Arthritis
What Is Arthritis?
Arthritis is a general term that refers to many rheumatic diseases that can cause pain, stiffness, and swelling in joints and other connective tissues. These diseases can affect supporting structures such as muscles, tendons, and ligaments and may also affect other parts of the body. Some common types of arthritis are osteoarthritis, rheumatoid arthritis,systemic lupus erythematosus,gout,juvenile rheumatoid arthritis,ankylosing spondylitis, and psoriatic arthritis.Osteoarthritis is the most common.
Arthritis causes pain and loss of movement. It can affect joints in any part of the body. Arthritis is usually chronic, meaning it can occur over a long period of time. The more serious forms can cause swelling, warmth, redness, and pain. The three most common kinds of arthritis in older people are osteoarthritis, rheumatoid arthritis, and gout.
Common Forms of Arthritis
Osteoarthritis (OA), at one time called degenerative joint disease, is the most common type of arthritis in older people. Symptoms can range from stiffness and mild pain that comes and goes to severe joint pain and even disability.
OA usually affects the hands and the large weight-bearing joints of the body: the knees and hips. Early in the disease, pain occurs after activity and rest brings relief; later on, pain occurs with very little movement, even during rest.
Scientists think that several factors may cause OA in different joints. OA in the hands or hips may run in families. OA in the knees is linked with being overweight. Injuries or overuse may cause OA in joints such as knees, hips, or hands.
Rheumatoid arthritis (RA) can be one of the more disabling forms of arthritis. Signs of RA often include morning stiffness, swelling in three or more joints, swelling of the same joints on both sides of the body (both hands, for example), and bumps (or nodules) under the skin most commonly found near the elbow. RA can occur at any age and affects women about three times more often than men.
Scientists don’t know what causes RA but think it has something to do with a breakdown in the immune system, the body’s defense against disease. It is also likely that people who get RA have certain inherited traits (genes) that cause a disturbance in the immune system.
Gout occurs most often in older men. It affects the toes, ankles, elbows, wrists, and hands. An acute attack of gout is very painful. Swelling may cause the skin to pull tightly around the joint and make the area red or purple and very tender. Medicines can stop gout attacks, as well as prevent further attacks and damage to the joints.
Treatments
Treatments for arthritis work to reduce pain and swelling, keep joints moving safely, and avoid further damage to joints. Treatments include medicines, special exercise, use of heat or cold, weight control, and surgery.
Medicines help relieve pain and reduce swelling. Acetaminophen or ACT should be the first drug used to control pain in patients with osteoarthritis (OA). Patients with OA who don’t respond to ACT and patients with RA and gout are most commonly treated with nonsteroidal anti-inflammatory drugs such as ibuprofen. People taking medicine for any form of arthritis should limit the amount of alcohol they drink.
Exercise, such as a daily walk or swim, helps keep joints moving, reduces pain, and strengthens muscles around the joints. Rest is also important for the joints affected by arthritis. Physical therapists can develop personal programs that balance exercise and rest.
Many people find that soaking in a warm bath, swimming in a heated pool, or applying heat or cold to the area around the joint helps reduce pain. Controlling or losing weight can reduce the stress on joints and can help avoid further damage.
When damage to the joints becomes disabling or when other treatments fail to reduce pain, your doctor may suggest surgery. Surgeons can repair or replace damaged joints with artificial ones. The most common operations are hip and knee replacements.
Should People With Arthritis Exercise?
Yes. Studies have shown that exercise helps people with arthritis in many ways. Exercise reduces joint pain and stiffness and increases flexibility, muscle strength, and endurance. It also helps with weight reduction and contributes to an improved sense of well-being.
How Does Exercise Fit Into a Treatment Plan for People With Arthritis?
Exercise is one part of a comprehensive arthritis treatment plan. Treatment plans also may include rest and relaxation, proper diet, medication, and instruction about proper use of joints and ways to conserve energy (that is, not waste motion) as well as the use of pain relief methods.
What Types of Exercise Are Most Suitable for Someone With Arthritis?
Three types of exercise are best for people with arthritis:
Range-of-motion exercises help maintain normal joint movement and relieve stiffness. This type of exercise helps maintain or increase flexibility.
Strengthening exercises help keep or increase muscle strength. Strong muscles help support and protect joints affected by arthritis.
Aerobic or endurance exercises improve cardiovascular fitness, help control weight, and improve overall function. Weight control can be important to people who have arthritis because extra weight puts extra pressure on many joints. Some studies show that aerobic exercise can reduce inflammation in some joints.
How Does a Person With Arthritis Start an Exercise Program?
People with arthritis should discuss exercise options with their doctors. Most doctors recommend exercise for their patients. Many people with arthritis begin with easy, range-of-motion exercises and low-impact aerobics. People with arthritis can participate in a variety of, but not all, sports and exercise programs. The doctor will know which, if any, sports are off-limits.
The doctor may have suggestions about how to get started or may refer the patient to a physical therapist. It is best to find a physical therapist who has experience working with people who have arthritis. The therapist will design an appropriate home exercise program and teach clients about pain-relief methods, proper body mechanics (placement of the body for a given task, such as lifting a heavy box), joint protection, and conserving energy.
