Objectives: We investigated injury of corticostriatal (CStr) tract in patient with mild traumatic brain injury (mTBI), which was demonstrated by DTT. Method: A 44-year-old female with no previous history of neurological, physical, or psychiatric illness had suffered from head trauma resulting from a pedestrian car accident. She complained that could not quickly move the left hand with her intension. After three month's administration, her slowness movement of left hand recovered rapidly to the point that she was able to extend all fingers quickly. Results: On DTT configuration, the integrity of the left CStr tract was well-preserved, however the right CStr tract showed narrowing and partial tearing in the subcortical white matter on a DTT at 25 months after onset. Conclusion: Injury of the right CStr tract was demonstrated in a patient who developed mild motor control problems following mild TBI. We believe that the evaluation of the CStr tract from the secondary motor area for patients who showed unexplained motor control problem is necessary.

EEG-based brain computer interface (BCI) provides a new communication channel between human brain and computer. The classification of EEG data is an important task in EEG-based BCI. In this paper we present methods which jointly employ principal component analysis (PCA) and linear dynamical system (LDS) modeling for the task of EEG classification. Experimental study for the classification of EEG data during imagination of a left or right hand movement confirms the validity of our proposed methods.

Purpose: This research with one group pre-post design was carried out to test the practical feasibility to administrate the Music Movement program developed for the stroke patients. Subjects: 12 stroke survivors at "J" Public Health Center in Seoul. were participated in. The average age was 68 years old, the ratio of sex was almost 5.8:4.2, the duration of was almost over 1 year. Method: Music Movement program was conducted for 2 hours ${\times}$ 1day ${\times}$ 6 weeks. The contents of Music Movement program were consisted of the preparatory activities, main activities and the wrap up activities. The preparatory activities are ice braking, greeting, explanation of the aims of music movement program, and introduction of stroke disease and ROM exercise. The main activities are the body motions with singing and playing musical instruments. The wrap up activities are stretching and joints and discussion of home activities. Data Collection: The outcome variables are muscle strength, finger pinch power, ROMs, flexibility, depression, and life satisfaction. Depression was measured by CES-D(Kim, I. J., 1999), life satisfaction by ladder scale(McDowell & Newell, 1996), and ADL state(Holbrook & Skilbeck, 1983). Data Analysis: SPSS/PC 10.0 for Window was used. Wilcoxon Signed Ranks Test was used to analyze outcome measures. The level of statistical significance was set at p<.05. Results: This program was effective to decrease the depression level of subjects(p<.05). The muscle strength, hand grip power, ROMs, life satisfaction, and rehabilitation state of the subjects were slightly increased but no significant differences were found between the pre and post test. Additionally every patient replied that they were very satisfied and expressed their appreciation for this program very much. Of course they strongly want to continue to participate in and meet the peer group again. Conclusion: Considering these results, the practical feasibility of Music Movement program can be supported. Therefore, this Music Movement program can be examined with the quasi-experimental design with control group and ongoing reviews. After that, this program would be applied in public health centers, medical institutes, and welfare centers for the rehabilitation of stroke patients.

Constraint-Induced Movement Therapy(CIMT) is considered as one of the most interesting upper extremity rehabilitation in the field of neurorehabilitation. CIMT is an intensive training provided in the affected upper limb for 6 hours a day, 5 days a week for 2 weeks, while unaffected arm is restrained for 90% of waking hours. Recently, instead of CIMT, modified Constraint-Induced Movement Therapy(mCIMT) has been applied because of the clinical limitations of CIMT. CIMT or mCIMT studies have used various outcome instruments to measure different aspects of upper limb function after intervention. There are various kinds of evaluation tools to measure different aspects of upper limb function after CIMT intervention. It has been proven that Pediatric Motor Activity Log(PMAL), Quality of Upper Extremities Skills Test(QUEST), Melbourne Assessment of Unilateral Upper Limb Function(MAULF), Assisting Hand Assessment (AHA) are effective. The purpose of this study was to investigate the cortical change in children with hemiplegic cerebral palsy after CIMT. As a result, use-dependent cortical reorganization was revealed. Also, increased activity of the contralateral motor cortex and decreased activity of the ipsilateral cortex were found. It supports the mechanism of cortical reorganization, the principles of neural plasticity and specifically activation of the contralateral cortex, for improving upper limb function after CIMT.

