Tennis elbow, or lateral epicondylitis, is an inflammation on the outside of the elbow. It often comes from an overuse injury. This video shows you my favorite stretches & exercises for tennis elbow.
To start off, soft tissue mobilization (STM) can be very beneficial for tennis elbow. This is not rubbing the area, but you are actually mobilizing or moving the tissue around to help break up adhesions and scar tissue.
Next stretching the inside and outside of the elbow helps. Wrist extensor stretches and wrist flexor stretches will help loosen up the area. Stretches in general can be done with a 30 second hold, 3 times.
Then working on AROM and strengthening for wrist extension, radial/ulnar deviation, and pronation/supination will help decrease the inflammation and improve motion.
Finally a towel twist is a great way to strengthen the muscles as well.
