Osteoarthritis is the irritation and inflammation of synovial joints, especially those that are weight-bearing. It is primarily caused by the wear and tear of the joint structures and is the most common form of arthritis. Symptoms include inflammation, pain and stiffness of joints.
Any arthritis in an acute stage contraindicates massage as it may increase inflammation. Chronic osteoarthritis generally responds well to massage, easing pain and helping to retain range of motion.
