| description | <p><strong>Objective</strong></p> <p>To determine the validity and inter- and intra-rater reliability of the Four Square Step Test (FSST) in assessing gait performance, balance and physical function for patients with hip osteoarthritis before and after total hip replacement (THR).</p> <p><strong>Design</strong></p> <p>Observational, repeated measures.</p> <p><strong>Setting</strong></p> <p>A specialist orthopaedic hospital.</p> <p><strong>Participants</strong></p> <p>Fifty-eight participants with moderate to severe hip osteoarthritis scheduled to receive primary hip replacement within 4 months from recruitment.</p> <p><strong>Main outcome measure</strong></p> <p>Time to complete the FSST, time and steps to complete the Figure of 8 Walk Test (F8W) and Berg Balance Scale score (BBS).</p> <p><strong>Results</strong></p> <p>The Bland and Altman limits of agreement for intra-rater measurements of the FSST were −3.2 s to 3.5 seconds before THR and −1.5 to 2.0 seconds after THR. Limits of agreement for two different raters were −2.2 to 3.4 seconds, all with small mean differences indicating little bias between raters or replications. Concurrent validity was assessed, and the FSST correlated highly with the F8W (r = 0.7, P < 0.001) and moderately with the BBS (r = 0.6, P < 0.001). Only one participant was rated as being at moderate risk of falls on the BBS, with the other participants scoring low; only one participant failed to complete the F8W. This is in contrast to the FSST, which 21 people failed to complete pre-operatively.</p> <p><strong>Conclusions</strong></p> <p>The FSST is a valid and reliable measure of multi-directional stepping speed and balance, giving a more informative measure of gait performance than the F8W and BBS, and is feasible for use in a clinical population of patients both before and after THR.</p> |
