Electrical modalities, such as neuromuscular electrical stimulation (NMES), ultrasound, transcutaneous electrical nerve stimulation (TENS), and interferential current (IFC) are all designed to stimulate tissue healing and to restore normal tissue function.

Electrotherapeutic modalities may also help with reduced dependence on pain medication.

These modalities help to manage acute and chronic pain by transmitting sound waves or electrical energy to cause neuromodulation and thereby reducing pain, swelling and inflammation, improve muscle flexibility and strength.
