- Abstract:
- Background: The main goal of this diploma thesis is the continuous and systematic examination of laser acupuncture at ear acupoints in addition to body acupoints. Laser needle acupuncture allows the optical stimulation of individualized acupoint combinations and thereby enables variations of ear and body acupuncture. Effects on cardiovascular parameters were speci?ed. Methods: 13 healthy volunteers were stimulated with a noninvasive Lasermicroneedle® system at the ear acupoint Shenmen and at the body acupoints Neiguan and Baihui. Two stages with 30 minutes each and laserstimulation with 2 Hz and 100 Hz were implemented. To quantify the biological parameters, measurements with the arteriograph were executed, the heart rate variability was measured and temperature differences were covered and subsequently statistically evaluated. Results: During the 2 Hz laser stimulation a signi?cant decrease of the heart rate could be veri?ed. The same effect occurred at the end of the period of measurement during the 100 Hz stimulation and at the end of the control phase (p<0.05). The LF (low frequency)/HF (high frequency) ratio showed a signi?cant difference during the stimulation with 2 Hz (p=0.023 and p<0.019, respectively) and a highly signi?cant difference during and after stimulation with 100 Hz (p<0.001). A signi?cant increase of the temperature at the ear acupoint Shenmen during stimulation with 100 Hz (p<0.05) occurred. The evaluation of the arteriograph data, the data of the heart rate variability and the temperature measurement showed no signi?cant results. Conclusion: Laser acupuncture with different frequencies is able to decrease the heart rate and can lead to an alteration of the LF/HF ratio. Quanti?cation technics constitute an appropriate method to display veri?able changes of the biological parameters during laser acupuncture.
