Inter-Rater Reliability and Validity of the Stair Ascend/Descend Test in Individuals With Total Knee Arthroplasty

摘要

Objective1) To determine the inter-rater reliability and measurement error of a 11-step stair ascend/descend test (STTotal-11) and stair up (ascend) test (STUp-11); 2) to seek evidence for the STTotal-11 and STUp-11 as valid measures of physical function by determining if they relate to measures of physical function and do not relate to measures not of physical function; and 3) to explore if the STTotal-11 and STUp-11 scores relate to lower extremity muscle weakness and knee range of motion (ROM) in individuals with total knee arthroplasty (TKA).
