New treatment for tennis elbow
Steroid injections are no longer routinely recommended for lateral epicondylitis (tennis elbow). Instead, physical therapists offer an alternative treatment in the form of something called iontophoresis.
In this article, the use of steroid injection is compared with iontophoresis delivered in two different ways. Iontophoresis uses a small electric current to drive steroid medication through the skin. It is a noninvasive method of reducing the pain of tennis elbow.
