• While there are many forms of arthritis that can be treated by PST, one of the most common forms of arthritis that is responsive to PST is osteoarthritis (OA) or degenerative joint disease. OA is a condition that develops gradually, over several years. For some people, the changes are subtle and occur over such a long period of time that they are hardly noticeable. Others, however, may experience gradual worsening, including pain and restricted movement, particularly in large joints such as the hip or knee.

• In a healthy joint, the layer or cartilage that covers the bone end is very strong, smooth and flexible. It absorbs the stresses put on a joint and protects the bones from damage. In osteoarthritis, this becomes brittle, thin and pitted and over time, can wear out completely. When the cartilage deteriorates, the bone underneath thickens and broadens out. As the cartilage becomes thinner, the bones of the join rub together, causing pain, inflammation and the gradual build-up of bony outgrowths (osteophytes), which make it look knobbly. Also, the joint capsule becomes thicker and the amount of synovial (lubricating) fluid can increase, often causing the joint to swell. This can cause it to become stiff and painful.

• PST produces magnetic fields that stimulate chondrocytes (cartilage-producing cells) and fibroblasts (connective tissue producing cells) into regenerating their respective tissues. Tissue cultures of chondrocytes stimulated by PST have shown a markedly higher production of cartilage. Because of this, PST can reverse the changes in joint structure caused by arthritis and help to stabilize the joint’s synovial fluid. This will result in a further improvement in overall joint function.
