“…4,5) All volunteers also received active laser stimulation at a placebo point (located lateral from the radius, 6 cun above the horizontal fold of the wrist exactly on the radial ledge, lateral from the pulmonary meridian; Fig. 3d) 6) , which makes this a controlled study.…”

Background and aims:The yellow laser constitutes a totally new option in the field of laser acupuncture, in addition to the already existing red, near infrared, green and violet lasers. Especially for so called lifestyle-related diseases, this could open up new methods of integrative therapy. The goal of the present study was to investigate among other parameters blood pressure (BP), heart rate (HR), heart rate variability (HRV), and temperature effects before, during, and after stimulation of different acupoints with yellow laser. Subjects and methods: We recruited 26 healthy volunteers (13 female, 13 male; mean age ± SD 24.1 ± 3.3 years) at the Medical University of Graz. The acupoints Baihui, Neiguan, Taichong and a placebo point were stimulated with a 589 nm (50 mW, 500 µm; 5 min) yellow laser. Blood pressure was measured noninvasively at the wrist; for the registration of the electrocardiogram a medilog AR12 HRV system was used. Effects on temperature were measured with a Flir i7 infrared camera. Results: There were significant decreases after yellow laser acupuncture in the systolic BP, diastolic BP also decreased (n.s.). HRV in both (men and women) increased. The temperature during the yellow laser stimulation decreased significantly in all measured points. After the stimulation it increased again significantly. Based on a questionnaire volunteers reported a significantly decreased level of stress after yellow laser stimulation. Conclusion: Significant positive effects on BP and well-being were found after yellow laser stimulation. The results are very promising and can be very important especially for the treatment of lifestyle related diseases.

“…6) Laser needle stimulation (Laserneedle GmbH, Berlin, Germany) allows the continuous stimulation of one or more acupuncture points on the body, the head, hands or ears. [8,[20][21][22][23][24][25][26][27][28][29][30][31] In the second part of this investigation, laser irradiation of 658 nm and 55 mW laser diodes was coupled into an optical fiber and the laser needle was arranged at the distal end of this fiber. Due to coupling losses, the output power of the laser needles was reduced to 40 mW.…”

“…The method is described in detail in previous publications. 8,[20][21][22][23][24][25][26][27][28][29][30][31] In order to have the laser pulses act as the sole stimulus to the average with the EEG recording system, each flash of the laser was accompanied by a 5 V pulse signal that triggered the average.…”

Background and aims:Laser acupuncture is a therapeutic medical method. Innovative basic research is necessary within this fascinating area of research. This publication focuses on visual evoked potentials (VEP) elucidated by non-invasive and partially non-perceptible laser stimulation. Materials (Subjects) and Methods: The first part of this study presents systematic VEP-monitoring in connection with laser acupuncture and manual needle acupuncture in 40 healthy volunteers. The second part deals with bilateral non-perceptible laser needle (658 nm, 40 mW, 500 µm, 1 Hz) irradiation of the Neiguan acupoint (PC6) in a 26-year-old female healthy volunteer using a new 32-channel evoked potential analysis technique. Results: We were not able to find significant changes in latency or amplitudes of VEPs during laser acupuncture within the first part of the study. However in the second part we report about human cerebral evoked potentials after non-perceptible laser stimulation. Conclusions:The findings indicate that exposure to laser needle stimulation with a frequency of 1 Hz can modulate the ascending reticular activating system. Further studies are necessary to confirm or refute the very interesting findings.

“…In this technique, a laser needle is rather fixed onto the skin than pricked into the skin, to deliver the laser power to the acupoints, and the precise power intensity can determined by using the intensity curve (Litscher & Schikora, 2002). In this way, the patient can hardly feel the stimulation and the operator may also be unaware of whether the laser needle system is active, and therefore true doubleblind studies in acupuncture research can be performed.…”
