Comparative Effect between Silesian Suspension and Total Elastic Suspension on GRF Loading in Subjects with Trans-Femoral Prosthesis: A Biomechanical Study
Background: The major function of all Suspension systems is Prosthesis retention. The suspension system prevents rotation, translation and vertical movement of the prosthesis in relation to the residual limb. The Silesian suspension and TES system that are commonly prescribed for Transfemoral amputees are believed to provide a better suspension. Nevertheless, their effect on Transfemoral amputees’ gait performance has not yet been fully investigated. The main intention of this study was to understand the potential effects of the Silesian suspension and TES systems on Transfemoral amputees on gait kinetics. Aim & Objective: To find out the effect of two types of suspension system on Gait Kinetics in subject with unilateral transfemoral amputee. Study Design: Two group post-test Comparative Experimental study design. (Quasi Experimental). Methods: 30 subjects with two different suspension systems such as Silesian suspension (Group-A) and Total Elastic Suspension (Group-B) was included in this study by convenient sampling method. All subjects walked with Endo skeletal design Trans femoral Prostheses gait training given called after 3 weeks. After that data regarding gait kinetics parameters was evaluated by Kistler Force Plate in dynamic position. Result: The results revealed that there is significant difference in gait kinetics parameters that GRF (Fx) mean shows no significantly difference between Group-A and Group-B (p= 0.582), GRF (Fy) mean shows non-significantly difference between Group-A and Group B (p=0.163) and GRF (Fz) mean shows non-significantly difference between Group-A and Group-B. Conclusion: The findings concluded that the study support the hypothesis that there were significant difference with two different suspension system on kinetic gait parameters.
