Study Notes
Muscle Testing for Shoulder Flexion
- The coracobrachialis muscle is considered an accessory muscle during shoulder flexion.
- The range of motion (ROM) for shoulder flexion is 90°.
Therapist's Position and Patient Instructions
- The therapist should stand at the patient's side during the muscle test for shoulder flexion.
- The patient should be instructed to flex their shoulder against gravity.
Muscle Grading Criteria
- Grade 5 (Normal) muscle test requires full range of motion against gravity and maximum resistance.
- A patient who completes the test range of 90° but tolerates no resistance is graded 3 (Fair).
- A patient who completes partial range of motion as this is against gravity during shoulder flexion muscle testing is graded 2 (Poor).
Primary Muscle and Substitution
- The anterior deltoid muscle is primarily responsible for shoulder flexion.
- If the patient attempts to flex the shoulder with the biceps brachii by first externally rotating the shoulder, the biceps brachii is being substituted for shoulder flexion.
- If the patient attempts substitution with the pectoralis major, it results in horizontal adduction.
Alternate Test and Patient Positioning
- If the patient is unable to sit, the alternate test for Grades 2, 1, and 0 in shoulder flexion can be performed with the patient in a supine position.
- For Grade 1 (Trace) in shoulder flexion muscle testing, the patient's arm should be positioned in horizontal abduction.
- For Grade 2 (Poor) in shoulder flexion, the arm should be kept in adduction to avoid attempted substitution by the biceps brachii.
Muscle Characteristics
- The coracobrachialis muscle cannot be isolated, nor is it readily palpable.
