CTO Patient Evaluation & Measurement 4

Question 1

The 'neutral calcaneal stance position' (NCSP) is most accurately measured using which technique?

Accepted Answer

Goniometric measurement of the calcaneus relative to the supporting surface while the patient stands

Answer

NCSP is a weight-bearing measure obtained by bisecting the posterior calcaneus and measuring its angle relative to the floor while the patient stands in a neutral subtalar position.

Question 2

When documenting circumferential measurements for a custom spinal orthosis, measurements are typically recorded at which intervals along the torso?

Accepted Answer

Every 2 cm from the intended proximal to distal trim lines

Answer

Circumferential measurements taken every 2 cm across the intended orthosis coverage area allow accurate reconstruction of torso contour for custom fabrication.

Question 3

A patient scheduled for wrist-hand orthosis (WHO) fitting is assessed for intrinsic muscle tightness. Which test distinguishes intrinsic from extrinsic finger flexor tightness?

Accepted Answer

Bunnel-Littler test

Answer

The Bunnel-Littler test differentiates intrinsic tightness from joint contracture by comparing passive PIP flexion with the MCP in extension versus slight flexion.

Question 4

During evaluation for a thoracic hyperkyphosis orthosis, a patient's Cobb angle is measured at 62°. This value is used primarily to:

Accepted Answer

Select the appropriate pad placement to apply corrective three-point forces

Answer

The Cobb angle quantifies the deformity magnitude, and the apex and end-vertebrae locations guide the positioning of the three corrective pads in a hyperextension orthosis.

Question 5

A patient with diabetic peripheral neuropathy is being evaluated for a custom foot orthosis. The primary evaluation tool used to identify plantar pressure hot spots is:

Accepted Answer

In-shoe pedobarograph

Answer

In-shoe pedobarography maps dynamic plantar pressure distribution during walking, directly identifying high-pressure areas at risk for ulceration in neuropathic feet.
