On balance of the limited evidence , the 40 m self-paced test was the best rated walk test , the 30 s-chair st and test and timed up and go test were the best rated sit to st and tests , and the Stratford battery , Physical Activity Restrictions and Functional Assessment System were the best rated multi-activity measures .
OBJECTIVES To systematic ally review the measurement properties of performance-based measures to assess physical function in people with hip and /or knee osteoarthritis ( OA ) .
A comparison of 3 methodological approaches to defining major clinically important improvement of 4 performance measures in patients with hip osteoarthritis.
STUDY DESIGN Prospect i ve cohort study . OBJECTIVES To establish the major clinical ly important improvement ( MCII ) of the timed up- and -go test ( TUG ) , 40-meter self-paced walk test ( 40-m SPWT ) , 30-second chair st and ( 30 CST ) , and a 20-cm step test in patients with hip osteoarthritis ( OA ) undergoing physiotherapy treatment . As a secondary aim , a comparison of methods was employed to evaluate the effect of method on the reported MCII . BACKGROUND Minimal clinical ly important difference scores are commonly used by rehabilitation professionals to determine patient response following treatment . A gold st and ard for calculating MCII has yet to be determined , which has result ed in problems of interpretation due to varied results . METHODS As part of a r and omized controlled trial , 65 patients were r and omized into a physiotherapy treatment group for hip OA , in which they completed 4 physical performance measures at baseline and 9 weeks . Upon completion of physiotherapy , patients assessed their response to treatment on a 15-point global rating of change scale ( GRCS ) . MCII was estimated using 3 variations of an anchor-based method , based on the patient 's opinion . RESULTS A comparison of 3 methods result ed in the following change scores being best associated with our definition of MCII : a reduction equal to or greater than 0.8 , 1.4 , and 1.2 seconds for the TUG ; an increase equal to or greater than 0.2 , 0.3 , and 0.2 m/s for the 40-m SPWT ; an increase equal to or greater than 2.0 , 2.6 , and 2.1 repetitions for the 30 CST ; an increase equal to or greater than 5.0 , 12.8 , and 16.4 steps for the 20-cm step test . CONCLUSION The variation in methods provided very different results . This illustrates the importance of comparing method ologies and reporting a range of values associated with the MCII , as such values vary , depending upon the methodology chosen
