Determining the feasibility of implementing a new concept to
objectively evaluate actual functional abilities of transfemoral amputees into a
new measuring tool called "Assessment of Daily Activity Performance in
Transfemoral amputees" (ADAPT). SUBJECTS: Study 1 comprised two groups of 10
participants, age range 19-72 years. One group used microprocessor-controlled
knee joints and the other group used mechanically controlled knee joints. Study 2
comprised 20 participants, age range 31-68 years. METHODS: Two versions of ADAPT
were assessed in the separate studies. In study 1 performance times on version 1
of ADAPT were compared between groups. In study 2 participants completed version
2 of ADAPT twice with a 1 h rest between trials. The Locomotor Capabilities Index
was administered. Reliability was determined by calculating correlation
coefficients and by Bland-Altman analyses. RESULTS: In study 1, ADAPT version 1
proved to be sensitive in detecting differences in performance between groups. In
study 2, 75% of all correlation coefficients exceeded 0.90 in version 2 of ADAPT.
Bland-Altman analyses showed high test-retest agreement. CONCLUSION: It is
feasible to reliably assess actual functional abilities of transfemoral amputees
using standardized simulations of daily activities. This ADAPT concept is able to
differentiate between different functional performance levels.
