Physical Performance-Based Outcome Measures in Total Hip Arthroplasty Patients: COSMIN-Based Systematic Review

Abstract

Aims: The purpose of the present review was to conduct a COnsensus‐based Standards for the selection of health Measurement Instruments (COSMIN)-based analysis of the physical performance tests in patients with total hip arthroplasty (THA). Method: Databases were searched on February 2021 in “PubMed, Scopus, and Web of Science” literature databases. The “COSMIN tool” was chosen to determine the quality and potential bias of the enclosed papers. “Narrative synthesis” was conducted due to the heterogenous data of the articles. Results: Twelve publications were enrolled in the review. Seven studies analyzed “intra-rater reliability,” seven study “validity,” six study “measurement error,” one study “inter-rater reliability,” and one study presented “responsiveness analysis.” Conclusion: This review proved the psychometric properties of performances tests in THA, regarding COSMIN guidelines. The analysis result of studies yielded a “good” or “fair” quality design. Most of the studies (7) focused on gait-based test. Further studies should focus on “inter-rater reliability, responsiveness, and floor-ceiling effect”.
