MMT Upper Extremity Testing 3

Question 1

Which muscle is specifically tested when the examiner resists adduction of a horizontally abducted arm with the elbow extended?

Accepted Answer

Pectoralis major (sternal fibers)

Answer

The sternal fibers of pectoralis major perform horizontal adduction from a horizontally abducted position, making this the ideal test position.

Question 2

What finding would you expect when testing a muscle graded 1 (Trace) on MMT?

Accepted Answer

Visible or palpable contraction with no movement

Answer

Grade 1 (Trace) indicates a visible or palpable muscle contraction but insufficient force to produce joint movement.

Question 3

During MMT of the triceps, if the patient is tested in the gravity-eliminated plane, where is the arm positioned?

Accepted Answer

Shoulder at 90° flexion, testing elbow extension horizontally

Answer

With the shoulder flexed to 90°, elbow extension occurs in the horizontal plane, eliminating gravity for a Grade 2 triceps test.

Question 4

The 'empty can' position used in some MMT protocols tests which muscle?

Accepted Answer

Supraspinatus

Answer

The empty can test (arm at 90° in scapular plane, internally rotated) loads the supraspinatus and is used alongside MMT.

Question 5

When grading finger flexors, which grade indicates the patient can flex the fingers through full ROM against gravity but not against any added resistance?

Accepted Answer

Grade 3

Answer

Grade 3 (Fair) signifies full range of motion against gravity with no additional resistance.
