MMT Clinical Applications 3

Question 1

A patient with lateral epicondylitis is being assessed. Which MMT finding would most directly support this diagnosis?

Accepted Answer

Weakness of wrist extensors with pain on resisted wrist extension

Answer

Lateral epicondylitis involves the common extensor origin; resisted wrist extension reproduces pain and may reveal extensor weakness.

Question 2

Which MMT position best isolates the middle trapezius while minimizing upper trapezius substitution?

Accepted Answer

Prone with shoulder at 90° abduction and elbow extended, resisting horizontal adduction

Answer

Prone horizontal abduction at 90° with elbow extended targets middle trapezius for scapular retraction while reducing upper trapezius involvement.

Question 3

A patient with Duchenne muscular dystrophy uses a Gowers' maneuver to rise from the floor. This sign primarily reflects weakness of which muscle group?

Accepted Answer

Hip extensors and knee extensors

Answer

Gowers' maneuver compensates for weak hip extensors (gluteus maximus) and knee extensors (quadriceps) by using the arms to 'walk up' the thighs.

Question 4

During cervical spine assessment, weak shoulder shrug on MMT combined with weak head rotation to the opposite side suggests involvement of which structure?

Accepted Answer

Spinal accessory nerve (CN XI)

Answer

The spinal accessory nerve innervates both the trapezius (shoulder shrug) and sternocleidomastoid (head rotation to opposite side).

Question 5

When testing the iliopsoas in a patient with a recent hip replacement, which modification is most important for safety?

Accepted Answer

Avoid hip flexion beyond 90° to prevent dislocation risk

Answer

Post-hip replacement precautions typically restrict hip flexion beyond 90° to prevent prosthetic dislocation during the healing phase.
