Question 1

Which digital scanning method captures a 3D model of a patient's foot by projecting structured light patterns onto the surface?

Accepted Answer

Structured-light 3D scanning

Answer

Structured-light 3D scanning projects patterned light and uses cameras to calculate surface geometry, producing accurate foot models for orthotic fabrication.

Question 2

In CAD/CAM orthotic fabrication, what does the 'CAM' component specifically refer to?

Accepted Answer

Computer-aided manufacturing

Answer

CAM stands for computer-aided manufacturing, which translates the digital design into machine instructions that drive CNC milling equipment.

Question 3

A practitioner uses pressure mapping insoles during gait analysis. What does a high-pressure 'hot spot' under the first metatarsal head typically indicate?

Accepted Answer

Excessive forefoot pronation or hallux limitus

Answer

Elevated plantar pressure under the first metatarsal head often signals hallux limitus, forefoot pronation, or functional limb length discrepancy causing forefoot overload.

Question 4

When entering orthotic orders into an Electronic Health Record (EHR), which element is legally required to satisfy HIPAA documentation standards?

Accepted Answer

Unique patient identifier linked to the clinical note

Answer

HIPAA requires that protected health information be linked to a unique patient identifier within the medical record to ensure accurate tracking and privacy compliance.

Question 5

Which software feature in orthotic design programs allows the clinician to virtually add a metatarsal pad to a digital foot model before milling?

Accepted Answer

Parametric modification

Answer

Parametric modification tools let the clinician adjust specific design parameters — such as pad height, location, and taper — directly on the digital model.
