COF Patient Assessment & Measurement 3

Question 1

When performing a manual muscle test (MMT) for orthotic planning, a grade of 3/5 indicates the muscle can:

Accepted Answer

Move through full ROM against gravity only

Answer

An MMT grade of 3/5 means the muscle can complete full range of motion against gravity but cannot overcome any additional resistance.

Question 2

A patient's skin assessment reveals stage 2 pressure injury under a previously worn orthosis. The FIRST step in the fitting process should be:

Accepted Answer

Document and refer to wound care before refitting

Answer

A stage 2 pressure injury requires wound care intervention and documentation before orthotic modification or refitting to prevent further tissue damage.

Question 3

Which measurement is taken to determine the correct length of a Lofstrand (forearm) crutch for a patient?

Accepted Answer

From the floor to 2 inches below the elbow flexed at 15-20 degrees

Answer

Lofstrand crutch length is measured from the floor to approximately 2 inches below the elbow when flexed at 15-20 degrees, positioning the forearm cuff correctly.

Question 4

During assessment, a patient exhibits clonus at the ankle. This finding suggests involvement of which neurological pathway?

Accepted Answer

Upper motor neuron

Answer

Clonus is a sign of upper motor neuron lesion causing hyperreflexia and loss of descending inhibitory control on the stretch reflex.

Question 5

To measure the circumference of a lower limb for a compression orthosis, measurements should be taken at:

Accepted Answer

Standard anatomical landmarks at consistent intervals

Answer

Circumferential measurements for compression orthoses must be taken at standard anatomical landmarks and consistent intervals to ensure graduated compression and accurate fitting.
