Study Notes
Scapular Abduction & Upward Rotation
- Grade 3: Supine position, stabilize the trunk, patient pushes arm forward "reaching for the ceiling"
- Muscles Involved: Serratus anterior, Pectoralis minor, upper and lower Trapezius
- Grade 4 & 5: Same position as grade 3, resistance applied to the distal humerus.
- Grade 2, 1, and Zero: Sitting position, avoid trunk rotation, patient pushes arm forward.
- Palpation: Mid-axillary adjacent to the inferior angle of the scapula.
- Serratus Anterior Push Up Test: Winging of the scapula indicates weakness.
Scapular (Shoulder) Elevation
- Grade 3: Sitting position, stabilize head, patient pulls shoulders upward.
- Muscles Involved: Trapezius, Levator scapulae, Rhomboids major and minor.
- Grade 4, 5: Same position as grade 3, resistance applied above the shoulder.
- Grade 2, 1, and Zero: Prone position, therapist supports the weight of the upper extremity, stabilize head, patient pulls shoulders towards the ears.
- Trapezius Palpation: Middle point from the inion to the acromion.
Scapular Adduction (Retraction)
- Grade 3: Prone position, stabilize contralateral thorax, patient brings arm up and adducts scapula toward the midline.
- Muscles Involved: Middle Trapezius, Rhomboids major and minor.
- Grade 4, 5: Same position as grade 3, resistance applied to the distal forearm
- Grade 2, 1, and Zero: Sitting position, avoid trunk rotation, patient pulls arm slightly backward and brings scapula back and in.
- Palpation: Medial border of the scapula and the vertebra above the spine of scapula (from T1-T5)
Scapular Depression and Adduction
- Grade 3: Prone position, arm over head 145 degrees shoulder elevation and abduction, forearm neutral with thumb pointing up, patient moves arm from the table as high as possible.
- Muscles Involved: Lower and middle Trapezius, Lattisimus dorsi, Pectoralis minor and major.
- Grade 4, 5: Same position as grade 3, resistance applied to the distal forearm, patient holds arm against resistance without pushing down.
- Other Points: The therapist should give instructions to "hold your arm" instead of "push down" to ensure adequate muscle engagement in the movement.
