The purpose of this study was to determine the effect of muscle fatigue by neuromuscular electrical stimulation(NMES). Using Biodex System 3PRO(Biodex Medical Systems Inc, USA), experiment was conducted as to the normal group(I) composed of fifteen adults and the patient group(II) composed of fifteen patients with spastic hemiplegia. As to each group, maximal tolerated intensity(MTI) and maximal tolerated isometric contraction(MTIC) in electric currents yielded by low rate(20 pps) and high rate(100 pps) neuromuscular electrical stimulation and the aspects of decrease and restoration of the isometric contraction were examined, and their strength decrement index(SDI) and strength recovery index(SRI) were also calculated. 1. As for MTI in NMES, the MTI of the group II was higher than that of the group I in both low rate and high rate NMES. In comparison within group, MTI of group II was significantly higher in high rate NMES rather than in low rate NMES(p<0.05). 2. In comparison of MTIC between groups, the group I showed higher in both low rate and high rate NMES. In comparison within group, MTIC of group II was significantly higher in high rate NMES rather than in low rate NMES(p<0.01). 3. As for SDI, both groups showed highest SDI in high rate NMES, but no significant differences could be observed. 4. As for SRI, both groups showed significantly low SRI in low rate NMES(p<0.01, p<0.05), and comparison between groups showed no significant differences could be observed. These result lead us to the conclusion that muscle fatigue was influenced by frequency, high rate NMES was lower at SDI and higher at SRI on compare to low rate NMES, therefor, a further studies concerning electrical stimulation should consider differences each frequency in response to treatment.

This study aimed at examining the effects of percutaneous electrical nerve stimulation(PENS) applied to different parts of the streptozotocin(STZ) induced diabetic rats on the change of glucose level and spinal neuron excitability. A total of twenty-eight SD rats, divided into four groups, were used as experiment animal. Experiment group I, the normal control group, was composed of normal rats without diabetes induction. Experiment group was composed II of the rats without any treatment after experimental diabetes induction. Experiment group III was composed of the rats with 2 Hz and $200\;{\mu}s$ of PENS to the acupuncture points related with diabetes for 20 minutes after diabetes induction. Experiment group IV was composed of the rats with 2 Hz and $200\;{\mu}s$ of PENS to the parts unrelated with diabetes for 20 minutes after diabetes induction. The results can be summarized as follow: As for glucose level, the group I showed no change within normal range, and the group III showed significant increase, compared with other groups (p<0.05). As for the change of H latency, M and H amplitude, the group III showed significant differences in decrease of latency and amplitude (p<0.05). As for Hmax/Mmax ratio, the normal and other groups showed no significant differences in decrease of amplitude. It can be concluded from the above results that PENS to the acupuncture points of the STZ-induced diabetic rats was effective for spinal neurone excitability, in particular, for those of the group with PENS to the acupuncture points. This study was conducted in the period of acute diabetes induction, and therefore, further study should be conducted in the period of chronic diabetes to research both acute and chronic diabetes.

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.

The purpose of this study were to examine the effect of high intensity, low frequency transcutaneous electrical nerve stimulation at auricular acupuncture points on experimental pain threshold measured at the wrist and to determine the changes in effect over time. Forty-two healthy adult men and women were assigned randomly to one of three treatment groups. Group 1(n=15) received TENS to appropriate auricular points for wrist, Group 2(n=12) received TENS to wrist, and Group 3(n=15) received no TENS. We measured experimental pain threshold at the wrist after an electrical stimulus during one pre-treatment and three post-treatment time periods. Group 1 and 2 showed stastically significant increase(p<0.05) in pain threshold after treatment whereas the Group 3 did not. Group 1 showed a significant increase in pain threshold than Group 2. These results suggest that high intensity, low frequency TENS applied to appropriate auricular acupuncture points can increase pain threshold.

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.

This research tries to find out the methods to enhance the rehabilitation ability of Cerebro Vascular Accident(CVA) patients and their family members. For this purpose, the authors identify the factors that may affect the medical rehabilitation process as well as the rehabilitation itself. Furthermore, the current status of the rehabilitation ability and the desires of CVA patients and their family members are surveyed in this research. The results of this research are as follows: Firstly, the surveyed CVA patients, most of whom are over fifties in the age, have cerebral infection and hemorrhage in a numerical order. The survey showed that the larger cities they live in, the more CVA occur to them. Secondly, the survey for the treatment cost demonstrated that the lower are their living level and their education level, the more pressure is put on the CVA patients and their family. The statistical data proved this conclusion is reasonable. Thirdly, as for the safisfaction for the rehabilitation treatment, the statistical survey showed that it is directly proportional to their financial income. Moreover, those who have lower income generally want the rehabilitation services from a public health center. On the other hand, those who have higher income want the home therapy services.
