Scapulohumeral reflex

The Scapulohumeral reflex (or ankylosing spondylitis reflex, also known as the Scapulohumeral joint reflex or ankylosing spondylitis reflex) is one of the most common reflexes in the human body. It manifests itself when the muscles of the shoulder and shoulder blade contract when the arm is in a relaxed state.

The Scapulo-Pleural joint reflex occurs when pressing on the shoulder area. This causes the muscles of the shoulder blade and shoulder to contract. This reflex is important for maintaining balance and coordination of movements in the upper body.

There are various reasons why this reflex may be impaired. For example, this may occur due to damage to the nerves that control muscles, or due to diseases such as Parkinson's disease or multiple sclerosis. Impairment of this reflex can lead to various problems such as loss of balance, difficulty walking and other problems with coordination of movements.

To diagnose this reflex, it is necessary to conduct special tests in which the patient is asked to raise his arm up and then slowly lower it. If the scapulopleural joint reflex is impaired, the arm will drop faster than normal.

Treatment for scapulohumeral joint reflex disorder may include various methods such as physical therapy, massage, stretching exercises and other rehabilitation methods. In some cases, surgery may be required to restore muscle function.

The scapulohumeral reflex is an unconditioned reflex. It also has another name: the ankylosing spondylitis reflex, or the scapular-clavicular reflex. This is a physiological process of closure of the ulnar nerve in response to irritation by one of the vertebrae of the shoulder girdle. This happens when you raise your hand. As a result, nervous
