title: [Quantitative research on effects of electroacupuncture on different parameters on analgesia in rats with adjuvant-induced arthritis].
abstract: To research the effects of electroacupuncture on different quantitative parameters on analgesia in rats with adjuvant-induced arthritis. Rats of adjuvant-induced arthritis were treated by electroacupuncture with different waveforms. Pain threshold and swelling degree of joint were observed. Electroacupuncture parameters being selected were measured by frequency spectrum analysis. After treatment, the pain thresholds in the electroacupuncture groups with different waveforms were higher than that of the model group (P < 0.05, P < 0.01); the local swelling degree of inflammation of the electroacupuncture groups were higher than that of the model group (P < 0.01), but was lower than that of the control group (P < 0.05, P < 0.01). Frequency, current, voltage and pulse width of successive wave and intermittent wave were similar. Frequency,current, voltage and pulse width of sound electric wave changed continuously. The results were that all the electroacupuncture with different waveforms had the analgesic effect in rats with adjuvant-induced arthritis and the therapeutic effect of the electroacupuncture of sound electric wave was the best. It is reasonable and important that electroacupuncture parameter should be quantified.
