The Basic Study of Electro-Acupuncture-Therapy by Low Frequency. (II). The Effects on Respiratory function and Heart rate by different points stimulation and different frequency stimulation / 全日本鍼灸学会雑誌

ABSTRACT

The purpose of this study was to observe the effect on the change of heart rate and respiratory function by four kinds of different stimulation. We applied low frequency stimulation (1-30Hz) to 15 healthy volunteers. Each subject received stimulation at both 1Hz and 30Hz on Hegu (LI4)/Kong zui (L6) and rhomboids muscles.<br>The results indicated that a 1Hz current injection on the rhomboids muscle was the most effective for the respiratory function. An increase in the forced vital capacity (FVC) and the forced expiratory volume in one second (FEV1), and a decrease in the peak expiratory flow (PF) were observed. The change showed a similar tendency to that of a 1Hz stimulation to the rhomboids muscles of the patients wish asthma. This results suggests that the clinical application of acupuncture stimulation is feasible for respiratory diseases.<br>We also observed a correlation between the respiratory function and the autonomic function of heart on the 30Hz stimulation using points Hegu (LI4) and Kong zui (L6).
