The deltoid and rotator cuff Erase My Back Pain muscles work synergistically to maintain a balance of forces around the shoulder joint in every direction. The deltoid and infraspinatus/teres minor maintain a balance in the vertical plane, while the subscapularis and infraspinatus balance each other in the horizontal plane. With lifting of the arm, the deltoid generates an upward force that is resisted by the downward force produced by the rotator cuff muscles, preventing a loss of reduction of the humeral head on the glenoid. A tear in these muscles can disrupt this balance of forces and compromise normal shoulder joint motion. In fact, a high riding humeral head that shifts superiorly off the glenoid with raising of the arm can be seen in the setting of a massive tear.A torn rotator cuff is a disruption in the integrity of the tendon at the insertion into the humeral head. Tendons connect the rotator cuff muscle belly to bone. Most commonly, tears involve the supraspinatus tendon but can involve any combination or all four of the rotator cuff tendons. The mechanism of injury can be highly variable. A torn rotator cuff can result from trauma such as a fall on the shoulder or after a shoulder dislocation. More commonly, however, athletes suffer this injury from repetitive wear and tear activities that strain and chronically fail the tendon. Such tears are particularly prevalent in overhead athletes and are often seen in tennis players, baseball pitches, javelin throwers, swimmers, and football quarterbacks. Sometimes, a narrow space for passage of tendon underneath the acromion can result in direct mechanical abrasion of the tendon. This has been termed outlet impingement and is commonly referred to as impingement syndrome. A prominent acromial spur and thickened bursal tissue in the subacromial space can abrade the tendon running underneath.Damage and ultimately tearing of the rotator cuff tendons has been attributed to either static or dynamic causes. Static changes refer to impingement and mechanical abrasion of the tendons from narrowing of the subacromial space, most commonly due to roughness or "spurring" on the underside of the acromion or thickening of the coracoacromial ligament. On the other hand, a torn rotator cuff can result from abnormal dynamic motion of the humeral head and cuff relative to scapula, leading to abnormal strain on the tendon and tearing on either the joint or bursal side. For example, muscle weakness can allow the humeral head to rise higher towards the acromion and is considered to be one of the most common dynamic causes of a torn rotator cuff in athletes. https://optimusforexreview.com/erase-my-back-pain-review/
