Paraffin baths are used to treat subacute or chronic rheumatoid arthritis with joint stiffness and decreased ROM. What is the typical paraffin bath temperature?

• A. 90-100°F.
• B. 113-129°F.
• C. 140-150°F.
• D. 170-180°F.

Answer: (B)

Paraffin baths provide superficial heat to the joints, which helps loosen tissues, reduce pain, and improve range of motion in subacute to chronic rheumatoid arthritis. The wax is heated to a temperature that is warm enough to raise tissue temperature without causing burns, typically around the mid-range of a safe window. The commonly used target is about 125°F, which falls within the 113-129°F range and balances effective heating with safety, especially for joints that may be tender or have altered sensation. Temperatures much higher, like 140-150°F or 170-180°F, increase the risk of skin burns and tissue damage, while temperatures as low as 90-100°F may not provide a meaningful heating effect. This keeps the treatment effective while protecting sensitive RA joints.
