Other, more rare forms of arthritis are juvenile rheumatoid arthritis -- affecting kids -- and infectious arthritis.

All forms of arthritis are caused by an injury to a bone.

The correct answer is: FALSE

Osteoarthritis may be caused by wear and tear or broken bones but the other types of arthritis have different causes. Experts say rheumatoid arthritis is caused by an autoimmune disorder. Infectious arthritis is caused by a bacteria or virus and often comes on after another disease, such as staph infection or Lyme disease. Though the causes of arthritis vary, the result is the same: joint inflammation.

A diet high in fiber has been shown to be effective in the treatment of osteoarthritis.

The correct answer is: FALSE

While no specific diet has been shown to be effective in treating osteoarthritis, obesity does contribute to osteoarthritis of weight-bearing joints. Therefore, if you carry extra weight, you should work with your doctor to develop a sensible eating and exercise plan to lose the weight and avoid the added stress on your joints.

The correct answer is: FALSE

To manage the chronic pain that may accompany arthritis, many doctors recommend therapy that helps a person relax and do their daily activities at a realistic pace. Various techniques may be helpful, such as visualization, distraction, and creative problem solving.
