Goniometry: Shoulder Internal & External Rotation
Contents
Anatomical Movement
Shoulder internal rotation (IR)
Shoulder external rotation (ER)
Testing position
Patient is supine with the shoulder abducted to 90 degrees and the length of the humerus on the test side is supported on the plinth
Forearm is in neutral position
Goniometer Placement
AXIS LOCATION | STATIONARY ARM | MOVEMENT ARM |
---|---|---|
olecranon process of the ulna | perpendicular to the floor (vertical) | in line with the ulnar side of the forearm from the axis point to the ulnar styloid process |
Expected Findings
Expected range of motion for IR is 0- 70 degrees.
Expected range of motion for ER is 0- 90 degrees[1]
