Rotator cuff tear recovering from large rotator cuff tears, are prone to developing new tears. Rehabbing too soon or too strenuously might increase the risk of retear or failure to heal. However, no research has proven a link between early therapy and the incidence of re-tears. In some studies, patients who received earlier and more aggressive therapy reported reduced shoulder pain, less stiffness and better range of motion. Other research has shown that accelerated rehab results in better shoulder function. Ross et al. note that, despite the findings, "no definitive consensus exists supporting a clinical difference" between the two methods of rehab. There
Posterior compartment of the forearm De Quervain's syndrome is a medical condition when the synovial sheath surrounding tendons in the first extensor tendon compartment becomes inflamed, so called tenosynovitis. The tendons of the abductor pollicis longus and the extensor pollicis brevis run narrower due to the thickening of the synovial sheath, which causes pain when extending and moving the thumb outward. Carpal tunnel syndrome is a condition when the median nerve is compressed as it passes through the carpal tunnel, which causes pain, numbness and tingling. The presence of an additional tendon may result in a condition called fourth compartment syndrome. Supernumerary tendons are common
