According to the CDC, during 2019-2021, 1 in 5 adults in the United States experienced doctor-diagnosed arthritis. Since then, the number has consistently increased! The latest statistics from Health.Gov estimate the number of reported arthritis diagnoses is now 1 in 4, which is not only a leading cause of disability, but also a significant driver of economic costs.

Arthritis comes in many forms and has many manifestations, affecting almost every joint in the body. We generally speak in terms of the two most-known if not popular forms of arthritis: rheumatoid (RA) and osteo-arthritis (OA.) The essential difference is in the root cause. RA is an auto-immune disease whereby the body, for unknown reasons, attacks itself, particularly in the joints. OA, on the other hand, is often considered the downstream effect of wear and tear, over-use, prior injury, or, as we’re seeing more of as society gets more sedentary, from lack of use. In OA, typically, some insult to the joint disrupts the natural repair processes and further deterioration occurs subsequently.

Due to their differing causes, there are obviously differing treatments; but the basics of medical management are essentially the same. I am not qualified to address the specifics of the treatments available but, in lay terms, treatment usually entails some version of anti-inflammation and pain-reduction drugs, precautionary movement or positional guidance (don’t do’s, for example), physical therapy to manage pain and inflammation, and therapeutic exercises to support the structures affected as the disease itself causes not just inflammation and pain but damage to the structures that support the joints. Typically we identify arthritis as something that damages cartilage and, in truth, that is often what the standard ‘films’ – X-ray, possibly MRI (magnetic resonance imaging) – show. We now know that the synovial sacs around the joint are also affected and that these and other chemical disturbances affect the muscles and tendons that move and support the joint. In almost all cases of arthritis, pain, inflammation, reduced strength and range of motion (ROM) ensue, diminishing quality of life in many ways and, because some of the drugs used to treat it, potentially reducing quantity of life. (Gastrointestinal bleeding from non-steroidal anti-inflammatories (NSAIDs) or bone loss (osteoporosis) from corticosteroids can lead to fatal outcomes (such as spontaneous fractures leading to falls from osteoporosis) if not treated with other medications.)

When someone is potentially afflicted or actually diagnosed with a form of arthritis, the medical community goes into hyper-drive, encouraging changing one’s habits, be they the types of activities one engages in recreational, competitively, or professionally; or the types of non-activities one currently does, in particular, being inactive.

In some cases, dietary advice is offered as we are learning more about foods that are pro-inflammatory and others that have anti-inflammatory benefits. In the former category, we are learning that excessive sugar or simple carbohydrates, including processed wheat products, may exacerbate inflammation while others, such as salmon, dark, green veggies, and certain oils (e.g., olive oil) are capable of reducing the inflammatory elements circulating throughout our bodies and our joints. Furthermore, in more extreme cases, when arthritis becomes very painful and debilitating, over-the-counter and/or prescription-fitted braces may be offered to defer some of the more end-line procedures such as surgery to fuse the joint or replace it with a prosthetic device.

The most common non-pharmaceutical and non-surgical treatment for arthritis of any sort: exercise.

Note that there are several legitimate ways to integrate exercise through resistance training programs that have proven quite effective in arthritis management. Yoga, Pilates (floor or machine based), Tai Chi, Qigong and water-based, or aqua, exercise are all beneficial to many aspects of the overall arthritis program of strength, ROM, proprioception and ultimately function. Since many of these are quite technical and are often done in class formats, one should ask the instructor(s) as to their experience working with arthritis clients.

As with any form of exercise, by whatever professional instruction, you should be totally aware of your pain levels as going “through” the pain is not recommended; thus, you must assert control over the exercise sessions. There will be some exercises, however, that are not destructive and may be somewhat painful but must be done in order to maintain reasonable levels of function and independence. So long as the pain subsides within a couple of hours – preferably as soon as you stop – and there is no exacerbation of inflammation the next day, you can assume that the exercise was just enough. If symptoms flare up over the next 24 hours, however, assume you did more than you should have and alert your trainer or instructor so that he/she can avoid doing the aggravating exercise(s) as much or as hard next time. For these reasons, along with all the other recommendations so far as exercise interventions are concerned, it is best to seek the counsel and assistance of a fitness professional with a background in medical fitness. This could be someone with a more advanced academic degree, someone with a license to practice rehabilitation exercise (physical therapist, athletic trainer, etc.), or someone who’s taken several educational programs to have a greater understanding of the variety of disorders and diseases that may benefit from exercise interventions.

Dr. Irv Rubenstein graduated Vanderbilt-Peabody in 1988 with a PhD in exercise science, having already co-founded STEPS Fitness, Inc. two years earlier — Tennessee’s first personal fitness training center. One of his goals was to foster the evolution of the then-fledgling field of personal training into a viable and mature profession, and has done so over the past 3 decades, teaching trainers across through country. As a writer and speaker, Dr. Irv has earned a national reputation as one who can answer the hard questions about exercise and fitness – not just the “how” but the “why”. 

Osteoarthritis (OA), the most common form of arthritis, affects some 27 million adults per year and is on the rise. The Centers for Disease Control and Prevention (CDC) estimates that in 2005, self-reported arthritis or other chronic joint symptoms affected approximately 21.4 million Americans aged 65 years and older. This estimate is expected to reach 41.1 million by 2030. Osteoarthritis makes simple movements and activities of daily life painful and difficult to perform.

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.

Pathology

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. 2 

Contributing Factors

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 places 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.

Medical Management

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.

Training Recommendations

Because arthritis is a “process,” the most effective training is education and prevention. From a cardiovascular perspective, a cardiovascular program should be tailored to the client. A recumbent or stationary bike is a great starting point to reduce the load to the hips and knee which can be progressed to the elliptical machine. Stretch the tight (postural) hip flexors and quadriceps seen in figure one will reduce the load to the knee joint. Yoga can also be an effective intervention which will improve flexibility, balance, strength and body awareness. Strength training should focus on targeting the weaker phasic muscles; glute maximus, glute medius/minimus as seen in figure two. These muscles are necessary for everyday movements such as arising from a chair, climbing stairs, and negotiating uneven surfaces.

Strengthening the core begins with simple exercises such as bridging with the ball (figure three), 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. four and figure five). 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.

Summary

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.
