Background: Passive prosthetic knees incorporate extension assist mechanisms to enhance the swing phase of gait cycle for persons with above/through-knee amputations. In conventional polycentric using a 4-bar linkage, mechanism connects one bars body prosthesis. However, this design introduces singularity in spring action delivery, causing push knee into flexion beyond certain angle. contrast, an that links upper and lower parts eliminate feature, ensuring is pushed toward throughout full...
Amputation of a major limb, and the subsequent return to movement with prosthesis, requires development compensatory strategies account for loss. Such strategies, over time, lead regional muscle atrophy hypertrophy through chronic under or overuse muscles compared uninjured individuals. The aim this study was quantify lower limb parameters persons transtibial transfemoral amputations using high resolution MRI ascertain volume determine regression equations predicting femur- tibia-length,...
Customisation of musculoskeletal modelling using magnetic resonance imaging (MRI) significantly improves the model accuracy, but process is time consuming and computationally intensive. This study hypothesizes that linear scaling to a lower limb amputee with anthropometric similarity can accurately predict muscle joint contact forces.An MRI-based anatomical atlas, comprising 18 trans-femoral through-knee traumatic models, developed. Gait data, 10-camera motion capture system two force...
Introduction: Due to loss in musculoskeletal capacity, there is an increased burden on the residual limbs of bilateral transfemoral and through-knee persons with limb loss. This reduced capacity associated cost walking that detrimental functionality. Compensatory gait strategies are adopted by this population. However, how these relate specific muscle recruitment not known. The primary aim study characterize during secondary assess whether measured kinematics can be actuated when endurance...
Abstract Background Currently, there is little available in-depth analysis of the biomechanical effect different prostheses on musculoskeletal system function and residual limb internal loading for persons with bilateral transfemoral/through-knee amputations (BTF). Commercially BTF include full-length articulated (microprocessor-controlled prosthetic knees dynamic response feet) foreshortened non-articulated stubby prostheses. This study aims to assess compare during gait these two types...
