title: Feasibility of a new concept for measuring actual functional performance in daily life of transfemoral amputees.
abstract: OBJECTIVE
  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).
  
  
  METHODS
  Study 1: cross-sectional design. Study 2: repeated measures design.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
