| Animal Study*
Vascularization | Shock Wave Therapy Induces Neovascularization at the Tendon-Bone Junction: A Study in Rabbits | Journal of Orthopaedic Research, 21 (2003) pp. 984-989 | C. Wang, MD | Article finds that “the mechanism of shock wave therapy involved the early release of angiogenic growth factors (eNOS and VEGF) and subsequent induction of neovascularization and tissue proliferation. The neovascularizatoin may play a role in pain relief of tendonitis and the repair of chronically inflamed tendon tissues at the tendon-bone junction.” |
| Lateral Epicondylitis | Shock Wave Therapy for Patients with Lateral Epicondylitis of the Elbow: A One- to Two- Year Follow-up Study | The American Journal of Sports Medicine, Vol. 30, No. 3, 2002 | C.
