MMT Lower Extremity Testing 5

Question 1

When bilaterally comparing MMT results for hip abductors, a finding of 4/5 on one side compared to 5/5 on the other is best interpreted as:

Accepted Answer

Mild unilateral weakness that may contribute to a Trendelenburg gait

Answer

Normal bilateral variation and clinically insignificant

Answer

Severe pathology requiring immediate imaging

Answer

Grade 4 is the maximum achievable grade in the clinical setting

Question 2

Which patient position is used to test the popliteus muscle's contribution to knee internal rotation?

Accepted Answer

Prone with knee flexed to 90°

Answer

Supine with knee extended

Answer

Side-lying with knee flexed to 45°

Answer

Seated with knee at 90°

Question 3

During MMT of the adductor group, which muscle is best isolated by positioning the hip in slight flexion rather than neutral?

Accepted Answer

Pectineus

Answer

Adductor longus

Answer

Adductor magnus (posterior part)

Answer

Gracilis

Question 4

What is the clinical significance of clonus detected at the ankle during a lower extremity MMT session?

Accepted Answer

Indicates upper motor neuron pathology and is a contraindication to standard MMT resistance

Answer

Indicates Grade 0 muscle strength

Answer

Suggests lower motor neuron lesion

Answer

Confirms that the patient is exaggerating symptoms

Question 5

A runner presents with inability to perform a single-limb heel rise and weakness on plantar flexion MMT. The most likely involved nerve is:

Accepted Answer

Tibial nerve

Answer

Common peroneal nerve

Answer

Femoral nerve

Answer

Obturator nerve

Question 6

Which of the following scenarios correctly represents Grade 2+ (2+) on the MMT scale for knee flexion?

Accepted Answer

Partial ROM against gravity

Answer

Full ROM in gravity-eliminated position with slight resistance tolerated

Answer

Full ROM against gravity with no resistance

Answer

Palpable contraction without movement

Question 7

During MMT of the extensor digitorum longus, resistance is applied to the:

Accepted Answer

Dorsum of the proximal phalanges of toes 2–5

Answer

Plantar surface of the distal phalanges

Answer

Dorsum of the fifth metatarsal

Answer

Posterior calcaneus
