Exercise in Patients With Osteoarthritis of the Hip
- Conditions
- Hip Osteoarthritis
- Interventions
- Procedure: Nordic WalkingProcedure: Unsupervised home based exerciseProcedure: Strength training
- Registration Number
- NCT01387867
- Lead Sponsor
- Bispebjerg Hospital
- Brief Summary
According to Danish and international guidelines the recommended first-line of management for people with osteoarthritis consist of exercise, education, analgesic medication, and, if necessary, weight reduction. It is well documented that exercise has a positive effect on pain and physical function in patients with knee OA, but the effect of exercise on hip OA is sparsely investigated.
Aim of the study: To investigate the effects of 1) strength training, and 2) Nordic Walking, and 3) unsupervised home based exercise on muscle function, endurance, pain level, physical activity, and health related quality of life in patients with osteoarthritis of the hip.
The effects of exercise on muscle mass and the mechanisms behind the osteoarthritis, i.e., disease activity, inflammation, and cartilage degradation, are investigated in a subgroup (n=45) of the participants.
Study hypotheses: Strength training will have a greater effect on physical function and muscle strength than Nordic Walking and home based exercise; 2) Nordic Walking will have a greater effect on endurance than strength training and unsupervised home based exercise; 3) Strength training and Nordic Walking will have a greater effect on pain level and health related quality of life than unsupervised home based exercise.

Change from Baseline in self-reported physical activity at 2, 4 and 12 months Baseline, 2, 4, and 12 months PASE (Physical Activity Scale for the Elderly) and a question from Copenhagen City Heart Study
Change from Baseline in health related quality of life at 2, 4 and 12 months Baseline, 2, 4, and 12 months SF-36
