Which of the following is NOT a category of PAMS administration?

• A. Superficial thermal
• B. Deep thermal
• C. Electrotherapeutic
• D. Cryotherapy

Answer: (D)

PAMS modalities are grouped by how they affect tissue temperature and depth of penetration: superficial thermal modalities alter surface tissue temperature, deep thermal modalities reach deeper tissues, and electrotherapeutic modalities use electrical energy. Cryotherapy is a cooling method used to produce a temperature change, but it sits within the broader umbrella of superficial thermal modalities rather than forming its own standalone category. In other words, cryotherapy is a specific approach to cooling within the superficial thermal group, not a separate category like the broader groups of superficial thermal, deep thermal, or electrotherapy. The other options represent distinct, recognized categories, whereas cryotherapy is a type of superficial thermal modality.
