decisive importance for the therapeutic efficiency of
acupuncture treatments. Using placebo-needles in
comparison with metal needles, it was found that the
efficiency of acupuncture treatments decreases
significantly, if placebo needles were used.
Our studies show that the new high optical
stimulation with laserneedles can elicit reproducible
cerebral effects which are in the same order (half
dimension) with respect to the maximum amplitude of
the mean blood flow velocity as compared to needle
acupuncture [1].
Conclusions
The new laserneedle system is able to induce specific,
marked alterations in cerebral blood flow velocity
of the PCA after stimulation of vision-related acupoints
on the foot and hand. At the same time blood flow velocity
in the MCA did show minor changes. Further
studies using different laser stimulus intensities and
wavelengths are in progress.
