Adhesive capsulitis (AC), also known as frozen shoulder, is a condition associated with shoulder pain and stiffness. [1] It is a common shoulder ailment that is marked by pain and a loss of range of motion, particularly in external rotation. [3] There is a loss of the ability to move the shoulder, both voluntarily and by others, in multiple ...
The scapula plays an important role in shoulder impingement syndrome. [8] It is a wide, flat bone lying on the posterior thoracic wall that provides an attachment for three different groups of muscles. The intrinsic muscles of the scapula include the muscles of the rotator cuff- the subscapularis, infraspinatus, teres minor and supraspinatus. [9]
Medical history (the patient tells the doctor about an injury). For shoulder problems the medical history includes the patient's age, dominant hand, if injury affects normal work/activities as well as details on the actual shoulder problem including acute versus chronic and the presence of shoulder catching, instability, locking, pain, paresthesias (burning sensation), stiffness, swelling, and ...

The rotator cuff muscles of the shoulder produce a high tensile force, and help to pull the head of the humerus into the glenoid cavity. The glenoid cavity is shallow and contains the glenoid labrum which deepens it and aids stability. With 120 degrees of unassisted flexion, the shoulder joint is the most mobile joint in the body.

[2] Furthermore, a patient can also be tested for weakness when asked to raise the arm. [2] The deltoid extension lag sign test is one way to evaluate the severity of the muscle weakness.
Explicitly, LGMD preferentially affects muscles of the hip girdle, thigh, shoulder girdle, and/or upper arm. [ 8 ] [ 6 ] The muscle weakness is generally symmetric. [ 11 ] Usually, the hip girdle is the first area to exhibit weakness, [ 2 ] manifesting as difficulty walking, going up and/or down stairs, rising from a chair, bending at the waist ...
