Test: Adduction and elevation of scapula, with a downward rotation (medial rotation of the inferior angle). The position of the scapula is obtained by placing the shoulder in 90° abduction and in sufficient medial rotation to move the scapula into the test position. The palm of the hand faces in a caudal direction
Pressure: Against the forearm, in a downward direction toward the table.
Test: The ability of the serratus to stabilize the scapula in a position of abduction and lateral rotation, with the arm in a position of approximately 120° to 130° of flexion.
Pressure: Against the dorsal surface of the arm, between the shoulder and elbow, downward in the direction of extension, and slight pressure against the lateral border of the scapula, in the direction of rotating the inferior angle medially.
Test movement: Facing a wall and with the elbows straight, the subject places both hands against the wall, either at shoulder level or slight above. To begin, the thorax is allowed to sag forward so that the scapulae are in a position of some adduction. The subject then pushes hard against the wall, displacing the thorax backward, until the scapulae are in a position of abduction.
Resistance: The thorax acts as resistance in this test
