This study was carried out (a) to investigate the variations of blood chemistry and (b) to examine the secretion trend of endocrine substances in a dog model after electroacupuncture and laser stimulation at different time period(9 to 11a.m. and 6 to 8p.m.). Two acupuncture points ; Da Zhui(GV-14) and Shen Shu(BL-23) were electroacupunctured for 20 minutes with 2Vol, 20Hz and irradiated for 5 minutes with 8,000Hz. Before stimulation and after a lapse of time(10-minutes, 30-minutes and 60-minutes) all dogs were checked the following parameters ; cortisol, ACTH, RBC, hemoglobin, hematocrit, WBC, Ca, P, SGPT, SGOT and creatinine. The results were as follow : The levels of cortisol and ACTH have been increased 10 minutes after the stimulation of the electroacupuncture and laser. The higher levels of cortisol and ACTH have been decreased to keep the normal levels from 30 minutes after the stimulation of the electroacupuncture and laser. The RBC, hemoglobin, hematocrit and WBC showed the physiological phenomena in the electroacupuncture and laser stimulation. In sero chemical analysis, calcium, phosphate, SGOT, SGPT and creatinine levels were within normal physiological ranges.

Objectives : This study is to investigate stimulation effects of acupoints at differential meridian along arm and leg on the physiological phenomenon of heartbeats. Methods : 8 subjects were participated in this study. The experiments were performed in Resting session(Rs), Insertion session(Is), Stimulation session1(Ss1), Stimulation session2(Ss2), Stimulation session3(Ss3) sequence. Time of each session and the interval between each session was 30 seconds all. Acupuncture was performed manually on PC3 or LR8 at random with a two-day interval. stand deviation of N-N interval(SDNN) was measured for each session. Results : At PC3, SDNN increased in Ss1, Ss2, and Ss3 compared to Rs but at LR8, there was little change between Ss1, Ss2, Ss3 and Rs. Post-hoc analysis revealed that mean value of SDNN significantly increased in Ss1 compared with Baseline at PC3, while there was little change at LR8. When LR8 and PC3 were compared at each time point, there was a significant difference only in Ss1. Conclusions : Our results indicate that there is a correlation between specific physiological functions and acupoints.

The purpose of this study was to examine the effects of neuromuscular electrical stimulation(NMES) on the spasticity of elbow flexor. Ten spastic hemiplegia who have been at EUL-JI medical college hospital in Taejon with age range of 35 to 70 years$(56.8\pm9.5)$, were participated in this study. The subjects (5male, 5female) took neuromuscular electrical stimulation therapy on the triceps of the affected elbow. To compare the effect of the treatment, the grade of spasticity of affected elbow flexor was measured at pre-treatment and the end of each weeks using modified Ashworth scale. Then, the range of extension of the affected elbow was measured at pre-treatmen and the end of each weeks using full circle goniometer. The data were analyzed with ANOVA to determine significant differences with the passage of time. The results were as follows: 1. ANOVA test showed significant differences in reducing spasticity of NMES group with the passage of time (p<.01). 2. ANOVA test showed significant differences in increasing range of motion with the passage of time of NMES group(p<.01). The neuromuscular electrical stimulation is a effective method to reduce the spasticity of elbow flexor.

A mechanical or electrical stimulation to the mandibular symphysis during a maximal voluntary clenching of the teeth always produces a jaw jerk followed by a silent period (transient stops) in the masseteric EMG (electromyogram). Generally, a mechanical stimulation is followed by a single silent period, and an electrical stimulation is followed by multiple silent periods. In this paper, we propose a new algorithm for determining the duration of the masseter silent period. The decision approach in essentially based upon a segmentation algorithm consisted of variance filter, median filter and gaussian filter. The new adaptive digital notch filter using R-CLMS(reverse constrained least mean-squared) algorithm is proposed for the elimination of powerline(60Hz) noise. At the same time, we design a real time measurement system for the EMG silent period under Window base.

