Joint stiffness is a common characteristic of arthritis. It is defined as discomfort after a period of inactivity, decreased range of motion or a loss of range of motion in a joint. With osteoarthritis, joint stiffness after waking may last up to 30 minutes.
With inflammatory types of arthritis such as rheumatoid arthritis or systemic lupus erythematosus, the stiffness typically lasts more than 45 minutes. Joint pain may also be caused by bursitis. The bursae are fluid-filled sacs that cushion and pad bony prominences, allowing muscles and tendons to move freely over the bone.
Causes of Joint Stiffness
Joint stiffness is caused by inflammation in the synovium, the lining of the joint and joint pain can be caused by many types of injuries or conditions. No matter what causes it, joint pain and stiffness can be very bothersome.
Rheumatoid arthritis is an autoimmune disorder that causes stiffness and pain in the joints. Osteoarthritis involves growth of bone spurs and degeneration of cartilage at a joint. It is very common in adults older than 45 and can cause joint pain. Other medical conditions can also cause joint stiffness, including bone diseases, cancer, joint trauma, or overuse of the joint. |
