Frozen shoulder can occur in young people, and the percentage of attacks is not small, especially in today’s society, where many young people suffer from frozen shoulder due to the heavy use of smartphones and computers. There are several common cases as follows: 1) trauma to the shoulder joint due to strenuous activity or trauma, which may lead to the onset of frozen shoulder during the recovery process; 2) cold shoulder due to inadequate clothing, which may lead to frozen shoulder; 3) prolonged sitting and standing with the head down, playing with cell phones and computers, which may also lead to frozen shoulder. Once a patient develops frozen shoulder, he or she may experience shoulder pain and a significant restriction of movement. In this case, it is important to remove the above-mentioned triggering factors as soon as possible and actively cooperate with the doctor to do the corresponding treatment.
