A network meta-analysis of 72 randomized controlled trials covering 2,906 stroke patients found that noninvasive brain-computer interface (BCI) interventions significantly improve upper limb motor function and activities of daily living, with BCI combined with motor imagery and transcutaneous electrical acupoint stimulation ranking highest for motor recovery. The review, published in the Journal of Medical Internet Research on August 28, 2026, sorted 12 intervention types by paradigm, feedback device and adjunctive stimulation to produce relative rankings for clinical use. Evidence certainty was low to moderate, so the authors describe the findings as exploratory and call for higher-quality trials.
Researchers at Yonsei University in South Korea and the University of Toronto reviewed 64 studies covering 3,103 participants and found wireless EEG increasingly used in research on children with developmental disabilities, with brain-computer interfaces accounting for 28.1% of the included studies. BCI work favored low-channel, dry-electrode, consumer-grade devices, while biomarker-driven studies used higher channel counts and signal fidelity; reporting on data quality was thin, with 85.9% of studies giving no validation against wired EEG and 79.7% not specifying impedance thresholds. Published August 25, 2026 in the Journal of Medical Internet Research, it is the first scoping review to map wireless EEG use across a broad spectrum of developmental disabilities in children.
