Does the Total Hip Replacement Impact of Postural Stability?
In Brief
A clinical study evaluating Static Posturography and One-leg standing test (OLS) for Total Hip Replacement. Completed, enrolled 60 participants.
Detailed Summary
Total hip replacement (THR) is the procedure which can improve the quality of life in patients with osteoarthritis. However, deficits in static stability and impairment of the lower limb efficiency can be observed even several months after procedure. The aim of this study was to investigate the static balance of the standing position in patients treated by THR.

Interventions
The balance platform (Good Balance by Metitur) and one leg standing test (OLS) were used to assess the static balance. OLS test was performed on left and right foot separately. The static posturography was performed with several various positions of feet. Position : normal standing with eyes open and eyes closed - an upright standing with feet placed parallel 20 cm apart for 30 s. Position: tandem - a stance with one foot placed ahead of the other for 10 s. Position: second form of tandem - a stance with one foot placed ahead of the other with feet placed on both sides of the line dividing platform to two parts for 20s. Position: one leg standing: stance on the one leg for 5 s.
During the one-leg standing test (OLS) the time of maintain this position by the patients was measured. The placement of the limbs was the same as in the case of the balance platform test. Subjects performed 3 trials on each lower limb. Time ended when subject either: loosed balance and touched raised foot the floor, moved supporting leg on the ground, a significant loss of balance or a maximum of 60 s had elapsed. Results achieved by the subjects after THR on both operated (OLS-O) and non operated limbs (OLS-N) were compared with the index of the control group (OLS-C: mean result of the tests performed on the left and right legs).
