Tai Chi or Hydrotherapy for People With Osteoarthritis of the Hip(s) or Knee(s)

Not Applicable

• Conditions: Osteoarthritis, Hip; Osteoarthritis, Knee

• Registration Number: NCT00123994
• Lead Sponsor: St George Hospital, Australia

Brief Summary

The aim of this study is to determine, in the framework of a randomized controlled clinical trial, whether Tai Chi can affect measurable improvements in self-reported outcomes such as pain, physical function and psychological well-being in people with osteoarthritis (OA) mainly affecting the hips or knees. The effectiveness of Tai Chi will be compared with both a non-intervention control group as well as with a formal exercise program, hydrotherapy. Hydrotherapy has long been considered an effective intervention for people with chronic OA although scientific evidence is weak at present. The main study hypotheses are that Tai Chi or hydrotherapy can significantly decrease pain and physical limitations; improve health-related quality of life; and promote psychological well being in patients with OA of the hip(s) or knee(s); and that Tai Chi and hydrotherapy are of equal efficacy.

Detailed Description

A single blinded randomized controlled clinical trial with 3 allocation groups:

* Tai Chi: maximum 15 people per group, twice weekly, 12 weeks.

* Hydrotherapy: maximum 15 people per group, twice weekly, 12 weeks.

* Control: 12 weeks waiting time prior to allocation to active intervention.

A specially designed Tai Chi program (Tai Chi for Arthritis, Paul Lam) will be provided in a community setting by trained instructors. Hydrotherapy sessions will be held at the St. George Hospital under supervision of registered physiotherapists with rheumatology and hydrotherapy experience.

Outcomes will be measured twice: 12 and 24 weeks after randomisation.
