Laser acupuncture - innovative basic research: visual and laser-induced evoked potentials

Abstract

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.

Laser Acupuncture: 35 Years of Successful Application in Russia (Narrative Review)

“…For example, Branco and Naeser 41 recommend to use a red laser (633 nm, 15 mW) for patients with carpal tunnel syndrome to stimulate APs nearby the skin surface, and pulsed infrared (905 nm, 9 W pulsed power) to illuminate deep-seated affected tissues and organs. There are publications in which other wavelength values were used to stimulate corporal APs: 405 nm, 36 658 nm, 42 670 nm, 43 685 nm, 36,44 830 nm, 45,46 950 nm, 47 and so on. But the parameters specified in Table 1 are most optimal.…”

Most studies in these categories were focused on phenomenological observations or consisted of a small number of clinical trials.…”
