OA causes some mild aches and pains but never really incapacitates people. Unfortunately, in many individuals it is more than a minor problem, and can lead to significant pain, limitation, and overall disability, particularly when it involves significant joints such as the hips, knees, or spine. There are many coping strategies to consider for those with OA. What is Arthritis? The word arthritis is derived from two Greek words. The first, athron, means joint. The second, itis, means inflammation, Literally translated then, arthritis means inflammation of a joint. (Gordon, 1993:7) Inflammation of a joint is vital in the renewing process that occurs in response to injury of living tissue. It's a positive healing process provided it ends in relatively short time and does not linger indefinitely and become chronic. It's the chronic nature of arthritic inflammation that's negative and sets in motion the chain reaction leading to arthritic symptoms and signs (such as joint pain, tenderness, warmth, swelling, and redness) and complications. (Gordon, 1993:7) OA and rheumatoid arthritis are the two most common types. ...read more.

(Phillips, 1989:8) How does Osteoarthritis affect Joints? OA affects the synovial membrane that covers the bony ends of all joints. At first it may manifest in one bone end or joint only. (Figure 1) However, it may invade other joints as the person ages. As the disease progresses, the membrane begins to wear away and the end of the affected bone is gradually exposed. Eventually the space between the bone end narrows to such an extent that often the raw bone ends rub together, causing excruciating pain on movement. (www.arthritisvic.org.au) Normally, cartilage acts as a shock absorber, providing a smooth surface between the bones. But with OA, the smooth surface becomes rough and pitted. In advanced stages, it may wear away completely. Without their normal gliding surfaces, the bones grind against one another, causing inflammation, pain and restricted movement. Bone spurs may form. (www.arthritisvic.org.au) In OA of the knee, the shape of the bone and appearance of the leg may change over the years. Many people become bow-legged or knock-kneed. And in OA of the hip, the affected leg may appear shorter. What Occurs inside the Joint? OA is defined by the changes that are seen on an X-ray of the joint with symptoms. Compared to a normal joint, the X-ray more or less shows, depending on the joint and on how long the problem has been going on: (see figure 2) ...read more.

Conclusion

A balanced routine of rest and exercise is best. What about surgery? (Taken From www.fla-ortho.com) > Arthroscopy - Arthroscopic procedures are not generally helpful for arthritis. In some cases, a "flap" of torn knee cartilage can aggravate arthritis and cause additional pain. The cartilage flap can be removed by Arthroscopy. > Partial Knee Resurfacing - An alternative to total knee replacement for people who have arthritis on either the inside or outside compartment of the knee. Partial Knee Resurfacing restores only the compartment that is damaged by arthritis. It can be an excellent option for people who have "bone on bone" arthritis. > Knee or Hip Replacement - Knee replacement or hip replacement is a very positive solution to the pain and disability of advanced OA. The rough, worn surfaces of the joint are relined with smooth-surfaced metal and plastic components. Future of Osteoarthritis Tremendous progress has been made in treatment for OA. Earlier diagnosis has led to earlier, more effective treatment, resulting in a better prognosis. Ongoing research continues to investigate the ways that joints function, as well as techniques that may decrease damage to bones and tissues and improve bone growth and repair. Finally, more attention is being given to find ways to further improve quality of life for the person with OA. It is hoped that scientists may soon discover other types of treatment that may entirely eliminate OA as a medical problem. Until then, it is necessary to develop adequate coping strategies.

    Facial expressions were a key indication that the performer wasn't in control and wasn't processing the movement of the game. Their eyes were noticeably unfocussed and this affected the way in which they perceived situations. If the player lacks concentration then their athletic abilities will not be effectively or efficiently applied to the task.
