Electrotherapy is a treatment technique that uses electrical currents to stimulate nerves and muscles to alleviate pain, reduce inflammation, and improve muscle function. Common electrotherapy modalities include TENS (transcutaneous electrical nerve stimulation), EMS (electrical muscle stimulation), and IFC (interferential current). Electrotherapy is often used in conjunction with other rehabilitation treatments, such as manual therapy or therapeutic exercise, to provide comprehensive care.

By applying electrical stimulation to the affected areas, electrotherapy can help to reduce pain, increase blood flow, promote tissue healing, and strengthen weakened muscles. It is commonly used for conditions such as chronic pain, muscle spasms, arthritis, and post-surgery recovery.

Electrotherapy is non-invasive, relatively painless, and an effective modality for improving functional recovery in both acute and chronic conditions.
