Frozen shoulder: commonly known as “fifty shoulders”, or “shoulder condensation”. It is common in women and usually occurs around the age of 50. In recent years, more and more young people are suffering from frozen shoulder. In mild cases, it can affect rest, often waking up with pain at night; in severe cases, it can affect daily life, such as being unable to comb your hair and tie your belt, sometimes feeling weakness in your arms, not being able to pick up the pot when cooking, not being able to turn the steering wheel when driving, and in more severe cases, the shoulder joint cannot move. The quality of daily life is seriously affected. Patients often have the following misconceptions in their daily exercise. One of the misconceptions: “You should exercise harder and harder after shoulder pain, the harder the better”, and “If you don’t practice and don’t exercise, you will develop to the point that you can’t move”. As a result, the more you exercise, the more powerful the injury becomes, and the more the pain gets worse. Qi Feng, Department of Anesthesiology, Qilu Hospital, Shandong University
