Integrative laser medicine and high-tech acupuncture at the medical university of graz, austria, europe

At the moment, modernization of acupuncture has a high priority. On the traditional side, acupuncture has only recently been awarded the status of Intangible Cultural Heritage by the UNESCO. On the innovative side, high-tech acupuncture is a registered trademark in Austria. Acupuncture has been used for medical treatment for thousands of years. A large number of empirical data are available but the technical quantification of effects was not possible up to now. Using electroacupuncture, needle, or laser stimulation and modern biomedical techniques, it was possible for the first time to quantify changes in biological activities caused by acupuncture. This paper which serves as introduction for the special issue “High-Tech Acupuncture and Integrative Laser Medicine” of the present journal, focuses on the latest innovative aspects that underline the further enhancement and development of acupuncture. Special emphasis is given to new methodological and technical investigations, for example, results obtained from all kinds of acupuncture innovations (e.g., teleacupuncture) and integrative laser medicine.

Quantitative Bestimmung geschlechtsspezifischer thermischer Empfindungs- und Schmerzschwellen vor und nach Lasernadelstimulation / Quantification of Gender Specific Thermal Sensory and Pain Threshold Before and After Laserneedle Stimulation

Quantitative thermal sensory and pain threshold testing (QST) was performed in 29 adult healthy volunteers (mean age 24.2 +/- 2.7 years; range: 18-29 years; 20 females, 9 males) using the Thermal Sensory Analyser TSA-II (Medoc Advanced Medical Systems, Ramat Yishai, Israel, and Minneapolis, Minnesota, USA) before and after laser needle acupuncture and placebo stimulation, respectively. Significant (p < or = 0,001; t-test) gender-specific differences were seen on cold pain threshold analysis. No significant changes in parameters of thermal sensory and pain thresholds were found before and after laser needle or placebo stimulation at acupuncture points for acute pain. However, a trend towards change in the median value of cold pain sensation after laser needle stimulation (p = 0.479; paired t-test; n.s.) was seen within the group of healthy females. The influence of stimulation of acupuncture points for chronic pain on the various parameters needs to be clarified in future studies.

Cerebral and peripheral effects of laser needle-stimulation

This study comprises scientific-theoretic fundamental investigations of laserneedle technology, a new and painless method of acupuncture stimulation. Laserneedles are not inserted in the skin, but are merely placed on the surface of the acupuncture point. The study documents the significant changes in peripheral microcirculation (p = 0.005) and surface temperature of the skin (p = 0.02) induced by laser, in 22 healthy volunteers (mean age 24.4 +/- 2.6 years). In addition, a randomised cross-over study to characterise the specific changes in cerebral blood flow velocity with laserneedle acupuncture (p < 0.001) is presented. These results provide important information for characterising the effects of laserneedle acupuncture.
