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...
Aims Patients with recurrent anterior dislocation of the shoulder commonly have an osseous defect glenoid. Once reaches a critical size, stability may be restored by bone grafting. The size this under non-physiological loading conditions has previously been identified as 20% length As is load-dependent, higher joint forces leading to loss stability, aim study was determine that leads further instability physiological despite Bankart repair. and Methods Two finite element (FE) models were...
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...
Individuals with transfemoral lower limb amputations walk adapted gait. These kinetic and kinematic compensatory strategies will manifest as differences in muscle recruitment patterns. It is important to characterize these understand the reduced endurance, functionality, progression of co-morbidities this population. This study aims during gait highly functional individuals traumatic donning state-of-the-art prosthetics compared able-bodied controls. Inverse dynamic static optimisation...
Abstract Background Direct skeletal fixation, a surgical technique enabling the attachment of an external prosthesis directly to bone through percutaneous implant, offers enticing solution for patients with lower limb amputations facing socket-related issues. However, understanding its impact on musculoskeletal function remains limited. Methods This study compares pre- and 1-year post-osseointegration surgery outcomes, focusing patient-reported measures system during level-ground walking....
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...
