Hydrocollator packs are an example of which category of therapy?

• A. Deep tissue heating
• B. Superficial heat
• C. Cryotherapy
• D. Electrical stimulation

Answer: (B)

Hydrocollator packs deliver moist heat to the body’s surface, raising temperature mainly in the superficial tissues (roughly 1–2 cm deep). That makes them a superficial heat therapy, used to relax muscle, improve tissue elasticity, and ease pain before stretching or manual work. They aren’t cooling treatments (cryotherapy) and aren’t used for heating deep tissues—deeper heating modalities include methods like ultrasound or diathermy, and electrical stimulation is a different type of therapy altogether.
