Hakkinen, A., Sokka, T., Lietsalmi, A., et al. (2003). Effects of dynamic strength training on physical function, Valpar 9 work sample test, and working capacity in patients with recent-onset rheumatoid arthritis. Arthritis & Rheumatism, 49(1), 71-77.

Purpose: Individuals with rheumatoid arthritis often experience a decline in physical function. This decline is often associated with inflammation, pain, fatigue, muscle weakness, atrophy, and limited range of motion, and can affect a person's ability to work and remain independent. The purpose of this study was to examine a 24-month strength-training program on functional ability and pain level.

Results: Both functional ability and pain tolerance improved.
