Which are the three types of PAMs?

• A. Massage, cold, and stretching
• B. Heat, Cold (cryotherapy), and Electric modalities
• C. Ultrasound, traction, and laser
• D. Exercise, ergonomics, and education

Answer: (B)

Physical Agent Modalities are treatments that use physical energy to influence tissues and pain. The three types typically recognized are thermal modalities (heat and cryotherapy) and electrical modalities. Heat raises tissue temperature to increase blood flow, improve tissue extensibility, and help with muscle relaxation and ROM. Cryotherapy lowers tissue temperature, which reduces blood flow, slows metabolism, decreases inflammation, and provides analgesia. Electrical modalities deliver electrical energy to modulate nerve signaling or muscle activity, offering pain relief, neuromuscular reeducation, and edema control. Other options mix manual therapy, ultrasound or traction, or non-PAM approaches like education, which aren’t categorized as these three PAM types.
