PENS Therapy (Percutaneous Electrical Nerve Stimulation) is an innovative technique of peripheral stimulation of the nerve endings contained in the subcutaneous tissue; this procedure aims at resolving the painful symptomatology.
PENS Therapy induces an analgesic effect in patients with pain, in restricted areas, resistant to drug therapies.
This mini-invasive technique is advised as an effective and safe treatment of various pathologies that cause chronic pain such as:
- occipital neuralgia;
- trigeminal neuralgia;
- peripheral neuropathic pain;
- cervicalgia and cervicobrachialgia;
- post-surgical scars;
- low back pain.
The procedure is performed outpatient and lasts about 25 minutes; it consists of introducing, after local anesthesia, an electrode of suitable length (2 to 20 cm) in the subcutaneous tissue of the affected area in order to intercept the trajectory of the target nerve.
Low-voltage electric pulses released by the electrode modulate nerve activity by interrupting the propagation of the pain signal to the brain (Gate control theory). Thanks to the output of an alternate frequency (between 2 and 100 Hz), the release of endogenous opiates is stimulated, with an important analgesic effect.
The effectiveness of the procedure is immediate, repeatable, well tolerated by the patient, with no side effects and validated by authoritative clinical trials and by International Medical Technology Organizations.
PENS is indicated for patients not susceptible to surgery, as a first conservative therapeutic approach or as a postoperative treatment to reduce recovery time.
