NPTE-PT Gait, Balance, and Orthotics 2

Question 1

A patient with a right transtibial amputation demonstrates lateral trunk bending toward the prosthetic side during stance. What is the MOST likely cause?

Accepted Answer

Prosthetic shank too long

Answer

Lateral trunk lean toward the prosthetic side during stance is most commonly caused by a prosthetic shank that is too long, causing the patient to lean over it.

Question 2

During the swing phase of gait, a patient with a below-knee brace (AFO) exhibits toe drag. Which AFO adjustment would BEST correct this?

Accepted Answer

Add a dorsiflexion assist spring

Answer

A dorsiflexion assist spring in the AFO helps lift the foot during swing phase, preventing toe drag caused by inadequate dorsiflexion.

Question 3

Which Berg Balance Scale score BEST indicates a high fall risk in a community-dwelling older adult?

Accepted Answer

Below 41

Answer

A Berg Balance Scale score below 41 is associated with a significantly high fall risk in older adults.

Question 4

A patient with L4 nerve root dysfunction will MOST likely require which orthotic device?

Accepted Answer

AFO with dorsiflexion assist

Answer

L4 innervates the tibialis anterior (dorsiflexors); weakness causes foot drop, best managed with a dorsiflexion-assist AFO.

Question 5

During quiet standing, which system provides the PRIMARY sensory input for balance in a well-lit environment on a firm surface?

Accepted Answer

Proprioceptive/somatosensory

Answer

On a firm, stable surface, the proprioceptive/somatosensory system provides the dominant input for balance control.
