Detailed Study Description

Lateral epicondylalgia or tennis elbow is a common painful elbow disorder with a prevalence of 1% to 3% in the general population and has a higher rate up to 14.5% in strenuous jobs. Botulinum toxin type A injection was an emerging option in treating lateral epicondylalgia. In this study, the patients were randomly assigned into three groups:

  1. Botox-Epic group received 20 units of Botox injection into lateral epicondyle;
  2. Botox-Tend group had 20 units of Botox injected into tender point of muscles;
  3. Steroid group had 40mg of triamcinolone injected into lateral epicondyle.
