The shoulder joint check includes the following aspects: First, mobility. The shoulder joint is the largest and most complex joint mobility of the whole body, which can be forward flexion, back extension, abduction, supination, internal rotation, and external rotation, which is the mobility check. If there are related diseases, especially frozen shoulder, there will be limitation in all directions. Secondly, shoulder joint muscle strength check. The shoulder joint is divided into abduction, supination, posterior extension, internal rotation and external rotation, and these movements in each direction are controlled by different muscles, such as 0 degree abduction and 90 degree adduction, and resistance test should be performed at the same time, which can clarify which muscles have decreased muscle strength at this time. Third, special tests, such as Jobe’s sign, Neer’s sign, Napoleon’s test, these special tests are to check the related special diseases.
