Objective: This study aimed to quantify one of the useful upper extremity movements to evaluate motor control abilities between the groups of people with mild and moderate arm impairments performing a door handling task. Design: Cross-sectional study. Methods: Twenty-one healthy participants and twenty-one persons with chronic stroke (9 mild stroke and 12 moderate stroke) were recruited for this study. Stroke participants were divided into 2 groups based on Fugle-Meyer Assessment scores of 58-65 (mild arm) and 38-57 (moderate arm). All they performed door handling task including the pronation and supination phases 3 times. We measured some movement factors which were reaction time, movement time, hand of peak velocity, hand of movement units to perform door handling task using the three-dimensional motion analysis. Results: The majority of kinematic variables showed significant differences among study groups (p<0.05). The reaction time, total and phase of movement time, hand of peak velocity, the number of movement units discriminated between healthy participants and persons with moderate upper limb stroke (p<0.05). In addition, reaction time, total and phase of movement time, the number of movement units discriminated between those with moderate and mild upper limbs of stroke patients (p<0.05). Conclusions: Three-dimensional kinematic motion analysis in this study was a useful tool for assessing the upper extremity function in different subgroups of people with stroke during the door handling task. These kinematic variables may help clinicians understand the arm movements in door handling task and consist of discriminative therapeutic interventions for stroke patients on upper extremity rehabilitation.

NREX, an upper limb exoskeleton robot, was developed at the National Rehabilitation Center to assist in the upper limb movements of subjects with weak muscular strength and control ability of the upper limbs, such as those with hemiplegia. For the free movement of the shoulder of the existing NREX, three passive joints were added, which improved its wearability. For the flexion/extension movement and internal/external rotation movement of the shoulder of the robot, the ball lock pin is used to fix or rotate the passive joint. The force and torque between a human and a robot were measured and analyzed in a reaching movement for four targets using a six-axis force/torque sensor for 20 able-bodied subjects. The addition of two passive joints to allow the user to rotate the shoulder can confirm that the average force of the upper limb must be 31.6% less and the torque must be 48.9% less to perform the movement related to the axis of rotation.

Active movement is able to actively contract his muscles and move a segment either with or without assistance. This movement maintain physiologic elasticity and contractility of the participating muscles, provide sensory feedback from the contracting muscles and stimulus for bone integrity as well as increase circulation and prevent thrombus formation, in addition to develop coordination and moor skills for functional activities. Passive movement is the motion to the external force; gravity, machine, another individuals. Active movement is more activated rather than passived on the central nervous system. Therefore, we think that active movement is more effected facilitating through specific inhibitory mobilization of muscle.

Objectives : The purpose of this study was to understanding the constraint induced movement and Self-efficacy with arm training on upper motor function in Stroke Patients. Methods : Stroke, the leading cause of functional disability, causes a variety of impairments that compromise quality of life. Upper limb hemiparesis, a commonly seen impairment, is particularly problematic given its impact on activities of daily living. Because stroke was a disease to correspond to the first during domestic cause of death, and was accompanied by a lot of side aftereffects after a survival, stroke rehabilitation bought a patient and a family and a physical therapist, and it was main concern of. Results : Looks into upper extremity excrise of a subacute stroke patient estranged a acute convalescence later by a rehabilitation treatment in this consideration, and evaluates an effect to wind up constraint induced movement for an early treatment of stroke and Self efficacy, and help is one to an early rehabilitation of an stroke patient. Conclusions : Overuse sound tends after the stroke occurrence in the early stage in order to recompense for stroke, and at the time of a new aspect called learned nonuse syndrome by a movement of a paralysis part dusting off wealth with this step thing later. Constraint induced movement using self efficacy could be an effective for improving function of stroke.

