Comparison of high and low intensity training in well controlled rheumatoid arthritis. Results of a randomised clinical trial.

Objective: To investigate the benefit of intensive dynamic exercises in comparison to range of motion (ROM) and isometric exercises in rheumatoid arthritis.

Methods: 100 consecutive rheumatoid arthritis patients on stable medication were randomly assigned to (1) intensive dynamic group exercises which included full weight bearing exercises and conditioning exercises on a stationary bicycle while the heart rate was maintained at 70-85% of the age predicted maximum heart rate, (2) range of motion (ROM) exercises and isometric exercises in a group, (3) individual isometric and ROM exercises, and (4) home instructions for isometric and ROM exercises. Variables of physical condition, muscle strength, joint mobility, daily functioning (HAQ), and disease activity were assessed before and after the 12 week exercise course, and 12 weeks thereafter.
