Abstract
Background: Indirect moxibustion (IM) has been previously performed between the spinous process while recording skin temperature of the trunk. However, moxibustion is often applied not only to acupuncture points on the back, but also to points located on the limbs. Thus, there is a need to investigate skin temperature (ST) responses following IM applied to the limbs. Methods: In Experiment 1 (Exp 1), subjects were randomly assigned to three groups: the left IM stimulation, right IM stimulation and control groups. In Experiment 2 (Exp 2), the subjects underwent two experimental sessions consisting of a single stimulation of IM or triple stimulations of IM. The IM stimulation was administered to the ST36 acupuncture point. A thermograph was used to obtain the ST on the lower limbs. Results: In Exp 1, the ST of the lower limbs increased in the stimulation groups whereas there was no increase in the non-stimulation group. In Exp 2, no significant response occurred between the single and triple stimulation of IM groups for all observed sites except for the left ankle ST. Conclusions: Lower limb ST increased following IM application to the ST36 point. No difference was observed between the dosage of the stimulation and ST responses.
Highlights
Moxibustion is a form of thermal therapy that involves burning the herb moxa (Artemisia princeps, commonly called Japanese mugwort) over acupuncture points
For skin temperature changes in the left and right lower legs, ankles, proximal feet, and distal feet regions, no significant interactions occurred between the left Indirect moxibustion (IM), right IM, and control groups (φ = 10, f = 0.265–0.541, p > 0.85)
The skin temperature of the stimulated side of the leg increased after the triple stimulation of Previously, we reported that no differences were manifested in the temperature curves and maximum temperatures with the use of single and triple applications of IM [1]
