Yes, they do seem to help people. I'm going to use some fancy words to attempt to explain why we think they work. Wearing a brace is technically called lateral counter-force bracing. Therapists believe that lateral counter-force bracing reduces the magnitude of muscle contraction. Reducing the amount of load ( force ) placed on the tendons reduces the amount of micro-trauma in the region of the muscular attachment.
A lateral counter force brace is basically an inelastic cuff that is worn around on the forearm near the elbow joint. For lateral epicondylitis the brace is placed against the forearm flexors. The forearm flexors are the muscles that pull the top of the hand back towards the elbow.
