence of monocytes and MSCs on the implant surface, in vitro, upregulates the gene expression of some cytokines in a cell-specific manner. The clinical study showed that bacterial colonisation was frequently detected on the skin, the abutment and in the bone canal. A higher expression of TNF-α was associated with positive cultures of S. aureus, whereas fixture loss was associated with lower expression of OC and IL-10. In conclusion, the present methodological platform enables detailed analyses of the events at the bone-implant interface. Employing this platform demonstrated that implant surface properties elicit a cellular and molecular cascade for rapid cell recruitment and enhanced bone formation and remodelling, which accelerates bone maturation and implant stability. Finally, the results of the thesis provide a first line of information on factors that could affect the performance of percutaneous implants.

▼ Review: Research examining trunk biomechanics in the transfemoral amputee population has only recently begun to include analysis of trunk muscle activity. Based on the absence of knee extensor muscles in the prosthetic limb, the muscles of the hip and trunk will demonstrate compensatory activity. This is an important area of research given that there is an increased incidence of low back pain among transfemoral amputees. Purpose: The overall purpose of this thesis was to explore movement compensations exhibited by unilateral transfemoral amputees throughout a series of activities of daily living, with a focus on trunk biomechanics. Rotational trunk stiffness, and spine and lower limb kinematics were recorded and used to identify areas of difficulty and/or risk of injury and low-back pain. Methods: Twelve total control participants and four amputee participants participated in this study. The tasks recorded included gait, step down, step up, sit-to-stand, and door pull. Lower limb and trunk angles, and trunk and hip muscle electromography were recorded for each participant, and these data were used to model 3-dimensional rotational trunk stiffness about the L4-L5 joint. These data, including individual muscles’ percent contribution to the overall stiffness, were compared between tasks and between subject groups. Results: During the gait task, amputees’ frontal plane stiffness was greater during prosthetic single support phase in the absence of a load-bearing cane. When stepping down, non-cane using amputees displayed a flexed trunk at impact, and only the microprocessor prosthesis displayed knee flexion after contact. The step up task resulted in greater lateral trunk bending and stiffness from the amputee group. The amputee participants also showed more sustained trunk stiffness throughout the sit-to-stand task, with a local peak at seat-off. Conclusions: The altered movement and stiffening patterns of the transfemoral amputees were in an effort to increase trunk stability and mitigate risk of injury. It was concluded that, during some tasks, an increased stiffness is required from amputees to perform the same movement as the control group. The most at-risk tasks are the step down and sit-to-stand tasks, though other tasks also displayed characteristics linked to low-back pain.

▼ Transfemoral amputees suffer the loss of the knee and ankle joints, as well as partial or complete loss of many of the lower extremity muscle groups involved in ambulation. Recent advances in lower limb prostheses have involved the design of active, powered prosthetic knee and ankle-foot components capable of generating knee and ankle torques similar to that of normal gait. The associated onboard motors, conditioning/processing, and battery units of these active components result in increased mass of the respective prosthesis. While not an issue during stance, this increased mass of the prosthesis affects swing. The goal of this study is to develop and validate mathematical models of the transfemoral residual limb and prosthesis, expand these models to include an active ankle-foot, and investigate counter-mass magnitude(s) and location(s) via model optimization that might improve kinematic symmetry during swing. Single- (thigh only, shank only) and multi-segment (combined thigh and shank) optimization of counter-mass magnitudes and locations indicated that a 2.0 kg counter-mass added 8 cm distal and 10 cm posterior to the distal end of knee unit within the shank segment approximated knee kinematics of able-bodied subjects. This location, however, induced artificial hip torques that reduced hip flexion during swing. While such a counter-mass location and magnitude demonstrated theoretical potential, this location is not clinically realistic; mass can only be added within the prosthesis, distal to the residual limb. Clinically realistic counter-masses must also keep the total prosthetic mass to less than 5 kg; greater mass requires supplemental prosthetic suspension, would likely increase energy expenditure during ambulation, and contribute to increased likelihood of fatigue even with active prosthetic components. The ability to simulate the effects of active prosthetic components inclusive of varying placement of battery and signal conditioning units may advance the design of active prostheses that will minimize kinematic asymmetry and result in greater patient acceptance.
