Osteoarthritis typically occurs in the hands, knees, spine and hips affecting a multitude of joints. Those affected with OA will typically complain of symptoms of stiffness, low-grade inflammation and pain. This stiffness and pain are most prevalent in the morning which improves with activity and as the day progresses.

The cause of OA involves a combination of mechanical, cellular and biochemical changes. The processes involves changes in the composition and mechanical properties of the articular cartilage. Cartilage is comprised of water, collagen and proteoglycans. In healthy cartilage, there is continual remodeling that occurs as chrondocytes (cartilaginous cells) replace macromolecules that are lost through degradation. In Osteoarthritis, this process is disrupted leading to degenerative changes and abnormal repair response.

Despite increasing awareness of the negative effects of obesity on health and OA in particular, the prevalence of individuals who are overweight or obese is increasing. Data from the National Health and Nutrition Examination Survey (NHANES) collected between 1999 and 2000 show that 64.5% of the US population is overweight, including 30.5% classified as obese. Carrying extra weight biomechanically places increased stress and force on the weight-bearing joints. Other common risk factors include joint injury, mechanical stress, history of immobilization and trauma.

Arthritis treatment first begins with education. Treatment for osteoarthritis can help relieve pain and stiffness; however, the condition can progress. Physicians will tend to focus to help those afflicted with OA by helping patients manage their pain. There are several ways to do this. The first commonly used approach is pharmacologic intervention. Traditional non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to be effective for OA pain, and are perceived as second-line drugs for the treatment of mild to moderate OA. Physical therapy is very effective in helping those suffering with OA. Where the focus is on helping the patient by improving their muscle flexibility, joint mobility and strengthening the weaker hip musculature. Resulting in improved mobility, function, decrease pain and improved quality of life.Strengthening the core begins with simple exercises such as bridging with the ball (Figure 1), targeting glute maximus, hamstrings, and the lower back musculature. This can be progressed to having the client hold longer or to perform a single leg bridge. Functional strengthening exercises such as reverse lunges holding a medicine ball that can be progress to either holding overhead or adding trunk rotation will do two things. Figures 2 and 3). The use of aqua therapy can also be effective which eliminates gravity resulting in a client’s ability to strengthen their lower body in a relaxed environment.

Arthritis continues to affect many individuals for various reasons. One thing is certain, knowledge, prevention and early screening is fundamental. Understanding the pathological process and medical approach is the first step in helping your clients with OA. Refreshing yourself on anatomy, biomechanics and understanding proper exercise prescription is fundamental. Any exercise program should be individualized resulting in improved function, strength gains, weight loss and a client that will be truly appreciative of your comprehensive approach.
