뇌졸중 환자에서 시간경과에 따른 환측 도형인지능력의 변화

Shape Cognitive Ability’s Changes from the Affected Side According to Time Lapse in Stroke Patients

Objective : This study is aimed to investigate on which changes of shape cognitive abilities are showed at unilateral paralyzed patients according to time lapses, and what effects are influenced to recovery degrees such as cognitive function, upper extremity function, recovery phase, and daily life action etc. Methods : Research objects were 17 unilateral paralyzed patients with 12 males and 5 females who have hospitalized and discharged from the D hospital located in Banghak-dong, Seoul during July-October 2010. Objects were composed of 9 right paralyzed patients and 8 left ones. For these patients, reevaluation was carried out after 6 months from executing initial evaluation. This study observed and compared cognitive abilities to 9 figures having various lengths and thicknesses of alphabet T and I panels along with ○,△,□ ones from sagittal section and forehead one by using tablet. The study compared with recovery degrees such like cognitive function with MMSE-K, upper extremity function with MFT, recovery phase with Brunnstrome, and daily life actions with MBI. Results : First, there were a little difference in graphic cognitive abilities between initial evaluation and reevaluation at forehead section, but it was not significant. In sagittal section, graphic cognitive abilities between initial evaluation and reevaluation showed significant differences from distances along with sum of directions and distances(P<.05). Second, changes of functional recovery levels according to time lapses did not show significant differences at all items such as cognitive function, upper extremity function, recovery phase, and daily life actions etc. Third, in the graphic cognitive abilities between right paralyzed patients and left ones according to time lapses, right paralysis was higher with average 1.92 point at forehead section, average 1.95 at sagittal section than left one, and showed significant differences(P<.05). Also, there were differences at the time of reevaluation, but it was not significant. Conclusion : This study lighted up a fact that there were differences in changes of graphic recognition according to time lapses. However, it is necessary to clear up cognitive process s characteristics of unilateral paralyzed patients who have not considered till now further concretely along with various aspects through additional researches.
