Which option is NOT a contraindication to thermotherapy?

• A. Acute conditions
• B. Pregnancy
• C. Deep vein thrombosis
• D. Exercise

Answer: (D)

Understanding thermotherapy contraindications helps you use heat safely. Heat should be avoided in acute conditions because increased blood flow and metabolic activity can worsen inflammation and swelling. It’s also avoided with deep vein thrombosis since warming can potentially increase clot activity or risk of embolism. Pregnancy is a precautionary/contraindicated scenario because overheating can affect the fetus, especially with abdominal heat applications. The one that is NOT a contraindication is exercising—heat can be used to warm up muscles, improve tissue extensibility, and promote blood flow around activity, provided the patient tolerates it and there are no other contraindications.
