Comparison of intervention group to control group, and changes seen in clinical measures. Pain is the level of pain measured on the visual analog scale (VAS). Stiffness is the level of stiffness measured on the VAS. “Barriers” is the perceptual barriers to exercise as measured by the Exercise Benefits and Barriers Scale (EBBS). EBBS indicates the overall perception of exercise. FSS is the level of fatigue as measured by the Fatigue Severity Scale.
