Isometric Strength Test Shoulder Rhomboids

For all Manual Muscle testing the following grading scale will be used: 5/5 the patient can hold against full resistance, 4/5 the patient can hold against moderate resistance, 3/5 the patient cannot hold against any resistance but can complete the motion against gravity. There will be no grading’s below a 3/5 for this population. Position the patient lying on the table in a prone position with their arms in an extended “T” position with their thumbs pointed down towards the ground. Stabilize the scapula with one hand and place the other on the distal arm. While remaining in that position, instruct the patient to actively hold the position and not let you push them down. Perform a break test by applying a downward force to the arm. Note the grading of strength and any presence of pain with the motion.
