Introduction
Autonomic nerve system includes sympathetic and parasympathetic divisions, which cooperatively regulate individual organs. By monitoring the activities of autonomic nerve system, abnormal organ motion can be detected. Heart Rate Variability (HRV) has been brought up to attention recently as a quantitative measurement for monitoring autonomic nervous activity. HRV can also be used to investigate the correlation between autonomic function and Chinese medical constitution.
Peripheral facial nerve palsy is a disease which clinical characteristics include the following: lower lip that fails to pull down on the normal side and the affected eyelid unable to close, giving the face an unbalanced appearance. It is also called facial nerve palsy. The disease can be found at any age of persons but mostly between 20 to 40 years old. The incidence of facial nerve palsy occurring on both sides of face is approximately equal.
In this study, HRV value was used as an indicator of autonomic nerve function to investigate the alteration before and after acupuncture therapy on adult patients with facial nerve palsy.
Method
Thirty adults aged from 20 to 40 with facial nerve palsy were selected into the experimental group in this study. Time domain and frequent domain of HRV was measured from individuals in both experimental and control group. The control group consists of thirty-three healthy adults within the same age to compare the differences. Moreover, this study will evaluate the effect of acupuncture therapy on the patients with facial nerve palsy.
Results
The low frequency-LF power (msec2) of male adults with facial nerve palsy is significantly lower than healthy male adults in the control group by Mann-Whitney Testing (p<0.05). Female adult patients with facial nerve palsy compared to healthy female adults also using Mann-Whitney Testing (p<0.05) shows a lower level on the following indicators: the proportion derived by dividing NN50 by the total number of NN interval ( NN50:the number of interval differences of successive NN intervals larger than 50ms.)-pNN50％, Total Power(msec2), low frequency-LF Power(msec2), high-frequency-HF Power(msec2). It also showed that heart rates of both male and female adults with facial nerve palsy were significantly lowered after acupuncture treatment in Wilcoxon Testing (p<0.05).
Conclusion
Heart rate variability can monitor the autonomic nerve system function. This study evaluated the autonomic nerve system activity and acupunctural therapy on adult patients with facial nerve palsy. The purpose of this study is to prove the facts of Yin-Yang balance and the balance of sympathetic and parasympathetic power spectral density of healthy males and females. In theory, that male adult patients with facial nerve palsy who has lower sympathetic power spectral density infers they are Yang vacuity constitution; that female adult patients with facial nerve palsy who has lower sympathetic and parasympathetic power spectral density infers they have Yin-Yang vacuity constitution. The above two statements correspond with recent clinical findings which can be used as an indicator and reference for treatment. As to the results of pre and post acupunctural therapy revealing a lower heart beats on adult patients with facial nerve palsy, it express acupuncture to stimulate pain and influence the heart rate excitement; it may assume that acupuncture sensation can accomdation and regulate the organ function.
