Correlation Between Saccadic Eye Movement, Activities of Daily Living, and Cognitive Function in Elderly Patients With Stroke

Abstract

This study aimed to analyze the correlation between saccadic eye movement, activities of daily living, and cognitive function in elderly patients with stroke, that could help establish interventions in clinical settings. This study included 32 elderly patients with stroke who were admitted to a medical center. The King-Devick test (K-D test), Korean version of the Modified Barthel Index (K-MBI), and Korean version of the Montreal Cognitive Assessment (MoCA-K) were used as evaluation tools. The correlation between evaluation scores was analyzed using Pearson’s correlation coefficient. The correlations between the total scores of the K-D test, K-MBI, and MoCA-K were statistically significant (p<0.01). In addition, the K-D test showed statistically significant correlations with personal hygiene, bathing, feeding, toilet, stair climbing, dressing, chair/bed transfer, ambulation, and wheelchair use in the K-MBI and visuospatial/executive, naming, delayed recall, and orientation in the MoCA-K. This study showed a correlation between saccadic eye movement, activities of daily living, and cognitive function in elderly patients with stroke. In the future, such studies with larger sample would help to establish interventions in clinical settings.
