Mention of older people will always be in the mind wearing maintenance in the park walking picture, in fact, walk into a variety of fitness, ball clubs, the elderly are also increasingly important main force, vitality is no less than young people. With a large number of sports activities, the elderly face more and more sports injuries, often appear various parts or joint pain and soreness, usually many people will choose painkillers and rest or acupuncture and massage to relieve pain, part of the elderly gradually recovered after conditioning and recuperation, there are some elderly friends recovered quickly, but again sports pain will still exist, there are some elderly after a variety of There are also some elderly people who do not see any improvement even after various means. Today we will start with the shoulder to understand one of the causes of pain after sports injuries – rotator cuff tears. Shoulder pain has a significant impact on muscle function. Under dynamic conditions, pain in motion reduces active force, which may be a protective reflex of the body, and in some older adults the contraction of the antagonist muscles does not increase. Likewise, movement patterns are altered to avoid pain. These phenomena occur in any situation where pain is present, whether after trauma or under load, and can lead to coordination deficits of their own, in which case the faulty movement pattern can also persist permanently. Since the shoulder joint has more forms of movement than any other joint in the body, there are few bony restrictions that impede these movements, and its stability and motion are controlled primarily by the shoulder muscles and soft tissues. Therefore, trauma and overuse injuries to the shoulder can massively disrupt the different internal and surrounding structures of the shoulder. Rotator cuff tears also arise, and the trauma usually caused can be divided into direct and indirect injuries. I. Direct trauma Direct trauma is a shoulder injury from a punch or a fall, usually on the side or in front. The most common occurrence of this condition in most elderly people is a fall while riding a bicycle. Older people who have fractures may be able to avoid increased pain through timely treatment, but many of them go to the hospital and find that the bones are fine and consider it a simple soft tissue injury and do not go further to check and Treatment. Indirect trauma Indirect trauma is caused by the transmission of external forces in the arm. The most fragile tissues are most likely to be injured in trauma. Children have soft bones and epiphyseal plates and have a higher incidence of pulling the connection between bone and ligament or joint capsule than tearing the soft tissues and also detaching the epiphysis of the greater tuberosity of the humerus or humeral neck compared to adults with strong bones. In young and middle-aged adults, it is usually the soft tissues that are most vulnerable. Whereas in older adults over the age of 60, the natural decrease in the mineral content of the bone increases the incidence of fractures and ligament pulls, tendons – especially those of the rotator cuff and the long head of the biceps – also become increasingly fragile with age to the point where Tearing can occur after smaller traumatic injuries or even natural tears can occur, such as when playing tennis or badminton. Repeated strong external forces applied to body structures during exercise can cause overuse injuries, which in most older people are caused by increased exercise intensity, improper use of new techniques or equipment, etc. Applying more load to soft tissue structures than the tissues can handle can lead to inflammation and pain, an acute condition that can be easily reversed if the load is adjusted according to capacity. The following types of exercise may be what you are doing right now. Swimming is a comprehensive exercise that many older adults love, and because it can cause a lot of repetitive gyration of the acromioclavicular joint during exercise, any such mechanism can cause inflammation and progressive degenerative disease of the acromioclavicular joint. Playing gyro is a favorite of many older men, and because the best positions for gyro are obtained with the shoulder lifted (i.e.: a fully abducted and extremely externally rotated position), it can cause a very specific injury. This action will naturally stop when a collision occurs between the lower surface of the supraspinatus and infraspinatus tendons and the upper part of the articular labrum. Repeated forceful collisions cause abrasion of both structures and elongation of the lower part of the glenohumeral ligament (leading to glenohumeral instability and secondary impingement). Repeated use of the rotator cuff during power movements during sports does not significantly cause wear of the rotator cuff or the long head of the biceps tendon; such changes are more likely to be caused by repeated micro-injuries and small partial tears.
