Paraffin therapy is best described as which type of modality?

• A. Deep thermal modality
• B. Electrical modality
• C. Superficial modality
• D. Mechanical modality

Answer: (C)

Parafin therapy is best described as a superficial heating modality. It delivers heat to the skin and the immediate underlying tissues through conduction from the melted wax. The heating effect stays near the surface (limited depth), typically affecting skin and subcutaneous tissues rather than reaching deeper muscles. It’s not electrical or mechanical in nature, which is why it’s classified away from electrical stimulation and mechanical modalities. The superficial heating can help increase tissue pliability and reduce joint stiffness in exposed areas like the hands and feet, without producing deep tissue heating.
