The purpose of this project is to compare different treatment options for lateral epicondylitis. Lateral epicondylitis is a pain condition involving extensor muscles fo the forearm originating from the lateral epicondyle. Controversy exists regarding the method of delivering pain relief so that conditioning and strengthening can be initiated and progress appropriately. Our hypothesis is that the steady even delivery via iontophoresis (compared to injection will provide better pain control and allow physical therapy to progress more effectively.
