Muscles Involved:[edit | edit source]

Patient Positioning[edit | edit source]

  • Patient is prone, head turned to non-test-side
  • test-side arm shoulder at 90° abduction and elbow in 90° flexion
  • For grades 0-2 the patient is seated with arm externally rotated (palm up) and arm supported on a flat surface such as a plinth ('gravity minimal' position)

Therapist Position[edit | edit source]

  • Stand at test side
  • Palpate shoulder adductor muscles

To Test[edit | edit source]

  • Patient to perform scapula adduction "lift tip of elbow towards the ceiling"
  • For grades 4 to 5, provide resistance over distal humerus in the direction opposite to scapular adduction [1]
  • Note:as with all resisted testing of vertebro-scapular muscles, the preferred resistance point is that which constitutes the longest lever as this more closely reflects the functional demands of the limb.
  • To satisfy grade 5 'normal muscle' performance criteria, the patient must have the ability to move through complete range of motion (active resistance testing) OR maintain an end point range (break testing) against maximum resistance.
