COC Rehabilitation & Outcomes

Question 1

What is the primary goal of pre-prosthetic rehabilitation following lower limb amputation?

Accepted Answer

Residual limb conditioning, contracture prevention, and upper body strengthening

Answer

Pre-prosthetic rehab focuses on residual limb shaping, preventing contractures, maintaining cardiovascular fitness, and building upper body strength for transfers.

Question 2

Phantom limb pain (PLP) is most effectively addressed as a first-line intervention with:

Accepted Answer

Mirror therapy or graded motor imagery

Answer

Mirror therapy and graded motor imagery use visual feedback to remap cortical representation, reducing phantom limb pain in many patients.

Question 3

The most common complication leading to prosthetic rehabilitation failure in the early post-fitting phase is:

Accepted Answer

Residual limb skin breakdown due to poor socket fit

Answer

Skin breakdown from pressure and shear at the socket interface is the leading cause of interrupted prosthetic rehabilitation and device non-use.

Question 4

Which exercise is contraindicated for a transfemoral amputee due to the risk of promoting a hip flexion contracture?

Accepted Answer

Prolonged sitting in hip flexion without prone positioning to counterbalance

Answer

Prolonged sitting shortens hip flexors; without regular prone lying to stretch them, transfemoral amputees develop hip flexion contractures that impair prosthetic gait.

Question 5

K-level classification is primarily used to determine prosthetic prescription by predicting:

Accepted Answer

Functional rehabilitation potential and activity level

Answer

K-levels (K0–K4) guide component selection by estimating the patient's functional rehabilitation potential and anticipated activity demands.
