II. Exam: Normal range of motion
- Abduction: 150 degrees
- Adduction: 30 degrees
- Forward flexion: 150-180 degrees
- Extension: 45-60 degrees
- Rotation (test with elbow flexed to 90 degrees, see Apley's Scratch Test)
- Overhead sports (e.g. baseball, swimming) athletes have greater external rotation and restricted internal rotation
- External Rotation: 90 degrees
- Internal rotation: 70-90 degrees
III. Exam
- Test Active and Passive Range of Motion
- Test Apley Scratch Test
- Technique
- Compare both sides
- Measure individual angles (goniometer)
IV. Interpretation
- Passive range of motion loss (test if active range of motion abnormal)
- Loss of active range of motion, but intact passive range of motion
- Rotator Cuff Tear or Shoulder Impingement (painful arc in >60 degrees abduction)
