This systematic review and meta-analysis evaluated the effectiveness of motor imagery-based brain-computer interface (MI-BCI) training on upper limb motor function in post-stroke patients. Analyzing 24 studies with 846 participants, the results indicated significant improvements in isolated limb movement and fine motor control, with a standardized mean difference of 0.31 for the Fugl-Meyer Assessment and 0.45 for the Wolf Motor Function Test.
Key findings
- MI-BCI training improved isolated limb movement with a standardized mean difference of 0.31.
- Fine motor control also improved, showing a standardized mean difference of 0.45.
- The analysis included 24 studies with a total of 846 participants.
- No significant effects were found on complex functional activities or activities of daily living.
Why it matters
Understanding the potential benefits of MI-BCI training can inform rehabilitation strategies for post-stroke patients, particularly in enhancing specific motor functions. This knowledge may help clinicians tailor interventions to improve patient outcomes.
What to keep in mind
The evidence showed heterogeneity in control conditions across studies, limiting definitive conclusions about MI-BCI's superiority over traditional rehabilitation.
