Video Link

Background/Purpose

Shoulder abduction primarily takes place due to the action of the deltoid muscle. There are three portions of the deltoid muscle: Anterior , Middle and Posterior.
The muscle is innervated by the Axillary nerve which originates from the C5-6 nerve root.

Procedure

Subject is seated on with the test arm raised to 60-90 degrees . The opposite shoulder is stabilized by the clinician. The clinician applies a downward force on the test shoulder. Subject should be able to maintain position against full pressure.
The clinician instruction to the patient is "Raise your elbow,. Hold it. Don't let me push it down."
Grade 5: Complete ROM and hold against maximal resistance.
Grade 4: Complete ROM and holds against moderate resistance but end point may not be firm.
Grade 3: Completes ROM with no manual resistance. In this case the clinician only cups the elbow for support. Patient instruction: "Bend your elbow."
Grade 2: Completes a partial ROM while supine.
Garde 1: The examiner can palpate a contractile response.
