Biomechanical comparison of SACH and Dynamic-Response feet in transtibial amputee during running: A systematic review

An suitable prosthesis may have contributed effectively to amputee’s ability to accomplish activities. According to the search field and empirical evidence Dynamic-Response feet and SACH feet are common prosthetic components used. Consequently, the purpose of the present review was to compare the biomechanical studies of running with SACH and Dynamic-Response according to main parameters in running analysis.
An electronical search was done in PubMed, Ovid and Science Direct without time limitation. The abstract and title of papers were reviewed based on selected Criteria. The quality of the papers was evaluated based on Downs and Black tool. Key words include “Amputee”, “Dynamic-Response”, “energy-storing”, “SACH”, and “Running” were selected for the search.
Based on the search keywords, 722 articles were found. Regarding the selection criteria, 4 articles were chosen. Amount of biomechanical studies have been found is not too enough to distinguish preference between SACH feet and Dynamic-Response feet.
The biomechanical preference among SACH feet and Dynamic-Response during running feet is not cleared. In addition, various dependent variables among studies has made harder a comprehensive conclusion. So further studies with similar topics, measurement tools and outcome measures are recommended.
