Impaired sensation or cognitive deficits can be caused by what type of therapy?

• A. CRYOtherapy
• B. Heat therapy
• C. Massage therapy
• D. Ultrasound

Answer: (A)

Cryotherapy is the modality most closely linked to impaired sensation because its effect is numbness in the treated area. Cold exposure slows nerve conduction and can cause skin numbness or reduced sensation. If a person already has impaired sensation or cognitive deficits, they may not notice overheating, frostbite, or tissue damage developing, which raises the risk of injury. While other therapies can carry risks (heat therapy can cause burns if sensation is impaired; ultrasound and massage have different safety considerations), the direct link to loss of protective sensation is most pronounced with cryotherapy, making it the best answer in this scenario.
