CPT Patient Assessment & Clinical Evaluation 4

Question 1

When assessing hip flexion contracture in a transfemoral amputee, the Thomas Test is performed. A positive result of 20 degrees indicates:

Accepted Answer

A contracture that will require significant socket flexion to accommodate

Answer

A 20-degree hip flexion contracture detected by the Thomas Test must be accommodated by building initial flexion into the transfemoral socket to prevent lumbar lordosis and gait deviations.

Question 2

The Houghton Scale is a validated outcome measure used specifically to assess:

Accepted Answer

Community integration and prosthesis use frequency in lower limb amputees

Answer

The Houghton Scale measures prosthesis use and community ambulation by asking about frequency, terrain management, and assistive device use.

Question 3

A skin fold or wrinkle in the posterior proximal socket of a transtibial prosthesis during stance phase most commonly indicates:

Accepted Answer

Socket that is too large for the residual limb

Answer

Skin folds forming posteriorly during weight-bearing indicate excess socket volume, meaning the socket is too large and needs adjustment to restore intimate fit.

Question 4

In clinical evaluation of a pediatric amputee, which growth-related factor must be regularly reassessed?

Accepted Answer

Residual limb length relative to the contralateral limb due to overgrowth or growth plate effects

Answer

Children experience differential limb growth; bony overgrowth at the residual limb tip and length discrepancies with the contralateral limb require frequent reassessment and prosthetic modification.

Question 5

During assessment of a patient's prosthetic gait, you observe vaulting on the sound side. This compensatory motion most likely results from:

Accepted Answer

Prosthetic limb that is too long or insufficient knee flexion during swing

Answer

Vaulting (rising on tiptoe of the sound foot) is typically a compensatory strategy to clear a prosthetic limb that is functionally too long or lacks adequate swing-phase knee flexion.
