This study measured spatio temporal parameters (STP) and their symmetry index (SI) in order to evaluate the differential effect on the gait pattern of individuals with unilateral transtibial amputations when using two different prostheses. Twelve individuals with transtibial amputations walked on level ground using an Energy Storage and Return (ESAR) prosthesis with fixed ankle and a prosthetic foot with adaptive ankle (PFAA). The STP were measured in the prosthetic and sound limbs and the symmetry index for each parameter was calculated afterwards. The results showed no statistically significant differences between the prostheses for the STP measured, and this was the case both for the prosthetic and sound limbs. Similarly, the SI did not reflect statistically significant differences when the different prostheses were used. Thus, the results suggest that the STP studied and their SI may not reflect differences when evaluating ESAR versus PFAA prostheses in the conditions proposed in this study.
