Abstract: Objective: We examined the effects of low frequency electro-acupuncture therapy (EAT) in young women with‘Hie’symptoms, which were classified according to the presence of the vasomotor dysfunction as determined by the postural change test. Subjects and Methods: Subjects were 43 women (mean age, 21.2 years) who exhibited‘Hie’symptoms. The postural change test was performed in five-minute-loads in a standing position after a rest period of 10 minutes in a spine position. The skin temperature in the lower limbs was measured before and after the test. A stainless steel acupuncture needle (length, 40 mm; diameter, 0.2 mm) was inserted approximately 15 mm in depth at SP6 (Sanyinjiao, Saninko). EAT using an active electrode (needle) at SP6 and a reference electrode (surface electrode) at the lateral-anterior aspect of the lower leg were carried out at a frequency of 1 Hz for 20 minutes. The therapy was provided in a total of 5 sessions, with 1 session per week, and the postural change test was performed after 5 sessions. Thermal images from the medial aspect of the foot to the tibial aspect of the lower leg were captured using a thermography device, and mean skin temperature was calculated in selected regions of the toes and tibial aspect of the lower leg. Effects of the therapy were also evaluated using an original questionnaire (‘Hie’diary) concerning‘Hie’symptoms, which consists of six categorical scales of 14 symptoms including‘Hie’and severity of‘Hie’on a Visual Analogue Scale (VAS) was used. Moreover, changes in health-related quality of life by acupuncture were evaluated using the SF-8 Standard Edition. Results: Subjects were classified according to the results of the postural change test: 23 people (no vasomotor dysfunction group; non-vd group) whose skin temperature in the toe decreased after the postural change and 20 people (vasomotor dysfunction group; vd group) whose skin temperature in the toe increased after the load or showed a different reaction between right and left. In the vd group, the total score of 14 symptoms in the‘Hie’diary was significantly higher, and subjective‘Hie’symptoms showed a more severe score than that in the non-vd group. The bodily pain score in the SF-8 in vd group was significantly lower than a national reference value. After an EAT session, the vd group’s skin temperature on the tibial aspect of the lower leg at 20 minutes after completion of the load was significantly higher than that before the load. Moreover, changes in the VAS score and SF-8 score showed no statistical significant in both groups, but the total score of 14 symptoms decreased significantly in the vd group. Conclusions: We suggested that normalization in the blood vessel reaction in lower limbs by EAT at SP6 contributed to the improvement in the systemic condition that was determined by the postural test. The issue of further investigation is to elucidate the pathogenesis andor establishment of the treatment in the subjects with‘Hie’symptom whose vasomotor function was within normal limits.
