Rotator cuff tear to ten weeks. The effect of active or passive motion during any of the phases is unclear, due to conflicting information and a shortage of clinical evidence. Gentle physical therapy guided motion is instituted at this phase, only to prevent stiffness of the shoulder; the rotator cuff remains fragile. At three months after surgery, physical therapy intervention changes substantially to focus on scapular mobilization and stretching of the glenohumeral joint. Once full passive motion is regained (at usually about four to four and a half months after surgery) strengthening exercises are the focus. The strengthening focuses on the rotator cuff
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
