Reliability of the 9-step stair climb test in people with total hip arthroplasty (original) (raw)

Abstract

Introduction: Measurement of treatment outcomes is a critical component of clinical practice for people with total hip arthroplasty (THA). 9-step Stair Climbing test (SCT) is one of the most used SCT for people with osteoarthritis. However, reliability of 9-step SCT has not been shown in people with THA. Objectives: The aim is to investigate the test-retest reliability of 9-step SCT in people with THA. Methods: 37 patients with THA participated in this study. Patients performed twice trials for 9-step SCT on the same day. Between the first and second trials, patients waited for an hour on sitting positionin order to prevent fatigue. To assess reliability, intra-class correlation coefficient [ICC (2,1)], standard error of measurement (SEM), smallest real difference at the 95% confidence level (SRD95) were calculated. Results: The average time for the first trial was15.14 ± 7.17 seconds and 15.05 ± 7.02 seconds for the second trial. There was no significant difference between the tria...
