Palsy of the suprascapular nerve may be easily overlooked in the differential diagnosis of the painful shoulder. Although the diagnosis is well documented in the literature, opinion is still divided regarding its etiology and treatment. This case report offers an example of successful nonoperative management of a suprascapular nerve palsy which followed an acute episode of muscular stress in a young male athlete.

The strength of active flexion/extension and supination/pronation was measured isokinetically in 60 right-hand-dominant nonathletic men. They were equally divided into a younger group (20 to 30 years) and an older group (50 to 60 years) with moderate occupational and spare-time activity levels. Peak torque, work, power, and the angle of peak torque production were measured bilaterally at a slow (90 degrees/sec) and a fast (180 degrees/sec) speed of movement. Although highly significant differences were found between the young and older groups in flexion and extension, no age-related differences were found in supination and pronation. The dominant side had significantly higher levels of peak torque, work, and power in flexion; however, no significant differences were detected in peak torque for extension, supination, and pronation. Isokinetic peak torque and work were greater at the slower speed as opposed to power, which was significantly greater at the faster speed with the exception of pronation movement. With regard to the angle where peak torque was achieved, significant differences were detected between groups, which suggests that age appears to affect where in the range of motion peak torque is produced.
