Objective : This study evaluated the differences between the upper and lower arm activities of the affected and non-affected sides in stroke patients performing activities of daily living. It was intended to gather basic data for the measurement of daily activities. Methods : The participants in the study consisted of 20 patients, 10 had left hemiplegia and 10 had right hemiplegia. Between September and November 2017, they performed drinking and dressing as unimanual and bimanual tasks. The 3-axes accelerometers were placed 2cm below the lateral epicondyle on the upper arm and 2cm below the radial styloid on the lower arm. The data were collected at intervals of 1/32 Hz and analyzed. Results : In patients with right hemiplegia, the tendon activity was significantly higher in the lower arm when performing a bimanual activity (p<.05), for all the other activities, those of the lower arm were significantly higher than those of the upper arm (p<.01, p<.05). There was no significant difference between the unimanual and bimanual activities of the affected and tendon sides in patients with left hemiplegia (p>.05). In both hands, the activity of the lower arm was significantly higher than that of the activities of the upper and lower arms, except on the affected side (p<.05). In all patients, the activities of the upper and lower arms were significantly higher (p<.05), and the activity of the lower arm was significantly higher than that of the upper (p<.001, p<.05). Conclusion : The activity was higher on the non-affected side than the affected side during the dressing task, and the overall activity was higher in the lower arm than the upper arm.

Keyboard is a link between human and terminal, so we can input knowledge to information device. The misstyping is occured or the speed is reduced if there would be transmission error. We always have to consider human interface and behavior effect, because the keyboard system is the harmony of human and machine. This paper is designed for representation of ortho-phonics alpabetic one hand strock keyboard which is enable to correct error and to edit word.

Objective : The purpose of this study was to investigate the effects of bimanual intensive training on Upper Extremity Function and activities of daily living in stroke patients. Methods : The subjects were 18 patients who were diagnosed with hemiplegic stroke. They were randomly assigned to bimanual intensive training group (n=9) and unilateral intensive group (n=9). Bimanual training group performed bimanual task and unilateral training group performed one hand task for 1 hour per session, 5 times a week, for 4 weeks. Chi-square test, Wilcoxon signed rank test, and Mann-Whitney U test were used for analysis. Results : The results showed that, upper extremity motor function and bimanual coordination were significantly improved in patients in the bimanual training group (p<.05). Additionally, the ratio of affected hand use and amount of use/quality of movement in the hemiplegic upper extremity in activities of daily living for patients in the bimanual training group were significantly improved (p<.05). Although the unilateral group improved motor upper extremity function and activities of daily living in the upper extremity (p<.05), it was not significantly different from that in the bimanual training group. In between-group comparison, bimanual coordination and ratio of the affected hand use in a day were significantly different (p<.05). Conclusion : It is reasonable to conclude that bimanual intensive training therapy is an effective intervention method to improve upper extremity motor function, and activities of daily living in stroke patients.
