Which sensation is represented in the typical sensory response to cryotherapy?

• A. Intense cold
• B. Analgesia ( or numbness )
• C. Burning sensation
• D. Deep aching

Answer: (B)

Cryotherapy lowers tissue temperature, which slows nerve conduction velocity and reduces pain signaling. As cooling continues, the treated area often becomes numb because the sensory nerves transmit fewer pain signals and the local pain threshold is raised. This numbness, or analgesia, is the typical sensory response sought in cryotherapy. An initial intense cold sensation may be felt, and burning or deep aching can occur if exposure is excessive, but the standard therapeutic response is numbness.
