MMT Lower Extremity Testing 3

Question 1

During MMT of the gluteus maximus, what motion is being resisted?

Accepted Answer

Hip extension

Answer

The gluteus maximus is the primary hip extensor and is tested in prone with resistance applied to the posterior thigh.

Question 2

A patient in side-lying moves their lower extremity through full ROM in the gravity-eliminated plane. What grade is recorded?

Accepted Answer

Grade 2

Answer

Grade 2 (Poor) is assigned when the patient completes full ROM only in a gravity-eliminated position.

Question 3

Which muscle group is primarily responsible for subtalar inversion and is tested by resisting foot inversion in plantarflexion?

Accepted Answer

Tibialis posterior

Answer

Tibialis posterior is the primary subtalar invertor and is tested by applying resistance to the medial forefoot during inversion with plantarflexion.

Question 4

When assigning a grade of 4- (minus) versus 4 (grade 4) in MMT, what is the determining factor?

Accepted Answer

Amount of resistance tolerated relative to expected normal

Answer

A grade modifier (+ or −) reflects slight variations in resistance tolerance or ROM completion relative to the standard grade definition.

Question 5

Which position is used to gravity-eliminate hip adduction for a Grade 2 test?

Accepted Answer

Side-lying with test limb lowermost

Answer

Placing the test limb lowermost in side-lying allows the adductors to move the limb toward the upper limb without lifting against gravity.
