Shoulder pain and movement difficulties are mostly caused by rotator cuff injury, rotator cuff impingement sign and shoulder instability, which account for about 70% of shoulder disorders, and their incidence and severity are much higher than the familiar frozen shoulder. Beware of shoulder and elbow disorders caused by inappropriate exercise. It is commonly believed that the most common shoulder and elbow disorder is shoulder arthritis (i.e. “frozen shoulder”), which is a common disease among middle-aged and elderly people. In fact, the incidence of frozen shoulder is only about 5% to 15%. Rotator cuff injuries have the highest incidence of shoulder joint disorders. With age, excessive daily exertion, trauma and frequent shoulder abduction activities, rotator cuff injury is easily caused, which mainly manifests as shoulder pain, pressure pain, aggravation during activities, popping sound, and obvious limitation of shoulder joint function. Rotator cuff injuries are most common in men over the age of 40 and occur in the absence of obvious trauma. Once a rotator cuff injury occurs, it does not heal easily as the condition worsens. Unfortunately, however, most patients with rotator cuff injuries do not receive timely and proper treatment, resulting in an aggravation of the condition. Many people mistakenly believe that shoulder and elbow disease is frozen shoulder and treat rotator cuff injuries as frozen shoulder, which may cause rotator cuff injuries to continue to worsen and even develop into huge or irreparable rotator cuff tears, resulting in serious loss of shoulder joint function. For this reason, it is important to pay attention to shoulder and elbow joint disorders and be sure to develop a treatment plan based on the condition. Depending on the patient’s condition, shoulder and elbow disorders can be divided into non-surgical conservative treatment and surgical treatment. In general, conservative treatment is available for middle-aged and elderly patients, small tears with partial injury or mild symptoms, and early shoulder and elbow joint disease, but if conservative treatment is ineffective, or if the mirror image shows a rotator cuff rupture, surgical treatment is necessary. To protect the shoulder joint, it is best for office workers to stand up and relax every 45 minutes to prevent the muscles from staying stiff. For exercise, it is also advocated to act according to ability and need. Geriatric patients are suitable for walking and swimming, especially the water activities are very good way to relax. You also need to relax before working out, otherwise it is easy to do explosive movements when the muscles are very tight.
