Objective:
To evaluate the use of a novel nonpharmacologic analgesic therapy known as percutaneous electrical nerve stimulation (PENS) in the management of opioid-resistant cancer pain.
Design:
PENS therapy was administered to three cancer patients on three or more occasion using acupuncturelike needle probes that were stimulated for 30 minutes at frequencies of 4-100 Hz.
Results:
Two of the three patients achieved good to excellent pain relief that lasted 24-72 hours after each treatment session.
Conclusion:
PENS therapy is a useful supplement to opioid analgesics for the management of pain secondary to bony metastasis in terminal cancer patients.
