CPO Patient Management & Follow-Up 3

Question 1

A bilateral lower limb amputee returns for a follow-up reporting fatigue during ambulation. Which energy expenditure factor should the practitioner evaluate first?

Accepted Answer

Prosthetic foot category and dynamic response

Answer

Prosthetic foot selection directly influences energy return and metabolic cost of ambulation in bilateral amputees.

Question 2

Which patient complaint during follow-up most strongly indicates the need for a complete socket replacement rather than a modification?

Accepted Answer

Total contact loss with >6 socks needed for fit

Answer

Requiring more than 5 ply of socks indicates significant volume loss that warrants fabricating a new socket rather than temporary accommodation.

Question 3

During a follow-up with a patient using a myoelectric upper limb prosthesis, the practitioner observes delayed terminal device response. The most likely cause is:

Accepted Answer

Inadequate electrode contact with skin

Answer

Poor electrode-skin contact is the most common cause of delayed or inconsistent myoelectric signal response.

Question 4

A patient at a 12-month follow-up reports phantom limb pain that has worsened since initial fitting. The appropriate practitioner response is:

Accepted Answer

Document the complaint and refer to the treating physician

Answer

Worsening phantom limb pain requires physician referral for medical management, as it falls outside the prosthetist's scope to treat.

Question 5

When conducting a follow-up gait analysis for a patient with a transtibial prosthesis, a shortened step length on the sound side is most likely caused by:

Accepted Answer

Excessive prosthetic foot plantarflexion resistance

Answer

Excessive plantarflexion resistance at the prosthetic ankle limits forward progression, causing a shortened contralateral step.
