The human ankle varies impedance and delivers net positive work during the stance period of walking. In contrast, commercially available ankle-foot prostheses are passive during stance, causing many clinical problems for transtibial amputees, including non-symmetric gait patterns, higher gait metabolism, and poorer shock absorption. In this investigation, we develop and evaluate a myoelectric-d...

A unilateral transtibial amputation causes a disruption to the musculoskeletal system, which results in asymmetrical biomechanics. The current study aimed to assess the movement asymmetry and compensations that occur as a consequence of an amputation when performing a countermovement vertical jump. Six unilateral transtibial amputees and 10 able-bodied (AB) participants completed 10 maximal ver...

Pain and pain-related interference with physical function have not been thoroughly studied in individuals who have undergone knee-disarticulation amputations. The principal aim of this study was to determine whether individuals with knee-disarticulation amputations have worse pain and pain-related interference with physical function than do individuals with transtibial or transfemoral amputatio...

Abstract Background Powered prosthetic ankles provide battery-powered mechanical push-off, with the aim of reducing metabolic demands walking for people transtibial amputations. The efficacy powered has been shown in active, high functioning individuals amputation, but is less clear other populations. Additionally, it unclear how use a prosthesis influences everyday physical activity and mobili...

As a whole, human sprinting seems to be completely periodic and symmetrical motion. This view is changed when person runs with running-specific prosthesis after unilateral amputation. The aim of our study investigate differences similarities between below-knee amputee non-amputee sprinters—especially regard whether asymmetry distracting factor for sprint performance. We established three-dimens...
