Shockwave is a high-energy pressure wave generated by the sudden release of energy, which has the characteristics of instantaneous pressure increase and high-speed conduction. After the shock wave acts on the body, it produces biological effects through force-chemical signal transduction, promotes the release of cytokines, causes microvascular neovascularization and tissue regeneration and repair response. Indications for shock wave therapy 1. Bone tissue diseases: delayed fracture healing, fracture disjunction, adult ischemic necrosis of the femoral head (early and middle stage). 2, soft tissue chronic injury diseases: subacromial bursitis, biceps long head tendonitis, calcific supraspinatus tendonitis, humeral medial epicondylitis, tennis elbow, bouncing hip, jumping knee, heel pain, patellar tendonitis, supraspinatus tendon injury, etc.
