This study compared two ways of treating chronic muculoskeletal pain, using randomized assignment of 131 patients to one of two electrotherapy methods: electroacupuncture or acupuncture-like TFNS. For the latter a new device called Codetron (Trademark of FHM) was used which had many features to ensure strong and unhahituated stimulation. For both methods, frequencies of 4 Hz and 200 Hz were used to optimize release of endorphins and serotonin. Initial outcomes were evaluated using visual analogue scales for pain relief and activity improvements. The “initial” outcomes during treatment weeks were not significantly different for both electrotherapy methods. Follow-up data were obtained by telephone 4 to 8 months after cessation of therapy: these were significantly better for Codetron than for eleetroaeupuncture but we must remain cautious about telephone interviews.
