Purpose : The purpose of this study is to assess the effect for gait, balance, and depression for stroke patients by group task-related program training based motor learning theory. Methods : The subjects of this study were administrated to the 11 stroke patients (9 male, 2 female) by 5 weeks, 3 times per week, 15 times. The group task-related program training were performed gait, balance, treadmill, muscle strengthening, and game program. Each program took 7~10 minutes and total time took 60 minutes including moving time. The difference of program training were compared using the paired t-test. Results : The results of this study revealed that Fugl-Meyer motor assessment, Chedoke-McMaster Stroke assessment of lower extremity and Berg balance scale were significantly correlated. However, impairment item of Chedoke-McMaster Stroke assessment, spatio-temporal gait parameters, Timed up and go test, and depression item of Minnesota Multiphasic Personality Inventory were not significantly correlated. Conclusion : These results support that group task-related program could be a useful treatment to improve the balance skills and motor function of lower extremity for the chronic stroke patients.

Background and Objectives : The Motor evoked potentials (MEP) study may be useful in the evaluation of the degree of impairment in the motor nervous system and in the determination of the prognosis. The purpose of this study is to evaluate the status of central nervous system in acute and subacute state of cerebral ischemia by comparing the changes of MEP in the initial and follow-up study. Methods : Twenty patients with hemiparesis caused by ischemic stroke were recruited for this study. We tested MEP within 7 days and followed-up after 14 days after symptom onset. The cerebral motor cortex area, cervical area for upper extremity and lumbar area for lower extremity were stimulated by transmagnetic stimulator. The central motor conduction time(CMCT) was measured with the difference in MEP caused by stimulating the vertical area and spinal area. The CMCT of hemiparetic patients were classified into three groups-normal, delayed, and no evoked MEP groups. Results : The CMCT in hemiparetic side of acute ischemic stroke patients were singnificantly delayed (P < 0.05) compared with the control group. The CMCT of hemiparetic side in the follow-up study showed no sinificantly difference in comparison to the control group. The prognosis of motor improvement was better in the groups of delayed MEP than the groups of no evoked MEP. Conclusion : The CMCT of hemiparetic and contralateral sides were delayed in acute ischemic stroke, compared with control group and were returned to normal boundaries in subacute state. But in the most cases with no MEP response in the initial study, also showed no MEP response in the follow-up study. The recovery occurred in the subacute state in cases with mild hemiparesis, whereas recovery did not occur in the subacute stage in case with severe hemiparesis.

Background & Purpose : The purpose of this study is to evaluate the impairment of SVMC(selective voluntary motor control) of the lower extremity by assessing each joints of lower limb and to analyze the motional relationship between each joints of lower limb using SCALE(Selective Control Assessment of the Lower Extremity) during the swing phase of gait cycle in children with spastic diplegia. Method : 11 children with spastic diplegia CP who could walk independently and 10 normal developing children were participated. SCALE(Selective Control Assessment of the Lower Extremity) assessments were conducted for 11 children with CP. Gait analysis were accomplished in all participants. Qualisys motion analysis was used as a statistical tool to assess the motional relationship between hip joint, knee joint and ankle joint in each limb. We used descriptive statistics, cross-tabulation, independent t-test, linear regression to analysis motional relationship between each joints of lower limb using by SPSS ver.17.0. Result : Firstly, there were significant differences in SCALE scores between the cerebal palsy group and the control group in knee joint(p<0.05), but no significant difference in hip and ankle joints during the swing phase of gait cycle. Secondly, the difference of SCALE scores showed no statistical motional difference in knee and ankle joints during the swing phase, and showed significant motional difference in hip joints during the swing phase(p<0.05). Thirdly, there was a liner relationship between the motion of hip and ankle joints during the swing phase. Conclusion : The nature of SVMC(selective voluntary motor control) in each joints of the lower limb may reflect the ability of gait, thus SCALE may be used for assessing and for treating the cerebal palsy patients who are able to walk independently. Also we knew that the impairment of SVMC(selective voluntary motor control) increases from the proximal to the distal joints.

Using an ethopharmacological technique, we demonstrated that saponin fraction from red ginseng root possessed a potent psychotropic actions on either intermale or maternal aggression models. A series of experiments clearly indicated that one of psychoactive ingredient is ginsenoside Rbl. Although a drug-induced debilitation of motor performance remains a possible cause of the antiaggressive affect of the drug. ginsenoside Rbl did not alter the locomotor activity of the mice during agonistic confrontations. Thus. one can eliminate the possibility that the psychotropic effect of ginsenoside Rbl might be concealed by a drug-induced impairment of motor performance. More recently, we developed a nevi model for copulatory disorder and introduced into the behavioral analysis of drug action. Male mice which has been housed individually from weaning for 5 weeks failed to manifest copulatory behavior when they encountered with the sexually receptive females. Daily administration of crude ginseng saponin during isolation housing period prevented the development of copulatory disorder, whereas both ginsenoside Rbl and Rgl were ineffective. A further experiment may be needed to explore active ingredient of ginseng saponins.

Carbon monoxide (CO) intoxication is a leading cause of the variable neuropsychiatric impairment. Despite of widely known central nerve system complications after CO intoxication, peripheral neuropathy due to CO poisoning is rare and has been under-recognized. We report interesting case of a 29-year-old male who suffered from motor weakness and sensory abnormalities in his lower extremity following acute CO intoxication. The patient revealed direct and indirect signs of peripheral neuropathy of the left inferior gluteal and sciatic nerve on magnetic resonance imaging.

The purpose of this literature review was to identify the physiological changes with aging. The results of this renew were to follows : We have seen a wide variety of such changes in the cells and in all organ systems. 1. At least 40 percent of people over 65 will die of cardiac disease, 15 percent of cerebrovascular disease, and possibly another 5 percent of other types of vascular impairment. 2. The increase rigidity of the thoracic wall and the decreased strength of the expiratory muscles decrease the propulsive effectiveness of the cough. 3. The density of capillaries per motor units is decreased. 4. Starting before age 40 in both sexes there is a shift from an increase in bone mass to a progressive decrease. 5. Histologic studies show a lim age-correlated decrease in the number of Pacini's. Merkel's, and Meissner's corpuscles.
