An elbow brace works the same way as other upper extremity orthopedic supports. However, this arm support reduces pressure on the injured tendon in your elbow by increasing pressure on your forearm muscles. Since elbow supports are very effective in easing elbow pain, they are popular with golfers, tennis players, baseball players, and other athletes who tend to overuse their elbow joints. Elbow braces also help workers continue or return to work despite elbow injuries or conditions.
