Litscher G - Evid Based Complement Alternat Med (2007)

Bottom Line: The assessment of acupuncture-induced effects on brain function is crucial.In this way, individual combinations of acupuncture points can be stimulated simultaneously according to traditional Chinese medicine.In the context of double-blind studies, effects in the brain could be demonstrated in a reproducible manner for the first time.

ABSTRACT
The assessment of acupuncture-induced effects on brain function is crucial. Ultrasound-assisted brain function monitoring and bioelectrical methods as well as near infrared spectroscopic procedures and functional magnetic resonance investigations form the basis for the latest scientific examination methods for acupuncture research. The laserneedle acupuncture, which was examined scientifically for the first time in Graz, represents a new painless and non-invasive acupuncture method. In this way, individual combinations of acupuncture points can be stimulated simultaneously according to traditional Chinese medicine. In the context of double-blind studies, effects in the brain could be demonstrated in a reproducible manner for the first time. This second part of the short review article summarizes some of the centrally measured effects of acupuncture obtained at the Medical University of Graz within the last 10 years.

This diagram shows stimulus intensity as a function of time. On the left, the hypotheses and on the right side real measured cerebral responses of NIRS parameters and bioelectric responses are shown. Note the difference between the metal needle and laserneedle. Metal needle shows a short-term increase and laserneedle a continuous increase like a plateau. Modified from (28,29).

Figure 6: This diagram shows stimulus intensity as a function of time. On the left, the hypotheses and on the right side real measured cerebral responses of NIRS parameters and bioelectric responses are shown. Note the difference between the metal needle and laserneedle. Metal needle shows a short-term increase and laserneedle a continuous increase like a plateau. Modified from (28,29).

Mentions: Figure 6 shows the hypothetically supposed function curves of stimulus intensity dependent upon the supposed duration of treatment. This diagram gains in value due to the actually measured, specific cerebral data regarding the changes in O2Hb and HHb shown on the right. The trend of the O2Hb parameter monitored by NIRS during laserneedle stimulation is nearly plateau-like. During manual metal needle stimulation, however, the O2Hb curve shows a sharp increase and a sharp decrease back to a value higher than the initial level.This is also the case in other parameters [e.g. bispectral analysis (BIS) of the electroencephalogram (EEG)] (6,7,28).Figure 6.
