Purpose This study was to identify effect on Center of Pressure(COP) by designing program for dual task using cell phone and foot position. Methods Subjects were instructed In the study among stroke inpatient in rehabilitation clinic, Y&P Hospital located in Suwon & Pyeongtaek, Gyeonggi, 11 inpatients for four position were selected, and effect of four position on their respective COP length, COP velocity, affected and unaffected weight bearing ration were examined. COP length and velocity measured by Zebris during four position(Comfortable foot position, N1/Comfortable foot position with dual task using cell phone, N2/ Closed foot position, F3/ Closed foot position with dual task using cell phone, F4) Results Participants showed N3 group's COP length and velocity significantly increase compared with N1 group. But N2, F4 group's COP length and velocity non-significantly increase compared with N1 group. Unaffected side weight bearing ratio significantly high compared with affected side. Conclusion These findings Closed Foot position of patients with chronic stroke increases posture sway on standing position control.

Purpose The purpose of this study was to determine the effects of visual motor function and gross motor function, through to conduct dual task training include eye movement into children with spastic cerebral palsy with ocular anomalies. Methods The subjects of this study were 6 children with spastic cerebral palsy with ocular anomalies. The experimental group (n=3) received the dual task training include eye movement and control group (n=3) received the dual task training each for 30 minutes a day, twice a week for 8 weeks. Before and after the intervention were evaluated using VMI and GMFM. Results The results of this study were as follows; First, comparisons of group within VMI and GMFM values are as follows; The experimental group had no significant difference between the VMI and GMFM before intervention and after (p＞.05). But, effect sizes had on effect on the GMFM A (d = 0.6), GMFM D (d = 0.7), GMFM total score (d = 0.5) The control group had no significant difference between the VMI and GMFM before intervention and after (p ＞.05). But, effect sizes had on effect on the GMFM total score (d = 0.6). Second, comparisons between groups after intervention of VMI and GMFM value were as follows; The comparison between groups had no significant difference after intervention of VMI and GMFM all (p > .05). But, effect sizes had an effect on the GMFM C (d = 0.6). Conclusion As a result, the dual task including eye movement goes along for 8 weeks was no significant difference for improving the VMI and the GMFM in children with spastic cerebral palsy with ocular anomalies.However, it gave show that this has been a partial effects. Therefore if the future progress in the study that complement the limitations of the study, it will be considered that there can be obtained a significant result.