Objective: This study aims investigating the effects of functional electrical stimulation (FES) on hand function of children with spastic cerebral palsy. Methods: The participants of this study are 20 children with spastic cerebral palsy aged between 11 to 16 years old. All the subjects underwent 24 sessions of FES during 8 weeks. Each FES was 20 minutes per session, and 3 sessions of FES were provided in a week. Measurements used to assess hand function are Jebsen Hand Function Test, Modified Ashworth Scale and 3D Motion Analysis. After establishment of the baseline for each client by all the measurements, reevaluations were performed every 2 weeks using Jebsen Hand Function Test and the Modified Ashworth Scale. The 3D Motion Analysis was performed only before- and after the 8 weeks of FES treatment. Results: After the FES, there was significant decrease in completed time for the all 6 subtasks of Jebsen Hand Function Test were (p<.05) and also significant decrease in spasticity score of Modified Ashworth Scale as well (p<.05). 3D Motion Analysis showed that the hand tapping and the finger tapping has been significantly improved (p<.05), and the pronation-supination movement of lower arm has been significantly improved as well. Conclusion: Based on the results of this study, it is evidenced that functional electrical stimulation is effective treatment for hand function of children with cerebral palsy. For future research, it is recommended to examine various protocols of FES including impact of long-term application.

The purpose of this study was to investigate the relations between the segments of the body, the three dimensional anatomical angle during One Hand Backhand Stroke and Two Hand Backhand in tennis. For the movement analysis three dimensional cinematographical method(APAS) was used and for the calculation of the kinematic variables a self developed program was used with the LabVIEW 6.1 graphical programming(Johnson, 1999) program. By using Eular's equations the three dimensional anatomical Cardan angles of the joint and racket head direction were defined. 1. In three dimensional maximum linear velocity of racket head the X axis and Y axis(horizontal direction) showed $-11.04{\pm}2.69m/sec$, $-9.31{\pm}0.49m/sec$ before impact, the z axis(vertical direction) maximum linear velocity of racket head did not show at impact but after impact this will resulted influence upon hitting ball. It could be suggest that Y axis velocity of racket head influence on ball direction and z axis velocity influence on ball spin after impact. The stance distance between right foot and left foot was mean $75.4{\pm}5.86cm$ during one hand backhand stroke and $72.6{\pm}4.67cm$ during two hand backhand stroke. 2. The three dimensional anatomical angular displacement of trunk in interna rotation-external rotation showed most important role in backhand stroke. and is follwed by flexion-extension. the three dimensional anatomical angular displacement of trunk did not show significant difference between one hand backhand stroke and two hand backhand stroke but the three dimensional anatomical angular displacement of trunk was bigger than one hand backhand stroke. 3. while backhand stroke, the flexion-extension and adduction-abduction of right shoulder joint showed significant different between one hand backhand stroke and two hand backhand stroke. the three dimensional anatomical angular displacement of right shoulder joint showed more flex and abduct in one hand backhand stroke. 4. The three dimensional anatomical angular displacement of left shoulder showed flexion, adduction, and external rotation at impact. after impact, The angular displacement as adduction-abduction of left shoulder changed motion direction as abduction. angular displacement of left shoulder as flexion-extension showed bigger than the right shoulder.

The purpose of this research was to analyze how the evaluation method affects the subjective hand evaluation of fabrics and to suggest the efficient evaluation method. Three methods such as the sense of sight ＆ touch, the sense of touch, and the sense of sight were respectively used when judges estimated the hand of fabrics using questionnaire. The result obtained by the method of touch was same as that by the method of sight ＆ touch. The time required for the evaluation by these two methods was statistically same. Consequently, the method of touch has no attraction compared to that of touch ＆ sight. In case of using the method of sight, 8 properties among 10 showed the same results as in the method of sight ＆ touch. The properties of [moogupda/kabyupda] and [shinchuksung-e-itda/ shinchuksung-e-upda] evaluated with the sense of sight were different from the results obtained by the other methods. These properties seem to be difficult to evaluate only by seeing the fabric on the table. For the precise evaluation, it is necessary to show dynamic movement of the fabric. The time required for the evaluation by the sense of sight was shorter than that by the other two methods.

This paper presents hybrid control of displacement and force in a Medical Tele-Analyzer by disturbance observer-based controller which is robust to internal and external disturbances; model uncertainty, load, and friction for instances. The developed Medical Tele-Analyzer consists of 2 subsystems; doctor-side subsystem and patient-side subsystem. In the doctor side subsystem, an array of displacement sensor is equipped to detect movement of doctor's hand and fingers. The detected information is transmitted to the patient side to be used in medical analysis. On the other hand, the patient-side subsystem consists of an array of displacement actuators, which is used to follow displacement of doctor's hand and fingers. An array of force sensors is used to detect forces between patient and the equipment. Since displacement control in patient side is coupled with force control in doctor side and vice-versa, design of the controller has to take into account this coupling. Not only using in medical tele-analysis, the proposed system can also be used in any tele-displacement-force controls of industrial processes.
