Medial Wedge Insoles to Improve Gait in Persons After Total Hip Replacement - Randomized Control Trial

The study will test the hypothesis, that the use of medial wedge insoles in people participating in comprehensive rehabilitation between 1-6 months after total hip replacement, and not having a varus deformity of the knee or symptomatic arthrosis of the medial knee compartment, will improve patient's functioning, the symmetry of gait and stance compared to persons using sham insoles.The participants will undergo a 6-week program of in-patient rehabilitation aimed at: pharmacologic and non-pharmacologic pain management, improvement of vascular function, cardiopulmonary function, functions of skeletal muscles, range of motion and stability of peripheral joints, gait function, body position. The rehabilitation program will also address individual needs with psychotherapy and vocational therapy.The study will help to identify correlations between gait parameter change and functional improvement during the rehabilitation following THR.Study participants will be provided with individually made corrective medial wedge insoles or sham insoles and instructed to use them during gait training and everyday activities.Functional parameters will be examined at the study entry, at the end of 6 weeks of intervention, and 6 weeks following discharge.
