Exercise Therapy and Patient Education for Individuals With Hip Osteoarthritis. Long-term Follow-up.

Summary

The purpose of this study is to evaluate the long term effect of exercise therapy and patient education compared to patient education only in individuals with hip OA, and to evaluate predictive factors for changes in hip osteoarthritis both clinically and on x-ray.

Main hypothesis H01: There are no significant long term ( 2 years) differences in hip function, quality of life, physical function and radiological changes between those individuals who went through a patient education program and a 12 week exercise therapy program compared to patient education program only.

Material and Methods:

109 patients with radiographically verified hip OA are included in the randomized controlled trial; randomized to 12 week exercise therapy program and patient education (n=55) and patient education program only (n=54).

Data will be collected 2 years after completed intervention period in the original RCT, and 6 months and 2 years postoperatively for those patients who have undergone total hip arthroplasty.

The main outcome is:

The Disease Specific WOMAC-Index.

Secondary outcome measures are:

Hip X-ray, SF-36v2 (quality of life),PASE (activity score), Self-efficacy for pain, isokinetic muscle strength tests, 6 minute walk test, Åstrand's bike test, range of motion.

Status:

This study is a prolongation of an on-going RCT (3a-2005-NAR). The inclusion, intervention and follow-ups including 1 year follow-up is completed. 2 year post-intervention follow-up will be completed in 2010, 2 year follow-up postoperative for patients undergoing total hip artroplasty will continue throughout 2011.

The study will be carried out: NAR-Orthopedic Centre, Ullevaal University Hospital.

Conditions

• Hip Osteoarthritis

Interventions

OTHER

A 12 week exercise therapy program and patient education.

The exercise protocol includes exercises from former studies on comparable patient populations. The intensity of the strength- and flexibility exercises meets the American College of Sports Medicine's (ACSM) recommendations for developing and maintaining muscular fitness in adults.Patients will be required to exercise for 60 minutes, three days a week for 12 weeks. Patient's attendance to the exercise program (compliance) will be registered by the physical therapists. All patients included in the study will receive two individual and three small-group (6-7 patients) sessions lasting one hour each time.

OTHER

Patient education

All patients included in the study will receive two individual and three small-group (6-7 patients) sessions lasting one hour each time.
