Frozen shoulder is a chronic and specific inflammation of the shoulder capsule and its surrounding ligaments, tendons and bursae that is characterized by gradual pain in the shoulder, which is worse at night and progressively worsens, limiting the movement of the shoulder joint, gradually relieving after a certain point, and finally recovering completely. Studies have shown that the prevalence of frozen shoulder in the population is 2% to 5% and is more common in the 40-65 age group, with women being more likely than men (60:40). With the increasing prevalence of a sedentary lifestyle, the incidence of frozen shoulder is trending younger. What are the characteristics of frozen shoulder? One feature: shoulder pain is light during the day and heavy at night, often making it hard to sleep, and even at night, when there is no place to put your hands. Feature 2: Frozen shoulder tends to occur around the age of 50, so the disease is also known as the 50th shoulder. Feature 3: The onset of the disease is slow and the duration of the disease is long, usually within 1 year, but in the longer cases it can reach 1 to 2 years. The fourth characteristic is that the lesion is widespread, i.e., widespread pain, widespread functional limitation, and widespread pressure pain. The damage caused to the patient? 1.Slow and severe pain: Pain is the main symptom of frozen shoulder, and this symptom will gradually become obvious with the gradual aggravation of the disease, and eventually it will become persistent pain, which makes it impossible to sleep, and seriously affects our life. 2.Impact on daily life: Frozen shoulder is likely to cause pressure pain in the front, outside and back of the shoulder joint, or even to the whole arm, resulting in restriction of basic functions such as grasping, lifting and carrying. 3. Muscle atrophy: Because frozen shoulder can cause activity disorders that affect our daily life, any activity that involves the shoulder, such as shoulder flare, external rotation, posterior extension, etc., will cause pain, and in severe cases, the shoulder will be in internal rotation, and the muscles will be obviously atrophied and cannot continue to work. Exercise therapy for frozen shoulder patients Swimming exercise: Swimming is a good way to treat frozen shoulder. It is recommended to use breaststroke and backstroke, so that the muscles around the neck and shoulder joints can be moved, and it depends on your physical strength. Generally, 1-2 times a week, each time lasting 30 minutes is enough. Finger climbing wall: stand facing the wall, hold the wall with both hands, crawl your fingers up with the turn, practice lifting up, while observing which side is serious, and record the maximum height reached daily. Twice a day, more than 30 times each time. Bend and shake arms: bend forward 60 degrees at the waist, swing back and forth from the affected wall, with an increasingly good swing range. Twice daily, 30 times on each swing. Crossed shoulder patting: both walls are crossed and flung in front of the chest, both hands pat the opposite shoulder, alternating between the arms up and down, more than 30 times each time, practicing 2 times a day. Back body touching the back: two arms are stretched back, with the healthy side of the wrist, so that the affected side of the finger as far as possible up to touch the spine. Rotating arm movement: one hand crosses the waist, the other wall left rotating movement, first clockwise rotation 30 times, in counterclockwise rotation 30 times, change the opposite side to do the same movement, the arc of rotation is getting better.
