MMT Special Considerations 2

Question 1

When testing a patient with severe osteoporosis, which modification is most appropriate during MMT?

Accepted Answer

Use a shorter lever arm by placing resistance closer to the joint

Answer

Placing resistance closer to the joint shortens the lever arm, reducing torque and minimizing fracture risk in osteoporotic bones.

Question 2

A patient with acute DVT in the lower extremity requires MMT. Which is the safest approach?

Accepted Answer

Postpone lower extremity MMT until DVT is resolved or cleared by physician

Answer

Active lower extremity MMT with a DVT risks dislodging the thrombus, so testing should be deferred until medically cleared.

Question 3

Which condition most significantly invalidates standard MMT grades due to velocity-dependent resistance?

Accepted Answer

Spasticity

Answer

Spasticity produces velocity-dependent resistance that artificially inflates perceived muscle strength, making standard MMT grades unreliable.

Question 4

When performing MMT on a patient who is 32 weeks pregnant, which position should generally be avoided?

Accepted Answer

Supine

Answer

Supine positioning after 20 weeks of pregnancy risks supine hypotensive syndrome due to vena cava compression by the uterus.

Question 5

A patient with a grade 2/5 MMT score for hip flexion most likely demonstrates which functional ability?

Accepted Answer

Can move the hip through full ROM only in a gravity-eliminated position

Answer

Grade 2 indicates active movement through full ROM only when gravity is eliminated, such as in side-lying.
