Purpose: This purpose of this study was to investigate the effects of initial cognitive status on the recovery of functional status in patients with subacute stroke.
Methods: The participants were 111 patients with subacute stroke, divided into two groups: mini-mental state examination (MMSE) <20 (n=49) group and MMSE ≥20 (n=62) group. Clinical evaluation scores were collected before and after rehabilitation. The repeated measurements ANOVA was used to confirm the changes in functional status before and after intervention in the two groups. Changes in functional status within the group were examined through a paired test. A Pearson correlation coefficient analysis was performed to identify the correlation between MMSE change amount and functional status score.
Results: In each of the two groups, according to the initial cognitive status, the clinical evaluation score increased statistically significantly, but there was no difference between the two groups in the degree of significant increase. When examining the correlation between the MMSE change amount, according to the initial cognitive state and the functional state score change amount, it was found, only in the group with MMSE <20, that the larger the change in the MMSE score, the greater the functional state change of Berg balance scale, Rivermead Mobility Index, and motor assessment scale. This did not apply to the group with MMSE ≥20.
Conclusion: Initial cognitive status should be considered when setting the patient’s goal, and considering cognitive improvement when constructing a rehabilitation program is thought to have a positive effect on rehabilitation services.
