Creating an engaging brain computer interface, electrical stimulation therapy for children with hemiparesis: a pilot study.
Article in Journal of neuroengineering and rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPerinatal stroke can lead to lifelong physical disabilities, where even small improvements in motor function can increase quality of life. Rapid brain development in children provides an opportunity to harness brain plasticity. Current therapies are minimally effective due in part to the boring, unengaging procedures required to achieve adequate repetitions required for therapeutic benefit. The combination of brain computer interface and functional electrical stimulation (BCI-FES) may be effective for adults with stroke-induced hemiparesis and appears feasible in children. We designed a novel BCI-FES system that uses social media to engage youth.
methodsThe project was informed through engagement with youth patient partners with lived experience. Participants were fitted with a 16channel EEG gel headset. BCI training consisted of 20 trials of attempted target movement. Successful classification was paired with FES of the target movement and allowed the participant to swipe to watch the next video as desired. Youth with perinatal stroke and hemiparesis were then recruited to trial the system. Outcomes included training accuracy, BCI performance (Cohen's kappa), box and blocks, and qualitative interviews to characterize usability and patient experience.
resultsTwelve participants (aged 10–23 years) completed three sessions. No adverse events occurred; fatigue was minimal and varied across sessions. System performance varied but most sessions had moderate or better agreement. Average repetitions for all sessions were 167 reps/hour [SD = 55.2 range = 65–283 reps/hour] with FES and 247 reps/hour [SD = 74.9 range = 105–379 reps/hour] with and without FES (attempts and training). Motor outcomes were variable but improved for some. Qualitative feedback suggested higher motivation and enjoyment compared with traditional therapies but also identified frustrations surrounding technical challenges and equipment comfort.
conclusionInformed by users, simple EEG-based BCI can be integrated with FES and social media to enhance upper extremity rehabilitation in youth with hemiparesis. This pilot trial will inform the design of future clinical trials to evaluate efficacy.
