MMT Testing Procedures 2

Question 1

When testing a muscle against gravity, the patient is placed so that the body segment moves through its range in which plane?

Accepted Answer

Vertical

Answer

Against-gravity testing positions the segment so movement occurs in a vertical plane, requiring the muscle to work against the full effect of gravity.

Question 2

Which MMT grade is assigned when a patient can move a body segment through full ROM in a gravity-eliminated position but cannot hold against any manual resistance?

Accepted Answer

Grade 2

Answer

Grade 2 (Poor) indicates full ROM is achieved only when gravity is eliminated and no additional resistance is overcome.

Question 3

During manual muscle testing, a 'break test' is best described as:

Accepted Answer

Applying resistance at end range until movement is broken

Answer

A break test involves placing the segment at end range and applying force until the patient can no longer hold the position, allowing assessment of isometric strength.

Question 4

For which MMT grade does the examiner apply minimal resistance throughout the full range of motion?

Accepted Answer

Grade 4

Answer

Grade 4 (Good) is defined as the ability to complete full ROM against gravity and tolerate moderate resistance, but minimal resistance applied throughout still falls within the Grade 4 range description.

Question 5

What is the PRIMARY reason the examiner must stabilize the proximal segment during MMT?

Accepted Answer

To prevent substitution by adjacent muscles

Answer

Proximal stabilization prevents compensatory movements and substitution patterns that would give a falsely elevated muscle grade.
