RESUMO
In this research we conducted a comparative study on the pain threshold elevation resulting from “exercise” work loads, ie. running and cycling, and acupuncture anaesthesia. 10 subjects participated throughout our research; whereas, additional subjects only participated in selected experiments. It was found that the pain threshold increased for both exercise work load and acupuncture anaesthesia; however, no significant correlation was found between the pain threshold elevation percentages resulting from exercise work load and acupuncture anaesthesia.<br>Therefore we propose, although it has been ascertained that the elevation of pain threshold involves the endomorphin mechanism, that there must be other important mechanisms involved as well.
RESUMO
A statistical study on effects of laser-puncture was carried out. In addition, an attempt was made to compare between the effect of acupuncture and this method. The treatments were under-taken for various chronic and acute cases with pain. In the laser-puncture treatment, two types of laser (<i>i, e.</i> low energy 10mW laser and 70mW sharp laser) were used. Laser-beam was given to 20-30 points which were located in painful areas, innervating nerve areas and remote areas for 40 sec for each.<br>In the open study, 10mW laser-puncture was effective (including ‘rather effective’) in 64% of the cases, and 70mW laser-puncture 73%. In the blind test, ‘the day’ evaluation showed that the laser-punctures were more effective than placebo treatment: 10mW laser-puncture was effective in 80% of the cases, and placebo in 67%. 70mW laser-puncture was effective in 87% of them, and placebo in 80%. <i>In situ</i> acupuncture was effective in 97%, and no effect was seen in 7%.<br>Only ‘the day’ evaluation in the open study showed that 70mW laser-puncture was more effective than 10mW one. In the blind best, 10mW and 70mW laser-puncture were more effective than placebo, and in situ acupuncture was more effective than the laser-punctures, but there were no significant differences among the three treatmets.
