Rotator cuff tear correlation with injuries occurred during those movements. The evidence shows that putting the arm in a neutral position relieves tension on all ligaments and tendons. One article observed the influence of stretching techniques on preventative methods of shoulder injuries. Increased velocity of exercise increases injury, but beginning a fast-movement exercise with a slow stretch may cause muscle/tendon attachment to become more resistant to tearing. When exercising, exercising the shoulder as a whole and not one or two muscle groups is also found to be imperative. When the shoulder muscle is exercised in all directions, such as external rotation, flexion, and
Synovial sheath Synovial sheath A synovial sheath is one of the two membranes of a tendon sheath which covers a tendon. The other membrane is the outer fibrous tendon sheath. The tendon invaginates the synovial sheath from one side so that the tendon is suspended from the membrane by the mesotendon, through which the blood vessels reach the tendon, in places where the range of movement is extensive. The mesotendon disappears or remains in the form of narrow tendinous bands as threads known as vincula tendina. The synovial sheath is found where the tendon passes under ligaments and through osseofibrous tunnels; their
