✍️ 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 scenario represents a violation of the Certified Orthotic Technician code of professional conduct?
Misrepresenting qualifications is a serious violation that undermines public trust.
3. Which muscle group is primarily responsible for controlling the rate of foot drop during the loading response phase?
The tibialis anterior eccentrically contracts during loading response to control the rate at which the foot lowers to the ground.
4. Which nerve injury would most likely require a low-profile dynamic MCP extension orthosis?
Radial nerve injury at the spiral groove causes wrist drop and loss of MCP extension, requiring a dynamic orthosis to restore that function.
5. When conducting a risk assessment for CTO operations, which factor should receive the HIGHEST priority?
The probability and severity of potential harm are the primary factors in risk assessment.
6. What tool is commonly used to make precise device adjustments?
Many orthotic devices are made from thermoplastic materials that can be molded and reshaped when heated. A heat gun or oven provides controlled heat, allowing the Certified Orthotic Technician to soften these materials and make precise adjustments to the device's shape, contours, or angles. This capability is essential for customizing the orthotic to the patient's unique anatomy and addressing specific pressure points or functional requirements.