This study was performed to investigate the effects of urinary acupoint (BL-23, BL-28) by acupuncture (AP) and electroacupuncture (EA) on urinary bladder in dogs. Four healthy male dogs aged within the range of 6~8 months were used in this experiment. For Electrodes implantation on the bladder, dogs were to undergo surgical operation. The purpose of investigating the effect on urinary bladder was to evaluate electromyogram (EMG) changes according to AP or EA at Shen Shu (BL-23), Pang Guang Shu (BL-28) and non-acupoint. AP and EA (2~4 V, 10 Hz) were applied for 20 min to each point. EMG was evaluated when acupuncture began stimulation and as soon as the stimulation by electroacupuncture was gone. By the experiment of investigating the effect of urinary time it was estimated to measure time up to urination from stimulation on effective acupoint, after saline was filled with 70% of whole volumes on urinary bladder. The wave of EMG on resting stage showed simple and regular, whereas that of EMG on urination showed irregularly strong peaks before urination. Acupuncture of BL-28 had an influence on changes of EMG which had irregular peaks on urination. But the changes of EMG after acupuncture of BL-28 and control were regular like resting stage. The changes of EMG after EA at BL-23 and BL-28 showed irregularly a variety of wave forms. The interval through urination from stimulation at BL-28 and control become short as measuring time by EA (p<0.01). According to the results, AP at BL-28 was effective to urinary bladder. EA at BL-23 and BL-28 was effective to urinary bladder. Especially, the interval on stimulating at BL-28 by EA was the shortest in measuring time to urination from stimulation.

Purpose : This study aims to examine the influences of galvanic vestibular stimulation on autonomic reaction of normal adults. Methods : Participants in this research totaled 28 (14 men and 14 women). Galvanic vestibular stimulation was conducted with a binaural electrode configuration for 60 sec. Galvanic vestibular stimulation measurements were conducted with the subjects in a prone position. Measured items included skin conductance, blood flow, pulse rate, and respiratory rate. Measurements were repeated for a total of five times, before application, during application, after application, 5 minutes after application and 10 minutes after application. Results : Skin conductance reaction showed statistically significant differences in changes depending on time after galvanic vestibular stimulation and there were statistically differences in changes of blood flow, pulse rate and respiratory rate after galvanic vestibular stimulation. Conclusion : Blood flow, pulse rate and respiratory rate of autonomic reactions were not influenced by galvanic vestibular stimulation, but skin conductance reaction was influenced by it and it was found that it was reduced during and after stimulation rather than before stimulation. Consequently, it was considered that galvanic vestibular stimulation affected the autonomic reaction.

Purpose: This study was conducted to determine how stimulation using Russian current changes isokinetic exercise performance of quadriceps muscle and its antagonist muscles. Methods: Subjects were 20 20-year-old healthy adults who were instructed in the flexion to extension of knees in angular velocity $60^{\circ}/sec$ and $180^{\circ}/sec$ using a Biodex (Biodex system 3). We measured the difference in muscle performance between the Russian current stimulated at the same time during the flexion to extension of knees and not stimulated. Results: The results showed that when Russian current stimulation was applied at the angular velocity $60^{\circ}/sec$, the flexed and extended muscles and the angular velocity $180^{\circ}/sec$ increased significantly, but the peak torque of flexing muscles at the angular velocity $180^{\circ}/sec$ did not increase. Conclusion: These findings suggest that Russian current stimulation with isokinetic exercise of the knee joint could affect the quadriceps muscle and its antagonist muscle performance of muscle strength and endurance.

The purpose of this study was to determine whether percutaneous interferential current stimulation on thoracic sympathetic ganglia with amplitude modulated frequency (AMF) $90\~100$ bps and subthreshold of muscle contraction for 10 minutes on peripheral blood flow velocity in healthy subjects. Thirty-seven healthy volunteers were assigned randomly into an experimental group (n=25) and a control group (n=12). the experimental group received interferential current stimulation with subthreshold of the muscle contraction of current at AMF $90\~100$ bps on $1st\~5th$ thoracic sympathetic ganglial region for 10 minutes. The control group received same handling and electode placement, but no current was applied. Using a Doppler blood flow meter, the radial arterial blood flow velocities and the pulse raters were determined for two-way analysis of variance for repeated measures on time and group. There were no significant difference between the two groups with respect to the changes in arterial blood flow velocity and pulse rate over the four measurement times. Interferential current stimulation did not change in mean blood flow velocity and pulse rate. We conclude that interferential current stimulation on the thoracic sympathetic ganglia, as used in this study, did not dilate peripheral artery. This results suggests that interferential current stimulation dose not alter the activtiy of sympathetic nerve.

Purpose To investigate the difference of total activation in visual area, motor area, and cerebellum according to the stimulation paradigm. Materials and Methods Functional MR imaging was performed in 5 healthy volunteers with visual and motor activity using EPI technique. LED and Checker-Board stimulation were performed for visual activity. Thumb motion and Finger tapping were performed for motor and cerebellum activity. Time course data was obtained by calculating the total activation which was defined as the number of activated pixels x averaged pixel intensity. Results In the case of visual activity with LED stimulation, we found increased total activity of more than 100% compared with Checker-Board stimulation. In the case of motor area and cerebellum with Finger tapping stimulation, we found increased total activity of more than 100% and 150%, respectively compared with Thumb motion stimulation.
