Electrical stimulation in the relief of pain: a pilot study

A group of 26 patients who suffered from chronic pain resistant to other therapeutic measures, were given electrical stimulation in two forms. The first utilised penetrating acupuncture needles connected to a standard Chinese electrical impulse generator and the second method employed American transcutaneous stimulators with conducting skin electrodes. At long term follow-up 50 percent of patients treated exhibited sustained relief--20 percent when the device was used alone and a further 30 percent when it was combined with other forms of specific pain therapy. There was no difference in the response to needle acupuncture or transcutaneous stimulation. The best response was seen in patients with neuralgic disorders and painful musculo skeletal syndromes affecting the cervico thoracic region.
