- Abstract
Lower limb amputees face significant challenges in day-to-day life for locomotion. A prosthetic foot is used to restore mobility. The push-off effect from the prosthetic foot plays a vital role as it reduces gait asymmetry and sound limb loading. In the present work, four prosthetic foot, two conventional prosthetic foot (Jaipur foot and Ranger foot) and two energy-storing and return prosthetic foot (Nylon foot and Carbon fibre foot) are investigated for gait parameters of the unilateral transtibial amputee. Also, a novel wearable setup is used to acquire the amputee data. It comprises of two rotary potentiometers at the knee joint and two wearable slippers with four force sensitive resistor sensors on each. The gait parameters investigated in this study are the range of motion (ROM) of the knee joint, loading force on limbs, spatial and temporal gait parameters. Stability analysis between amputated and sound limbs is analyzed by measuring gait symmetry for gait parameters. Also, the coefficient of variation is calculated to see how gait parameters vary with the change of prosthetic foot. ROM symmetry and loading force symmetry is obtained maximum for Carbon fibre foot whereas minimum ROM symmetry is observed for Ranger foot. Furthermore, Carbon fibre foot attains maximum loading force symmetry of 0.98 indicating maximum push-off among all the four selected foot.
