Why do doctors advise their patients to wear an elbow brace?
Depending on whether the brace is used to immobilize the elbow or to support it while the arm is being actively use the theory is that a brace will limit irritation and further damage to the tendon structure attaching to the Lateral Epicondilytis. If one chooses to think about lateral elbow tendonitis like this, then wearing a brace or sling or splint should keep things from getting worse and make things better. Unfortunately, this rarely turns out to be the case.
