Abstract

This study examined the effects of the sleep quality of chronic stroke outpatients on their patterns of activity performance and quality of life. This study was conducted on 49 patients with chronic stroke who received outpatient care in hospitals in South Korea.The Pittsburgh Sleep Quality Index (PSQI) was used to examine sleep quality, the Occupational Questionnaire (OQ) was used to assess frequency of occupational participation; while the World Health Organization Quality of Life-BREF (WHOQOL-BREF)was used to measure quality of life. As the results of the analysis, it was shown that the patient group with higher quality of sleep in the surveyed chronic stroke outpatients were indicated to have the higher activity frequency in the work and daily living work in terms of their activity execution phase, whereas the patient group with higher quality of sleep the higher activity frequency in the field of the rest (p <0.05). In addition, the higher quality of sleep group showed statistically significant higher quality of life (p <0.05). The findings of this study showed that the sleep quality of outpatients with chronic stroke is related with their pattern of activity performance and quality of life, and that bad sleep quality may negatively affect their pattern of activity performance and quality of life.
