Children with severe hemiparesis have limited rehabilitation options. Brain computer interface- activated functional electrical stimulation (BCI-FES) of target muscles may enhance upper extremity function in hemiparetic adults. We conducted a pilot clinical trial to assess the safety and feasibility of BCI-FES in children with hemiparetic CP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Thirteen participants (mean age = 12.2 years, 31% female) were recruited from a population-based cohort. Inclusion criteria were: (1) MRI-confirmed PS, (2) disabling hemiparetic CP, (3) age 6\u201318 years, (4) informed consent\/assent. Those with neurological comorbidities or unstable epilepsy were excluded. Participants attended two BCI sessions: training and rehabilitation. They wore an EEG-BCI headset and two forearm extensor stimulation electrodes. Participants\u2019 imagination of wrist extension was classified on EEG, after which muscle stimulation and visual feedback were provided when the correct visualization was detected.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>No serious adverse events or dropouts occurred. The most common complaints were mild headache, headset discomfort and muscle fatigue. Children ranked the experience as comparable to a long car ride and none reported as unpleasant. Sessions lasted a mean of 87 min with 33 min of stimulation delivered. Mean classification accuracies were (<jats:italic>M<\/jats:italic> = 78.78%, SD = 9.97) for training and (<jats:italic>M<\/jats:italic> = 73.48, SD = 12.41) for rehabilitation. Mean Cohen\u2019s Kappa across rehabilitation trials was <jats:italic>M<\/jats:italic> = 0.43, SD = 0.29, range = 0.019\u20131.00, suggesting BCI competency.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Brain computer interface-FES was well -tolerated and feasible in children with hemiparesis.
