The Impact of Arthroscopic Capsular Release in Patients with Primary Frozen Shoulder on Shoulder Muscular Strength

Table 1

The assessment of range of motion, function, and muscle strength of flexors muscle of the shoulder (FFLX), abductors (ABD), and external (ER) and internal rotators (IR) of the operated and healthy shoulder after minimum two-year follow-up.
