Exercise in the treatment of osteoarthritis

Abstract

Few medical professionals would dispute the obvious health benefits afforded by regular exercise if pursued judiciously and in moderation. Cardiovascular disease, hypertension, osteoporosis, diabetes, depression, and fibromyalgia are a few of the many disorders in which exercise plays a key role in management. Less well-appreciated until recently is the beneficial effect exercise may have in the treatment of osteoarthritis (OA). Previously, rest and inactivity seemed to be the prevailing treatment strategy until it was recognized that this approach was ineffective and contributed further to the patient’s disability and loss of function. New trial data support the value of physical exercise whether it involves aerobic or resistance-type training. The studies are not without statistical and methodologic imperfections. Still, the evidence favoring an exercise intervention as part of the OA treatment plan is impressive. It remains for the clinician to select an appropriate exercise routine that meets the strength, balance, flexibility, and aerobic needs of the patient. The clinician then monitors and evaluates the patient’s response to this activity with the same exactness used in following pharmacologic therapy.
