Background and Purpose: Stroke-induced focal brain lesions often exert remote effects via residual neural network activity. Electroencephalographic (EEG) techniques can assess neural network modifications after brain damage. Recently, EEG phase synchrony analyses have shown associations between the level of large-scale phase synchrony of brain activity and clinical symptoms; however, few reports have assessed such associations in stroke patients., Objective: The aim of this study was to investigate the clinical relevance of hemispheric phase synchrony in stroke patients by calculating its correlation with clinical status., Methods: This cross-sectional study included 19 patients with post-acute ischemic stroke admitted for inpatient rehabilitation. Interhemispheric phase synchrony indices (IH-PSIs) were computed in 2 frequency bands (alpha [α], and beta [β]), and associations between indices and scores of the Functional Independence Measure (FIM), the National Institutes of Health Stroke Scale (NIHSS), and the Fugl-Meyer Motor Assessment (FMA) were analyzed. For further assessments of IH-PSIs, ipsilesional intrahemispheric PSIs (IntraH-PSIs) as well as IH- and IntraH-phase lag indices (PLIs) were also evaluated., Results: IH-PSIs correlated significantly with FIM scores and NIHSS scores. In contrast, IH-PSIs did not correlate with FMA scores. IntraH-PSIs correlate with FIM scores after removal of the outlier. The results of analysis with PLIs were consistent with IH-PSIs., Conclusions: The PSIs correlated with performance on the activities of daily living scale but not with scores on a pure motor impairment scale. These results suggest that large-scale phase synchrony represented by IH-PSIs provides a novel surrogate marker for clinical status after stroke.

[Purpose] Our purpose was to create awareness among of social rehabilitation at the university and in local governments, to identify gaps in social rehabilitation, and to increase the effectiveness of social rehabilitation. [Subjects and Methods] This study included stroke patients undergoing physical rehabilitation from the stroke outpatient clinic (43 patients) and the Istanbul Metropolitan Municipality Home Care Service (101 patients); face-to-face interviews were conducted to collect patient information regarding nutritional status. In addition, baseline functional independence measure (FIM) scores at baseline and during three months of follow-up were also compared. [Results] The average FIM motor scores at three months did not differ significantly between the home and hospital treatment groups. However, there were significant differences in baseline FIM motor and cognitive scores and three-month follow-up scores as well as average FIM total baseline scores between groups. In addition, month-to-month analysis of changes in FIM values between the two groups also revealed significant differences. [Conclusion] The results of our study were concordant with those of previous studies of stroke patients receiving rehabilitation, in demonstrating improved patient functional and cognitive capacity.
