We examined the application of outcome measures to determine changes in function
caused by standardized functional prosthetic gait training and the use of four
different prosthetic feet in people with unilateral transtibial limb loss. Two
self-report measures (Prosthetic Evaluation Questionnaire-Mobility Scale [PEQ-13]
and Locomotor Capabilities Index [LCI]), and three performance-based measures
(Amputee Mobility Predictor with a prosthesis [AMPPRO], 6-minute walk test [6MWT]
and step activity monitor [SAM]) were used. Ten people with unilateral
transtibial limb loss, five with peripheral vascular disease (PVD) and five
without PVD, completed testing. Subjects were tested at baseline and after
receiving training with their existing prosthesis and with the study socket and
four prosthetic feet, i.e., SACH (solid ankle cushion heel), SAFE (stationary
attachment flexible endoskeletal), Talux, and Proprio feet, over 8 to 10 weeks.
Training was administered between testing sessions. No differences were detected
by the PEQ-13, LCI, 6MWT, or SAM following training and after fitting with test
feet. The AMPPRO demonstrated differences following training with the existing
prosthesis in the PVD group and between selected feet from baseline testing ( p
</= 0.05). Significant differences were found between the PVD and the non-PVD
groups (p </= 0.05) in the AMPPRO and 6MWT when using the Proprio foot.
Self-report measures were unable to detect differences between prosthetic feet.
