The aim of this study was to examine the effect of differences in age and sex on vestibular evoked myogenic potentials (VEMP), particularly in normal participants. Briefly, the VEMP is a response elicited by loud clicks or tone bursts recorded from the tonically contracted sternocleidomastoid muscle. A total of 72 participants were divided into 6 groups according to their age and sex (20~30/F, 20~30/M, 40~50/F, 40~50/M, ${\geq}60/F$, ${\geq}60/M$). We got the data of latency, amplitude, and asymmetry index of the amplitude(ASI) from them. As a result of this study, there are variations in VEMP amplitudes and ASI depending on the muscle tension and the intensity of stimuli. In contrast, the latency of the response is usually less varied and does not differ significantly.

This study aims to examine the effects on nociceptive neuron excitability by application of electroacupuncture in rat with inflammation. It used 20 rats for experiment, divided them into control group, electroacupuncture group (EA group), caused hyperalgesia by injecting ${\lambda}$-carrageenan into hindpaw and conducted treatment three times for experimental period. Change of NFR(reaction time, RMS) showed no significant differences among EA group showed significant differences compared to control group from 48 hours. This study showed that EA group had an effect on nociceptive neurone excitability. Therefore, it is considered that electroacupuncture for pain control will be very desirable.

This study was to compared the effectiveness of piroxicam gel phonophoresis with conventional ultrasound therapy in knee osteoarthritis. Eighteen patients with a means age of $55.7{\pm}5$ years were randomly assigned to phonophoresis or ultrasound groups. Continuous ultrasonic waves of 1 MHz frequency and $1\;W/cm^2\;SATA_i$ were applied for 5 minutes to the target knee joint. This study indicated their pain level by marking on a visual analog scale(VAS) at the start of treatment and at the end of 3day. Osteoarthritis VAS scores, pain on rest state, non weight bearing range of motion, 20 meters walking, and walking step by the patients were evaluated before and after therapy. Both therapeutic modalities were found to be effective and generally well tolerated after 3 therapy sessions. But piroxicam phonophoresis was not superior to conventional ultrasound in patients with knee osteoarthritis.

The purpose of this study was to determine the effect of transcutaneous electrical nerve stimulation(TENS) on the alteration of pressure pain threshold of myofascial trigger points. We used fifty nine patients with upper trapezius mayofascial pain syndrome. Participants classified according to each group in conventional TENS(high rate, low intensity) and acupuncture like TENS(low rate, high intensity). The test was measured continuously pre test, post-test by algometer. The following results were obtained; 1. Pressure pain threshold were significantly increased in all groups(p<.001). 2. In comparison between groups, pressure pain threshold were not significantly differenced. These results lead us to the conclusion that each method by TENS were significantly increased pressure pain threshold of upper trapezius trigger points. Therefore, a further direction of this study will be to provide more evidence that TENS method have an effect on pressure pain threshold of myofascial trigger points.

Functional Electrical Stimulation(FES) cause paralysed muscles to contract in some clinical circumstances. Generally, FES has been thought of as a valuable tool in activating any skeletal muscle paralysed as a result of upper motor neuron damage. But, the function of cardiac and smooth muscle is also affected by upper motor neuron damage. Today, various applications of FES are investigated, including conditioning cardiovascular exercise, caugh and breathing assistant, improving bowel and bladder control, hand grasp, standing and walking etc. This review will focus on the literature reporting application of FES to control respiratory capabilities and internal organ function as well as increase muscular strength, hand grasp, standing and walking in patients with upper motor diseases.

The purpose of this study was to analyze. The effect of participation physical activities on health care patterns in the aged. The subject of the study was selected by multi-stage stratified cluster random sampling among the aged center and aged club to participate program whose age were 65 and over year old among inhabitant the Kwangju metropolitan area. The data were collected through a questionnaire adapted from Payne and Hahn's(1986) 'Understanding Your Health-A personal profile; Evaluating Your Health'. The pilot test was executed after the questionnaire was translated into Korean.

To provide reflection diagnostical basic-data by ultrasonography intended for 38 male/female students used by ultrasound imaging system and dynamometer, compared the MVIC and muscle thickness take an accurate measurement of elbow flexor and knee extensor of thickness and MVIC, in confirmity with distinction of sex and then analysised of correlation in muscle thickness-MVIC, MVIC-weight, weight-muscle thickness, it shows statiscally significant difference MVIC and muscle thickness according to sex. Also there is a high interrelation between two. As well as it shows that there is a different between sex in the MVIC of same thickness and MVIC of same weight. This difference will be related with preportions of muscle fiber type in view of the results by preceded research, it needs to be prerequisite analysis of difference in sex with a great variety of ways hereafter.

Estrogens are critical to the functioning and maintenance of a diverse array of tissues and physiological systems in mammals. The actions of estrogen on such classical targets as the reproductive tract, gonads, mamary tissue, and hypothalamic/pituitary axis have been well characterized. A role in nonreproductive tissues, such as maintenance of bone mineral density and cardiovascular health in woman, as has been described. There were ne significant differences in the average of body weights, testis weights, among the experimental groups. The lumen of rate testis began to dilate from the day 8 and continued to the 59 post-treatment. The average diameter of dilate of rate testis in ICI 182,780 treated group increased 2.3-fold compared to the control group. Epithelical cell height in the rate testis of the treated mice decreased all the time periods, compared to the control.

In experimental method, this study was that galvanic vestibular stimulation in vestibular system influenced the excitability of spinal neuron through. H-reflex was measured by galvanic vestibular stimulation of binaural(right-negative pole and left-positive pole) at left head turning and prone position in sixteen normal subjects in their twenties age were selected. The summary of the comparison results were obtained below. 1. In the change of H reflex according to galvanic vestibular stimulation(GVS), Hmax amplitude(p<.05) increased significantly after stimulation. 2. In the change of H reflex according to galvanic vestibular stimulation(GVS), Hmax/Mmax ratio(p<.05) increased significantly after stimulation. In the conclusion, galvanic vestibular stimulation influenced the excitability of vestibulospinal tract and spinal neuron.
