Chronic pain is due to weakened and damaged tissues. Ligaments once damaged are not able to regain their original function, strength or length, resulting in unstable,wobbly joints that cause pain. Prolo therapy is short for proliferative therapy. It is used to strengthen and tighten joints, tendons and ligaments as an alternative and possibly better treatment than surgery, chiropractic manipulation, corticosteroids, and the non-steroidal, anti-inflammatory agents used today with or without their side effects. Solutions are injected into ligaments, tendons, joint capsules and joints themselves which causes a proliferation of connective tissue to strengthen the injected tissue. The chronic ligament and tendon laxity causing the chronic pain in man and beast is corrected and pain dissipates.
