Clinical experiences of the transcutaneous afferent electrical stimulation therapy for various types of intractable pain are reported. A total of 29 pain patients included 9 residual or recurrent chronic pain patients who had had various destructive pain treatment, 15 non-malignant chronic pain patients and 5 patients with pain due to malignant tumors. In 93% of the patients complete or partial relief of pain was observed. After the subsequent successive stimulation therapy from a week to two years and ten months 86% of the 22 patients who could use the stimulator by themselves in free of charge got pain relief in more or less degree. Only 42% of these patients, however, wished to continue this therapy for their pain relief. All the malignant tumor patients and many posttraumatic chronic headache patients with Barre-Lieou syndrome discontinued electrical stimulation. Good benefits are to be expected from this non-destructive treatment for chronic pain in combination with medication and/or destructive treatment.
