Acupuncture stimulation was performed again at the point Dazhui (GV14) located below the spinal process of the 7th cervical vertebra. As mentioned in the previously published parts of the study, this is an important point for treating common cold, occipital headache, cervical spondylosis, and torticollis. This point is also commonly used for moxibustion, and is therefore suitable for violet laser stimulation, which to some extent also produces heat effects that are described in this paper.Heart rate (Medilog AR12; Huntleigh Healthcare, Cardiff,UK) and blood pressure (Cardiocap, Datex, Hoevelaken,Netherlands) were recorded in addition to the temperature parameters (compare also [1,2]).
