Abstract

Background. Hip osteoarthritis (OA) is a common musculoskeletal condition affecting older individuals. Clinical balance tests are frequently used to assess standing balance in these people. There is insufficient information regarding the reliability of these tests. Objective. The aim of this study was to estimate reliability and measurement error of 4 common clinical standing balance tests in people with hip OA. Design. A prospective study was conducted with repeated measures between 2 independent raters within 1 session and within 1 rater over a 1-week interval. Methods. Thirty people with hip OA were evaluated. Reliability was estimated for the Four-Square Step Test, Step Test, Functional ..
