✍️ Sample CTO Questions & Answers
1. Which measurement is most important when sizing a prefabricated wrist orthosis?
Wrist circumference is the primary sizing parameter used by most prefabricated orthosis manufacturers to ensure proper fit and support.
2. Which of the following best describes the purpose of a corrective action plan (CAP) following a documentation audit finding?
A CAP addresses the root cause of a deficiency and documents steps taken to prevent the issue from recurring, supporting continuous quality improvement.
3. Which thermoplastic material is most appropriate for fabricating a rigid ankle-foot orthosis (AFO) requiring high durability and resistance to deformation under load?
Polypropylene is the standard rigid thermoplastic for AFOs due to its high durability, stiffness, and resistance to deformation under body weight.
4. Which scenario represents a violation of the Certified Orthotic Technician code of professional conduct?
Misrepresenting qualifications is a serious violation that undermines public trust.
5. A practitioner writes a prescription for a 'custom-fabricated AFO.' The work order arrives without a diagnosis code. What should the technician do?
Complete documentation including diagnosis codes is required before fabrication to ensure medical necessity compliance and proper billing.
6. A patient scheduled for wrist-hand orthosis (WHO) fitting is assessed for intrinsic muscle tightness. Which test distinguishes intrinsic from extrinsic finger flexor tightness?
The Bunnel-Littler test differentiates intrinsic tightness from joint contracture by comparing passive PIP flexion with the MCP in extension versus slight flexion.
