This meta-analysis showed evidence that BCI training added to conventional therapy may enhance motor functioning of the upper extremity and brain function recovery in patients after a stroke. Covariates such as training duration, impairment level of the upper extremity, and the combination of both did not show significant effects on the overall pooled estimate. BCI training enhanced brain function recovery with an SMD of 1.11 (95%CI: 0.64 to 1.59 95%PI ranging from 0.33 to 1.89). An SMD of 0.41 (95%CI: − 0.29 to 1.12) for motor function recovery of the lower extremity was found. Quantitative analysis showed that a BCI training compared to conventional therapy alone in patients after stroke was effective with an SMD of 0.39 (95%CI: 0.17 to 0.62 95%PI of 0.13 to 0.66) for motor function recovery of the upper extremity. Main motor recovery outcome measure used was the Fugl-Meyer Assessment. In total, 14 studies, including 362 patients after ischemic and hemorrhagic stroke (cortical, subcortical, 121 females mean age 53.0+/− 5.8 mean time since stroke onset 15.7+/− 18.2 months) were included. A meta-regression was performed to evaluate the effects of covariates on the pooled effect-size. Standardized mean difference (SMD) with 95% confidence (95%CI) and 95% prediction interval (95%PI) were calculated. Data were meta-analysed using the random-effects model.
RCT or controlled clinical trials that included BCIT for improving motor and brain recovery in patients after a stroke were identified. MethodsĪ systematic literature search was performed in Medline, IEEE Xplore Digital Library, Cochrane library, and Embase in July 2018 and was repeated in March 2019. Numerous RCT investigated the effects of BCI training (BCIT) on recovery of motor and brain function in patients after stroke. Training with brain-computer interface (BCI) technology in the rehabilitation of patients after a stroke is rapidly developing.
