Purpose: The aim of this study was to investigate the association between functional ability and physical activity (PA) in individuals with transtibial amputations.

Methods: Twenty participants with unilateral transtibial amputation were recruited from outpatient prosthetic fitting clinics. Subjects completed the amputee mobility predictor (AMP), the L-Test, timed up and go (TUG), 2-minute walk test (TMWT), and self-reported activity restrictions questionnaire (Prosthesis Evaluation Questionnaire-Mobility Subscale). The subject's PA was monitored continuously for 7 days using a body-worn PA monitor. Descriptive statistics, comparison of mean values, and analysis of associations were performed with significance set at P < .05.

Results: Data from 19 subjects were used for analysis. Descriptive analysis indicated that the participants spent on average 19.7 (SD = 0.5) hours per day laying/sitting, 3.5 (SD = 0.4) hours standing, 0.77 (SD = 0.07) hours stepping, and walked an average of 3145 (SD = 378) steps/day. There was a moderate to good correlation between the AMP and the average steps/day (r = 0.535, P = .009) and a fair correlation between the TMWT, the TUG, and steps per day (r = 0.404 and r = −0.442, respectively, P < .05).

Conclusions: Individuals with transtibial amputations on average recorded 3145 steps/day, placing them in the sedentary category. The number of steps per day had a moderate to good correlation with the AMP and a fair correlation with the TUG and TMWT.
