  • Aerial parts of Sida rhombifolia Linn. (Malvaceae) were extracted successively using various solvents and screened for various parameters of antiarthritic activity such as adjuvant-induced arthritis, motor performance, and histopathological study. The ethanol and the aqueous extracts showed potent activity; further these extracts were fractionated by using column chromatography. The fraction ET1 isolated from ethanol extract showed the most potent antiarthritic activity.

  • The purpose of this study was to investigate the effect of the home-based virtual reality (VR) on upper extremity motor function in hemiparetic stroke patients. Two matched subjects with left hemiplegia were volunteered to participate in this study. One subject received the home-based VR whereas the other subject recovered a modified home-based constraint-induced movement therapy (CIMT). Both interventions were given for 4 hours x 5 times a week for 4 weeks. Outcome measures included Fugl-Meyer Assessment (FMA), Motor Activity Log (MAL), and Wolf Motor Function Test (WMFT). The VR-trained subject showed considerable improvement in all the tested motor functions when compared with the home-based CIMT. Specifically, the FMA measure demonstrated that the VR subject showed 17% enhancement whereas the CIMT subject showed 5% increase. Similarly, Amount of Use (AOU) and Quality of Movement (QOM) of the MAL scores of the VR subject showed 40% and 20% increase whereas the CIMT subject showed 0% and 20% increase, respectively. The WMFT scores of the VR subject and CIMT subject showed 20% increase. Our home-based VR was effective in upper extremity motor recovery of chronic hemiparetic patients even when compared with the well-established CIMT approach in stroke victims.

  • Goal of this study is to perform the correlation about Gross motor function, eating-drinking function, and oral motor function, to identify necessity for invervention of feeding disorders on severity of the function of children with cerebral palsy. Subjects were 61 children diagnosed with cerebral palsy. The subject were evaluated for oral motor function, feeding function by GMFCS, EDACS, OMAS. The results of this study showed a significant correlation between gross motor function, eating and drinking functions, and oral motor functions. That is, the more severe the deterioration of the motor function, the lower the functional level of eating and drinking and oral motor function deterioration. In evaluating and treating the eating activity of children with cerebral palsy through this study, it seems necessary to check the eating and drinking function and oral motor function according to the gross motor function.

  • Background: Studies suggest that induced emotional changes can affect the sensory-motor system involved in the practice of muscle activity and movement in physical aspects. Previous studies have shown focused on effects just feedback on muscle activity associated with emotions but rarely have focused induced emotional change on gross motor function such as muscle activity. Objects: The purpose of this study was to compare biceps activity and emotion that before and after viewing a video was induced positive or negative emotion. Methods: The study enrolled 34 healthy male and female who scored at normal points on the Center for Epidermiological Studies-Depression Scale. The study measured over two weeks, showing subjects pleasant and sad videos one by one in a week. We performed to measure the biceps brachii activity which is maximal voluntary isometric contraction (MVIC) and the visual analog mood scale (VAMS) scores before and after one week. The significance level was set to α = 0.05. Results: There was no significant difference in muscle activity of the biceps brachii before and after each video was viewed (p > 0.05). However, the visual analogue mood scale showed an increase in VAMS after viewing each video (p < 0.05). Conclusion: We figured out induced emotional changes are cause actual emotional changes but there are no differences in muscle activity. In this research, watching the video with a short time looks like insufficient to change muscle activity. Nevertheless, there might be different when we check various muscles with sufficient time for viewing the video. Further study is needed to measure a variety of muscles with more time for viewing the video.

  • Purpose: The cerebellum is a region of brain structure that plays an important role in calibrating two different information of neural signal from descending motor commands and from ascending sensory inputs. Damage of the cerebellum shows a variety of classic motor symptoms such as postural and locomotor dysfunctions. Therefore, we tried to investigate motor function and skill in stroke patients with cerebellar lesions in sub-acute stage, and compare with these functions of patients with non-cerebellar lesions. Methods: Total twelve stroke patients with cerebellar lesion and 130 stroke patients with non-cerebellar lesions were retrospectively recruited in this study. For evaluation of motor strength, Motricity index (MI) for upper and lower limbs was tested. For measurement of motor skill function, the modified Brunnstrom classification (MBC), Manual function test (MFT), functional ambulatory category (FAC), and Barthel index were adopted. Results: In comparison of motor strength and motor skill function between two groups, statistical differences between the two groups were significantly observed only in upper MI and FAC. Although no significant differences were found in other variables, stroke patients with cerebellar lesion had higher scores in lower and total MI, MBC, and MFT, whereas they had lower scores in FAC and Barthel index. Conclusion: Our results showed that stroke patients with cerebellar lesion had greater impact on movement functions related to hand motor and walking ability in activities of daily life, compared with patients with non-cerebellar lesion, in spite of similar degree of motor function and skill between the two different lesioned-groups.

  • This study was undertaken to determine effect of Zusan1i(ST36) acupuncture (AP) on the small intestinal motility in the rabbit. Changes in the motility in vivo of ileum was measured before and 20 min. after AP. In order to examine whether AP effect was affected by autonomic nerves, norepinephrine or acetylcholine was applicated. AP significantly increased the mean wave amplitude and motor index, but not the mean wave duration and motor activity. Infusion of norepinephrine ($2{\mu}m$) into an ear vein resulted in a decrease in the mean wave amplitude and motor index, which was not affected by AP. Acetylcholine ($10{\mu}m$) produced inhibition followed by stimulation of motility. The stimulation of motility was induced by an increase in the mean wave amplitude and motor index, but not the mean wave duration and motor activity. The effect of acetylcholine was not significantly different between before and after AP. These results suggest that Zusan1i(ST36) acupuncture stimulates the small intestinal motility, which is not mediated by autonomic nerves. Therefore, Zusan1i(ST36) acupuncture seems to be applicable to impaired small intestinal movement.

  • While a great number of studies on human motor control have provided a wide variety of viewpoints concerning the strategy of the central nervous system (CNS) in controlling limb movement, none were able to reveal the exact methods how the movement command from CNS is mapped onto the neuromuscular activity. As a preliminary study of human-machine interface design, the characteristics of human leg motion and its underlying motor control scheme are studied through experiments and simulations in this paper. The findings in this study suggest a simple open-loop motor control scheme in leg motion. As a possible candidate, an equilibrium point control model appears consistent in recreating the experimental data in numerical simulations. Based on the general leg motion analysis, the braking motion by the driver's leg is modeled.

  • On-line monitoring system(OMS) has been developed for the pumped storage generator/motor The OMS is applied to diagnosis of the PD(partial discharge) activity of stator insulation, the shorted-turn of rotor winding and the variation of the air-gap between stator and rotor. The OMS consists of DAS(data acquisition system), main server system, gateway and display PC. The DAS measures the PD, the shorted-turn and air-gap from three sensors installed on the generator/motor. The gateway controls the data which sent by DAS. The main server system saves the data, analyzes the data and conducts the diagnostic algorithm. The display PC shows the diagnostic results of partial discharge, shorted-turn and air-gap. Field tests were conducted using PDA(partial discharge analyzer). The results of the OMS and PDA measurements can be directly correlated with normalized quantity number(NQN), PD magnitude(Qm) and PD pattern.
