Objectives : This study was performed in order to investigate the effectiveness of electromyography and the Heart Rate Variability(HRV) test as prognosis factors, and to clarify correlation between Electromyography and the Heart Rate Variability test. Methods : 44 Bell's palsy patients who were graded V on the House-Brackmann scale and underwent HRV and EMG testing were retrospectively reviewed based on medical records. Results from both tests were analyzed via simple linear regression, and bivariate correlation analysis was performed to investigate the correlation between results from the two tests. The severity of the facial palsy at onset and at 2 weeks after treatment were evaluated with the H-B grade and Yanagihara grading system, and was converted into improvement scores. Results : Mean axonal loss according to electromyography showed a statistically significant correlation in predicting peripheral facial palsy improvement(p<0.01). HR, SDNN, TP, LF, HF, VLF, and LF/HF ratio on the Heart Rate Variability test showed no significant correlation in predicting peripheral facial palsy improvement. Mean axonal loss determined by electromyography, and HR, SDNN, TP, LF, HF, VLF, and LF/HF ratio recorded with the Heart Rate Variability test was analyzed with the bivariate correlation analysis method. Mean axonal loss and SDNN showed a statistically significant correlation(p<0.01) Conclusions : The Heart Rate Variability test has no statistical significance in predicting peripheral facial palsy improvement. SDNN has a statistically significant correlation with mean axonal loss as determined by electromyography.

PURPOSE: The purpose of this study was to investigate the effects of ten minutes of manual passive exercise performed by physical therapists on autonomic nervous system. METHODS: Thirty-five healthy adults, both male and female, were chosen as subjects for this study. The autonomic nervous system was measured by heart rate variability (HRV),before and after passive exercise using the following measurements: mean heart rate (mean HRT), low frequency (LF) and high frequency (HF) components, the LF/HF ratio, root mean square of the successive differences (RMSSD), and the HRV index. The exercise was performed on the subjects by a physical therapist with seven years of experience specializing in the nervous system. The exercise was conducted at the mid-range of motion on the upper and lower limbs of the subjects for two minutes and thirty seconds and for a total of ten minutes. RESULTS: There was a significant increase in the LF component. The mean HRT and the LF/HF ratio both increased, but these increases were not significant. The HF component, RMSSD, and HRV index all decreased, but these decreases were not significant. CONCLUSION: In conclusion, mid-range manual passive exercise does not induce stress on the autonomic nervous system. It can safely be performed by a physical therapist.

수면단계는 수면감을 평가하는 데 있어서 중요한 생리지표로서 사용되어 왔다. 그러나 수면다원검사를 이용한 전통적 수면단계 분류방법은 뇌전도(electroencephalogram : EEG), 안전도(electrooculogram : EOG), 심전도(electrocardiogram : ECG), 근전도(electromyogram : EMG) 등을 종합적으로 측정하므로 수면단계를 비교적 정확히 분류할 수 있지만 피험자에게 심한 구속감을 주는 문제가 있다. 본 연구에서는, 각성상태에서 교감신경계가 지배적인 반면에 수면 중에는 부교감 신경계가 더 활동적인 점에 착안하여 수면단계를 간단히 분류할 수 있는 방법을 찾고자 수면단계에 따른 심박동변이도(heart rate variability : HRY)를 분석하였다. 이 실험에는 건강한 대학생 6명이 2일씩 전체 12회의 야간수면에 참여하였다. 수면다원검사 장치를 이용하여 피험자들이 수면을 취하고 있는 동안, EEG, EOG, ECG, EMG(턱 및 다리)를 측정하여 수면단계를 "Standard scoring system for sleep stage"에 따라 자동으로 분류하였다. 그런 뒤, 본 연구를 통하여 제작된 Sleep Data Acquisition/Analysis 시스템을 이용하여 수면다원검사 장치로부터 ECG신호만 추출하여 HRV의 전력스펙트럼을 3개의 영역[저주파수대역(low frequency : LF), 중간주파수대역(medium frequency : MF), 고주파수대역(high frequency : HF)]으로 나누어 분석하였다. 단일채널 ECG를 이용하여 수면단계별로 HRV의 LF/HF를 분석한 결과, W(wakefulness)단계가 2단계에 비하여 325%높게(p＜.05), 3단계에 비하여 628%높게(p＜.001), 4단계에 비하여 800%높게(p＜.001) 나타났으며, 4단계는 REM(rapid eye movement)단계에 비하여 427% 낮게(p＜.05), 1단계에 비하여 418% 낮게(p＜.05) 나타났다. 또한 LF/HF가 수면단계에 따라 변화하는 양상은 W, REM, 1, 2, 3, 4단계의 순으로 단조 감소하였다. 한편, 수면단계별 MF/(LF+HF)의 차이는 유의하지 않았으나 표본집단의 기술통계치를 살펴본 바 REM단계와 3단계의 평균치가 가장 높았다.치가 가장 높았다.

Objectives : To assess the characteristics of electropyography(EMG) and heart rate variability(HRV) values in idiopathic facial palsy inpatients of different Sasang constitutions. Methods : Medical records of 103 idiopathic facial palsy inpatients who underwent facial EMG testing and HRV testing were retrospectively reviewed. All subjects had been consulted to the department of Sasang constitution for constitution differentiation. The Sasang constitutional and age distribution were initially analyzed, and axonal loss percentage values on EMG were correlated with Sasang constitution and sex. HRV results were also correlated with Sasang constitution and sex. Results : 1. 24.4 percent of idiopathic facial palsy inpatients were of the Soyang constitution, 52.4 percent were of the Taeum, and 23.3 percent were of the Soeum. Patients in their fifties were most common in all constitutions(27.8%). 2. Mean axonal loss values for the temporal, zygomatic, and buccal branches were all statistically significantly lower in the Taeum constitution compared with Soyang or Soeum(p<0.05). 3. Mean axonal loss values for the temporal, zygomatic, and buccal branches were all statistically significantly lower in men than women(p<0.05). 4. The mean LF/HF ratio was significantly lower in idiopathic facial palsy inpatients of the Soeum constitution compared with Soyang and Taeum(p<0.05), but there was no statistically significant difference in mean MHRT, SDNN, TP, VLF, LF, and HF of different constitutions. 5. The mean SDNN was significantly lower in women inpatients compared with men(p<0.05), but there was no statistically significant difference in mean MHRT, TP, VLF, LF, HF, and LF/HF ratio. Conclusions : The Sasang constitutional composition of idiopathic facial palsy inpatients closely adheres to the composition proposed in Dong-eui-su-se-bo-won, but the Taeum and Soeum proportion is slightly larger and the Soyang proportion slightly smaller. Axonal loss value on EMG was significantly lower in the Taeum constitution, and in men(p<0.05, <0.05). Mean LF/HF ratio was significantly lower in the Soeum constitution compared with Soyang and Taeum(p<0.05), and mean SDNN was significantly lower in women(p<0.05).
