This systematic review and meta-analysis evaluated the effects of brain-computer interface (BCI) training on lower-limb rehabilitation post-stroke, analyzing ten randomized controlled trials with 366 participants. BCI training significantly improved lower-limb motor function, with a mean difference of 2.38 in the Fugl-Meyer Assessment for Lower Extremity. The study highlights the potential of BCI in enhancing recovery, particularly in subacute stroke patients.
Key findings
- BCI training improved lower-limb motor function with a mean difference of 2.38 in the Fugl-Meyer Assessment.
- The improvement, while statistically significant, is below the Minimal Clinically Important Difference of 6 points.
- Subgroup analyses suggest a moderate total dose of 401-800 minutes may be optimal.
- Session durations of 20-40 minutes were associated with better outcomes.
Why it matters
Understanding the efficacy of BCI-based training can inform rehabilitation strategies for stroke patients, potentially enhancing recovery of motor function and improving quality of life. Clinicians may consider integrating BCI technology into rehabilitation protocols.
