MMT Clinical Applications 2

Question 1

A patient with a C5 spinal cord injury is being evaluated. Which muscle would you test to determine C5 motor function?

Accepted Answer

Elbow flexors (biceps brachii)

Answer

Elbow flexors (biceps brachii) are the key muscles for the C5 myotome in spinal cord injury assessment.

Question 2

During MMT of the hip abductors, a patient can hold the position against gravity but gives way with minimal resistance. What grade is assigned?

Accepted Answer

Grade 4-

Answer

Grade 4- indicates the muscle holds against gravity and tolerates minimal resistance but yields before moderate resistance is applied.

Question 3

When testing the serratus anterior, winging of the scapula during a wall push-up test most likely indicates weakness or paralysis due to injury of which nerve?

Accepted Answer

Long thoracic nerve

Answer

The long thoracic nerve innervates the serratus anterior; its injury causes medial scapular winging during pushing activities.

Question 4

A patient post-stroke has spasticity in the elbow flexors. Which modification is most important when performing MMT on this patient?

Accepted Answer

Apply resistance slowly to avoid triggering the stretch reflex

Answer

Applying resistance slowly helps avoid triggering the stretch reflex in spastic muscles, which would give a falsely lower grade.

Question 5

In Guillain-Barré syndrome, MMT findings typically show which pattern of weakness?

Accepted Answer

Distal > proximal, symmetric ascending

Answer

Guillain-Barré syndrome classically presents with symmetric ascending weakness that is more pronounced distally and progresses proximally.
