Purpose:
The aim of our study was to investigate the relationship between self-reported and performance-based tests in the assessment of patients with total hip arthroplasty (THA).
Methods:
Ninety four patients (35 males, 59 females) were included in the study with mean age 57.1 ± 14.6 years. Patients performed four performance tests (Timed “Up & Go” Test, Sit to Stand Test, Self-paced Walk Test and Stair Test) and two self-reported measurements (Harris Hip Score [HHS] and SF-36 [36-Item Short Form Health Survey]) were preferred to assess patients.
Results:
There were varying correlations between performance tests and subscales of the SF-36 including physical function, energy/fatigue, pain, general health. Strong correlation was found between HHS and Timed “Up and Go”(r = −0.59, p < 0.001), self-paced walk test (r = −0.58, p < 0.001). Moderate correlation was found between HHS and sit to stand test (r = −0.406, p < 0.001), stair test (r = 0.32, p < 0.001).
Conclusions:
There were especially moderate-to-strong correlations between self-reported measurements and performance-based tests in the evaluation of patients with THA. Therefore, outcomes assessment after THA may include self-reported measurements or performance-based tests.
