Which type of therapy uses a warm whirlpool, hot packs, paraffin baths, infrared lamps, and fluidotherapy?

• A. Cryotherapy
• B. Light therapy modalities
• C. Electrical modalities
• D. Thermotherapy

Answer: (D)

Thermotherapy is about applying heat to increase tissue temperature, which promotes vasodilation, speeds metabolic activity, relaxes muscles, reduces joint stiffness, and can improve tissue extensibility for stretching.

The modalities listed—warm whirlpool, hot packs, paraffin baths, infrared lamps, and fluidotherapy—are all methods of delivering heat to the body. Warm whirlpool and hot packs provide surface or superficial heating through contact with warm water or material; paraffin baths apply heat through melted wax to especially warm small joints; infrared lamps deliver radiant heat that heats tissue through infrared radiation; fluidotherapy circulates warmed particles to transfer heat while also providing gentle desensitization or touch therapy. Together, they are used to raise tissue temperature to prepare for movement, reduce pain, and facilitate healing.

Cryotherapy, electrical modalities, and light therapy modalities either use cold, electrical energy, or non-heat light energy, respectively, and do not fit this set of heating techniques.
