Exercise and physical functioning in osteoarthritis

Recent research has shown that neuromuscular factors (such as muscle strength, joint laxity) and behavioral factors (such as avoidance of activity, depressed mood) predict pain and disability in OA. Furthermore, exercise and physical activity are among the dominant interventions aiming at reducing pain and disability, and innovative interventions targeting neuromuscular and behavioral interventions have been recently developed. This research has been published as separate papers, with the result that the field is in need of an integrative contextual review that puts the research into theoretical perspective.
