In briefFour forms of electrical stimulation are clinically useful in the rehabilitation of injured athletes. These forms differ mainly in the way they combine the parameters of wave form, frequency, pulse width, and amplitude. Transcutaneous electrical nerve stimulation provides effective relief of both acute and chronic pain. High-voltage pulsed galvanic stimulation has several treatment indications, including pain, swelling, tissue injury, and infection. Interferential electrical stimulation is used for muscle relaxation, analgesia, and to promote soft-tissue healing. Minimal electrical noninvasive stimulation is purported to facilitate tissue healing. Electrical stimulation should be used In concert with other modalities for a complete rehabilitation program.
