Relieves pain, discomfort associated with tennis elbow and swimmers arm. The ElbowGard works by Appling pressure on the extensor and flexor muscles, and absorbs vibrations to reduce the pain while holding soft tissue in place and still allowing for proper circulation. The Elbowgard is a Lateral counter-force brace. The Eblowgard reduces the magnitude of muscle contraction which in turn reduces the degree of muscle tension in the region of muscular attachment. The Elbowgard counter-force brace is an inelastic cuff that is worn around the proximal (near) forearm (against the forearm extensors for lateral epicondylitis and around the forearm flexors for medial epicondylitis). The Elbowgard brace constrains full muscle expansion when the muscle contracts, diminishes muscle activity, and therefore the force generated by the muscle. The Elbowgard Counter-force bracing is a supplement to, not a replacement for your rehabilitation program. The ElbowGard is Lightweight and migration resistant. It is easy to adjust with gradient pressure for constant support. One Size Fits All. Tendonitis, Medial and Lateral Epicondylitis, Tennis Elbow, Golfer's Elbow Symptoms: Pain in the outside (lateral) or inside (medial) aspect of the elbow, exacerbated with gripping or squeezing. Usually pain free at rest. Tennis elbow usually develops from repeated, forceful forearm or wrist movements involving grasping and elbow twisting. Overuse of the forearm muscles using a repeated twisting motion is the most common cause of tennis elbow. These movements are common to racquet and throwing sports, swimming, and golf, various occupations such as carpentry or plumbing, and many daily activities such as yard work and lifting objects. Tennis elbow injuries can result from: Overuse. Repeated movements that involve twisting of the elbow cause small tears in the tendon, weakening it. Overuse depends on how hard or how long you do something.
