Percutaneous Electric Nerve Stimulation (PENS) Therapy Definition

Like TENS therapy, percutaneous electric nerve stimulation (PENS) therapy uses electric currents to stimulate sensory nerves and lessen the intensity of pain. PENS therapy uses thin needles that pierce the skin and get closer to nerve endings than TENS therapy can and is sometimes recommended if TENS therapy has not been successful.

PENS therapy is likely to be used first by a doctor or health care practitioner but can also be done at home. While some people see improvements immediately, others may require multiple sessions.
