뇌졸중 환자에서 장기적인 기능 변화와 관련된 요인 분석

초록

Objective To investigate long-term functional changes and its underlying factors in stroke patients. Method Data were collected retrospectively from the stroke patients who had been completed at least 2 times of functional evaluation after discharge. 60 stroke patients were included and we investigated long-term change of motor, cognition and activities of daily living score at 6 months from the onset and the last score during the follow up period. The motor function included manual function test (MFT), Korean version of Berg balance scale (K-BBS), cognitive function by Korean version of mini-mental status examination (K-MMSE), activities of daily living by Korean version of modified Barthel index (K-MBI). To identify the factors influencing long-term function outcome after stroke, biographical data and risk factors were collected and bivariate correlation analysis was performed. Results The mean duration of follow-up was 23.4 months and MFT, BBS, MMSE, and K-MBI scores showed no significant difference between 6 months from the onset and final evaluation. History of recurrent stroke (p = 0.007) and hypertension (p = 0.017) were significantly related with decline of cognition during follow up period. All the other independent variables were not statistically significant. Conclusion None of the function showed significant changes during the 2 year of mean follow-up period. Recurrent stroke and hypertension were significant predictor for decline of cognitive function. Our results suggest that secondary prevention including blood pressure control is important to prevent decline of cognitive function after stroke.
