Transfemoral Biomechanics

To develop an ultrasound system to monitor the dynamic movement of the residual femur in a transfemoral socket, the transfemoral biomechanics plays an important role. Several factors determine the specific kinematics and kinetics of transfemoral amputee gait cycle. Some of the factors influencing the kinematics and the kinetics are stump length and range, type of prosthetic components like socket, alignment of the prosthesis, quality of the amputation surgery, condition of the intact limb, other amputee specific factors like age, cause of amputation, pain and so on \cite{kobayashi2013effect}. The basic goals of fitting and aligning prostheses for transfemoral amputees are comfort and function. However, obtaining these goals is more challenging
