Experience with transcutaneous electrical nerve stimulation for relief of intractable pain in cancer patients

Sixty patients with intractable cancer pain were subjected to transcutaneous electrical stimulation for pain control. Evaluation, after two weeks of treatment, revealed: 17 (28.3%) excellent response, 22 (36.2%) fair and 21 (35.0%) no relief. Re-assessment after 3 months revealed 9 (15%) excellent responses, 11 (18.3%) fair and 40 (67%) failures. Extremity and trunk pains appeared to be most rewarding to patient pain, so far as pain relief is concerned. Perineal and pelvic pains were most difficult to control, only 5 of 12 (41%) cases obtained some short term relief. Pain location and sources correlated with treatment results.
