Osteoarthritis is a degenerative disease of the joint. This means the tissues in the joint deteriorate or break down over time. Mayo Clinic reports osteoarthritis is the most common form of arthritis, usually occurring more often in older adults. It is most commonly caused by gradual joint deterioration, often due to aging.
As osteoarthritis progresses, the joints may become misshapen. Small bone growths, such as bone spurs, may also grow on the edges of the joint, causing discomfort.
Osteoarthritis can affect people to varying degrees. Symptoms generally start mild and progress. Common symptoms include the following:
- Joint pain
- Stiffness
- Reduced range of motion
- Joint instability
- Joint swelling
Osteoarthritis can adversely impact exercise and physical activity. Due to joint pain and stiffness, individuals with osteoarthritis may become less physically active.
Less physical activity can lead to increased stiffness, decreased range of motion, and overall deconditioning. Being less active may also cause muscle weakness and, subsequently, additional stress on the joint. This can make starting a fitness or exercise program challenging.
Forms of Osteoarthritis
Osteoarthritis (OA) can affect different joints of the body, and types may include the following:
- Knee OA: This involves the cartilage in the knee joint.
- Hip OA: This consists of a breakdown of the smooth cartilage that lines the hip joint.
- Hand OA: Different areas of the hand may be involved, such as the base of the thumb, the joints closest to the fingertips, and the middle joints of the finger.
- Back OA: This form of OA typically involves the facet joints between the vertebrae. It can develop anywhere in the spine, with the lower back being the most common sight.
Importance of Physical Activity for Managing OA Symptoms
Physical exercise is essential for managing osteoarthritis symptoms. Regular exercise can help strengthen the muscles that support the joint, reducing discomfort. Exercise is also helpful for promoting a healthy weight. It also helps decrease stiffness and improve range of motion and balance.
Some people may believe that osteoarthritis individuals should avoid exercise altogether. This cannot be further from the truth. Avoiding exercise entirely will lead to decreased muscle mass, stiffness, deconditioning, and a potential increase in bone loss.
The key is finding exercise that doesn't put too much stress on the joints. According to the National Institute of Arthritis, Musculoskeletal and Skin Diseases, engaging in low-impact activities that give you a moderate level of activity without putting additional stress on the joints is helpful.
