【 摘 要 】

BackgroundTotal hip replacement (THR) is a procedure which can improve the quality of life in patients with osteoarthritis. However, deficits in static stability and impairment of lower limb efficiency can be observed even several months after the procedure. The aim of this study was to investigate the static balance of the standing position in patients treated by THR.MethodsThe study included 30 THR patients and 30 healthy subjects. The subjects were examined once. A Metitur balance platform and a one-leg standing (OLS) test were used to assess the static balance. The tests on the balance platform were performed in several positions with different foot placement, such as normal standing, eyes open (NS EO) and eyes closed (NS EC) positions, tandem position (TP), the second form of tandem position (2TP) and one-leg standing position (1 L).ResultsSignificant imbalance in the sagittal plane during normal standing EO and EC positions were found in the THR group. No significant differences in the measured parameters were found during tests in tandem, the second form of tandem and one-leg standing positions in the groups. The mean time of standing on the operated limb in the THR group during the OLS test was significantly shorter than that in the control group.ConclusionsDeficits in static balance may occur in THR patients even a long time after the procedure. The test performed in the NS position is sufficient to assess the balance. The rehabilitation protocols currently used after THR should include postural stability exercises.Trial registration numberTrial registry: NCT03218267. 12 July 2017 (retrospectively registered).
