Shockwave therapy for Achilles tendonitis is effective. The therapeutic effect of shock wave has the effect of loosening adhesion, promoting bone healing, analgesia and accelerating metabolism. 1. Through cavitation effect, improve local blood circulation, stimulate tissue repair, loosen soft tissue adhesion. 2. Through osteogenic effect, it induces the migration of osteoblasts and the formation of new bone tissue. 3. Through analgesic effect, reduce nerve sensitivity and block nerve conduction function, so as to relieve pain. 4. Through metabolic activation effect, it changes the permeability and polarity of cell membrane and accelerates the removal and absorption of metabolic decomposition products. Achilles tendonitis is one of the indications for shockwave therapy. Shockwave therapy can change the environment around the Achilles tendon, relieve pain as well as edema, etc., and promote the recovery of Achilles tendonitis. In addition, it can also be combined with other measures such as acupuncture, drug therapy, closed treatment and so on. It has better therapeutic effect.
