Which condition requires caution when applying cryotherapy?

• A. Excellent pain tolerance
• B. Good circulation
• C. Poor sensation
• D. Normal sensation

Answer: (C)

Cryotherapy safety hinges on sensory feedback. If a person has poor sensation, they can’t feel how cold the tissue is or when it starts to sting, numb, or burn, so they may develop tissue injury or frostbite without realizing it. This loss of protective sensation makes longer or more intense cooling risky, which is why poor sensation requires caution. In contrast, good or normal sensation provides the patient with warning signs to stop or shift treatment, and intact circulation helps tissue health, making the risk lower. In practice, with insensate skin you would use shorter application times, a barrier between the device and skin, and frequent checks for color, temperature, or numbness, stopping if any abnormal sensation or skin change occurs.
