What does electrotherapy mean?

• A. The application of heat to the skin
• B. The use of magnetic fields in therapy
• C. The use of electrical devices for therapeutic benefits
• D. The study of electricity in physics

Answer: (C)

Electrotherapy means using electrical energy delivered through devices to produce therapeutic effects in the body. It’s about applying electrical stimulation to nerves, muscles, or tissues to help relieve pain, reduce muscle spasm, promote healing, or improve circulation. This is different from applying heat to the skin (thermotherapy), which uses warmth for Treatment, or from using magnetic fields in therapy, or from the study of electricity in physics, which is about understanding electrical principles rather than applying them for healing. In practice, electrotherapy includes modalities like TENS for pain relief, electrical muscle stimulation for strengthening, and other electrical treatments used in esthetic and rehabilitative settings.
