Objective : The purpose of this study was to estimate the reliability of cervical range of motion measurement in healthy adults using smart phone application and goniometer that can be easily applicated in clinical setting. Methods : The cervical range of motion was measured as the flexion, extension, right rotation, left rotation, right lateral flexion, and left lateral flexion. To measure the reliability of intra-rater and inter-rater reliability, the same examiner performed two measurements and the other examiner performed once, total measurement were performed three times. The order of tests was randomized and two examiners didn't know the results of measurements. Results : Thirty healthy adults were participated. The result of this study shows that there were are no significant differences in all movements except the right lateral flexion in comparison of average angle of smart phone application and goniometer. The intra-rater reliability of smart phone application and goniometer showed ICC as .841∼.958 and the inter-rater reliability showed ICC as .720∼.944 for all movements. Conclusion : These results suggest that smart phone application and goniometer have proven to be reliable in measuring the cervical range of motion. Smart phone application can be used as a useful tool in clinical setting due to fast and accurate measurements of cervical range of motion.

Objective : The aims of this study was to investigate the effects of modified constraint induced movement therapy(CIMT) on upper extremities function of children with hemiplegic cerebral palsy. Methods : The participants of this study are 4 children with hemiplegic cerebral palsy aged between 8 to 11 years old. During the modified CIMT period, the unaffected hand of the subjects was restrained by a hand splint for 8 weeks, five days per week, five hours a day. And the affected upper extremity was strongly trained by performing functional tasks, which were individually structured use of the affected arm. Measurements used to assess hand function are Jebsen Hand Function Test, and 3D Motion Analysis. The Jebsen Hand Function Test was performed repeatedly every two weeks. The 3D Motion Analysis was performed before and after the 8 weeks of modified constraint induced movement therapy. Results : After the modified CIMT, there was a significant improvement in completed time for the 6 tasks of Jebsen Hand Function Test(p<.05). 3D Motion Analysis was that the finger tapping and the hand tapping has been significantly decreased (p<.05), and the pronation-supination movement has been significantly increased as well(p<.05). Conclusion : In the results of this study, it is evidenced that modified CIMT is effective treatment for upper extremities function of children with hemiplegic cerebral palsy. For future research, it is recommended to examine various periods and protocol of modified CIMT including impact of long periods application.

Objective : The main purpose of this study was to analyze factors affecting a health related quality of life(HRQOL) in the elderly stroke patients with(Group 1) or without(Group 2) sequela. Methods : This survey performed secondary analysis with 'the fifth korea national health and nutrition examination survey', and investigated 91 elderly stroke patients over 65 years. Results : The results were as followed: HRQOL and self rated health had a significantly lower in Group 1(p<.05). In all groups, HRQOL was affected by self rated health(β=0.39), mental health, and medical health significantly(p<.05). In group 1, HRQOL was affected by mental health(β=0.45), self rated health significantly(p<.05). In group 2, HRQOL was affected by medical health(β=0.45), functional health, mental health significantly(p<.05). Conclusion : In order to improve the HRQOL of stroke patients during rehabilitative therapy, it is important that early detection and early intervention of depression and suicide, which affect mental health status, are important in the case of severe aftereffects. If the patient continues to support his/her current status regardless of aftereffects, he/she can improve the HRQOL with functional recovery of the stroke patient, and finally have a positive effect on the independence of the stroke patients.
