Question 1

During lumbar mechanical traction, a patient reports increased lower extremity paresthesias bilaterally. The BEST immediate action is:

Accepted Answer

Stop the traction immediately and reassess

Answer

Bilateral worsening neurological symptoms during traction may indicate increased spinal cord or cauda equina compromise, requiring immediate cessation.

Question 2

Which electrode configuration in electrical stimulation results in the deepest current penetration between electrodes?

Accepted Answer

Monopolar — active electrode over target, dispersive electrode distant

Answer

In monopolar configuration, current flows from the small active electrode through deep tissues to the large dispersive electrode placed at a distance, maximizing depth.

Question 3

A therapist is selecting a prosthetic foot component for a K3-level transtibial amputee who wants to return to jogging. Which foot is MOST appropriate?

Accepted Answer

Energy-storing/returning carbon fiber foot

Answer

Energy-storing and returning (ESR) carbon fiber feet store energy during loading and release it at push-off, enabling higher activity levels including jogging.

Question 4

Which parameter of therapeutic ultrasound should be INCREASED to treat a superficial scar (1 cm depth) and maximize tissue heating?

Accepted Answer

Frequency from 1 MHz to 3 MHz

Answer

3 MHz ultrasound absorbs more rapidly in superficial tissues (1–2 cm), producing more heat at that depth compared to 1 MHz.

Question 5

A patient using axillary crutches complains of tingling in the ring and little fingers. The MOST likely cause is:

Accepted Answer

Excessive weight bearing through the axillary pad compressing the brachial plexus

Answer

Weight bearing through the axillary pad compresses the radial nerve or brachial plexus; however, the ring/little finger pattern specifically points to ulnar nerve or C8/T1 involvement from pad pressure.
