Which describes a therapeutic modality?

• A. A device or application that delivers a physical agent to the body for therapeutic purposes.
• B. A surgical procedure to repair tissue.
• C. A nutritional supplement.
• D. A pharmacologic drug.

Answer: (A)

Therapeutic modalities are interventions that use a device or method to deliver a physical agent to the body to produce a therapeutic effect, such as heat, cold, ultrasound, or electrical stimulation. This option fits because it describes a device or application delivering a physical agent for healing or functional improvement. The other categories aren’t considered modalities in this sense: a surgical procedure is an operative intervention, not a delivered physical agent; a nutritional supplement provides nutrition rather than a physical agent applied to tissues; a pharmacologic drug relies on chemical action rather than a physical modality applied externally.
