COC Assessment & Evaluation 3

Question 1

Which assessment tool is specifically designed to evaluate the functional outcomes of upper limb prosthesis users?

Accepted Answer

DASH (Disabilities of the Arm, Shoulder and Hand) questionnaire

Answer

The DASH questionnaire is a validated outcome measure assessing physical function and symptoms in persons with upper extremity musculoskeletal conditions and prosthesis users.

Question 2

Subtalar neutral position is clinically important in orthotic casting because it:

Accepted Answer

Represents the point of minimal stress on periarticular structures for cast-based prescription

Answer

Casting in subtalar neutral captures the foot in its theoretically most balanced position, reducing stress on soft tissues and forming the basis for functional foot orthotics.

Question 3

A positive Romberg test (increased sway with eyes closed vs. open) indicates that a patient is relying primarily on which sensory system for balance?

Accepted Answer

Vision, with deficient somatosensory or vestibular input

Answer

When closing the eyes dramatically worsens balance, it reveals dependence on visual input to compensate for deficits in somatosensory or vestibular systems.

Question 4

During a lower limb prosthetic evaluation, lateral trunk bending over the prosthetic side in mid-stance most commonly indicates:

Accepted Answer

Prosthetic limb is too short, or the socket is abducted, or abductor weakness

Answer

Lateral trunk lean toward the prosthetic side reduces the demand on the hip abductors or compensates for a short limb by lowering the center of mass.

Question 5

The L-code system in the United States is used in O&P for:

Accepted Answer

Billing and coding of orthotic and prosthetic devices for Medicare reimbursement

Answer

The HCPCS Level II L-codes are the standard billing codes for orthotic and prosthetic devices used in Medicare and Medicaid reimbursement claims.
