Pendulum (Codman's) Exercises Are Used Most Effectively

Pendulum (Codman's) exercises are used most effectively:

A) As a grade II oscillation technique to inhibit pain and maintain mobility.
B) As a strengthening exercise when a weight is held in the hand or placed around the wrist.
C) To stretch the shoulder musculature and increase range of motion (ROM) when a patient does not have antigravity control of shoulder movement.
D) As a grade III distraction technique to increase ROM when mobility of the scapula is normal but there is chronic stiffness of the glenohumeral joint.