Purpose : This study attempts to assist stroke patients lead independent daily life movements by providing basic data for stroke patients' successful rehabilitation program and understanding the relationship between health beliefs of stroke patients and their guardians, and patients' rehabilitation performance level and daily life movement fulfillment ability. Methods : 23 stroke patients receiving treatments at rehabilitation specializing hospital after getting diagnosed with a stroke, along with 23 guardians were selected as research subjects, and health belief was measured by modifying supplementing Byun Young-Hee(2002)'s health belief measurement tool for leg movement disorder patients. Research findings revealed the following relationship between health beliefs of stroke patients and their guardians, and patients' rehabilitation performance and daily life movement fulfillment ability. Results : The patients group's initial MBI score was $33.13{\pm}3.46$, and measurement after four weeks was $38.43{\pm}3.47$. As health beliefs got stronger, MBI score increased significantly(p<.05). Correlation analyses of factors that affect rehabilitation attendance rate showed that perceived susceptibility, seriousness and usefulness were statistically significant, and perceived disability was not statistically significant(p<.05). Guardians' health belief index(susceptibility, seriousness, usefulness, disability) had no correlation with rehabilitation attendance rate. Conclusion : In order to increase daily life movement fulfillment ability of patients who are being treated with stroke, health beliefs must be raised to increase changes in daily life movement fulfillment ability. Therefore, it is believed that managing programs that can increase health beliefs of stroke patients can allow patients obtain positive health beliefs, further increase rehabilitation performance rate of stroke patients as well as independent daily life ability.

We investigated the activation of the cerebral cortex during active movement, passive movement, and functional electrical stimulation (FES), which was provided on wrist extensor muscles. A functional magnetic resonance imaging study was performed on 5 healthy volunteers. Tasks were the extension of right wrist by active movement, passive movement, and FES at the rate of .5 Hz. The regions of interest were measured in primary motor cortex (M1), primary somatosensory cortex (SI), secondary somatosensory cortex (SII), and supplementary motor area (SMA). We found that the contralateral SI and SII were significantly activated by all of three tasks. The additional activation was shown in the areas of ipsilateral S1 (n=2), and contralateral (n=1) or ipsilateral (n=2) SII, and bilateral SMA (n=3) by FES. Ipsilateral M1 (n=1), and contralateral (n=1) or ipsilateral SII (n=1), and contralateral SMA (n=1) were activated by active movement. Also, Contralateral SMA (n=3) was activated by passive movement. The number of activated pixels on SM1 by FES ($12{\pm}4$ pixels) was smaller than that by active movement ($18{\pm}4$ pixels) and nearly the same as that by passive movement ($13{\pm}4$ pixels). Findings reveal that active movement, passive movement, and FES had a direct effect on cerebral cortex. It suggests that above modalities may have the potential to facilitate brain plasticity, if applied with the refined-specific therapeutic intervention for brain-injured patients.

The aim of this study was performed to determine the inter-rater reliability of the Stroke Rehabilitation Assessment of Movement (STREAM) translated in Korean. This was a new clinical measurement tool for evaluating the recovery of voluntary movement and basic mobility following stroke. A direct-observation reliability study was conducted on 20 patients who had strokes and were in a rehabilitation setting. Subjects were assessed by two physical therapists. The reliability of the STREAM scores was demonstrated by weighted kappa statistics for inter-rater agreement on scores for individual items ranged from .83 to 1.0, intraclass correlation coefficients for total score was .99, and for subscale scores was ranged from .96 to .99. The internal consistency of the STREAM scores was demonstrated by Cronbach alphas of greater than .99 on the subscales and overall. These high levels of reliability support the use of the STREAM translated in Korean instrument for the measurement of motor recovery following stroke.

Proprioception means the ability to perceive the sensation of position and movement of body. As it is transmitted to central nervous system and used in feed-back or feed-forward motor control, proprioception allows us to keep our normal movement and normal balance activity. However, the conditions such as injury, disease, aging and fatigue can damage the proprioceptiive sensation of position, movement and lead to a functional impairment and additional damages in musculoskeletal system, because they alter the amount of proprioceptive ability that transfer into the central nervous system. The purpose of this study was to identify the definition and the function of proprioception, to look into variations in injury, disease, aging and fatigue that can be easily met in clinical application and eventually to provide valuable aid for assessment and treatment.
