Correlations between the duration of pain and the success of shock wave therapy

Patients who have had successful treatment for either chronic heel pain (plantar fasciitis) or humeral epicondylitis subsequently were evaluated for a comparable problem in the contralateral heel or elbow. Patients who had experienced symptoms in the contralateral heel or elbow for a shorter period were less likely to have a positive result from shock wave therapy than those patients who had received treatments for more chronic symptoms.
