extension, goni, goni axis, Goniometry, moveable arm, ROM, shoulder, stable arm, test and measures

Oops we goofed! The video shows both the shoulder and elbow in extension, but you want to make sure the elbow is flexed to prevent passive insufficiency of the biceps brachii that could cause a restriction in extension ROM.

Placement and Positioning

Patient position: prone or sitting

Goniometer axis placement: lateral aspect of the center of humeral head or about 2.5 cm below the acromion process

Stationary arm placement: parallel to the midline of the trunk

Moveable arm placement: parallel to the lateral midline of the humerus pointing toward the lateral epicondyle of the humerus

Normal ROM

0-60°
