“…In our proof-of concept study (Floreani et al, 2021), we found that participants achieved several of the basic skills of exploratory learners (Field and Livingstone, 2018), including demonstration of "awareness of motion, " "cause and effect, " "initiates motion" and "emotional response to motion." In the present study, findings indicate the participants would be classified as beginner "operational" learners (Gefen and Rosenberg, 2022).…”

“…In an initial proof-of-concept study we demonstrated a BCI-PMD prototype that could be controlled with a commercialgrade BCI system by children with quadriplegic cerebral palsy (Floreani et al, 2021). In the current study, we extend this line of investigation to formally assess the feasibility of such a system for this population to explore independent movement.…”

“…Participants had a range of previous BCI experience (1 month to 5 years), based on their time within our clinical BCI program. 5 participants had one prior exposure using BCI to drive a PMD when participating in our proof-of-concept study (Floreani et al, 2021). 2 participants (P4 and P6) had previous power mobility experience using alternative access technologies (i.e., switches and/or joysticks), but struggled to use them effectively for functional driving.…”

IntroductionChildren with severe physical disabilities are denied their fundamental right to move, restricting their development, independence, and participation in life. Brain-computer interfaces (BCIs) could enable children with complex physical needs to access power mobility (PM) devices, which could help them move safely and independently. BCIs have been studied for PM control for adults but remain unexamined in children. In this study, we explored the feasibility of BCI-enabled PM control for children with severe physical disabilities, assessing BCI performance, standard PM skills and tolerability of BCI.Materials and methodsPatient-oriented pilot trial. Eight children with quadriplegic cerebral palsy attended two sessions where they used a simple, commercial-grade BCI system to activate a PM trainer device. Performance was assessed through controlled activation trials (holding the PM device still or activating it upon verbal and visual cueing), and basic PM skills (driving time, number of activations, stopping) were assessed through distance trials. Setup and calibration times, headset tolerability, workload, and patient/caregiver experience were also evaluated.ResultsAll participants completed the study with favorable tolerability and no serious adverse events or technological challenges. Average control accuracy was 78.3 ± 12.1%, participants were more reliably able to activate (95.7 ± 11.3%) the device than hold still (62.1 ± 23.7%). Positive trends were observed between performance and prior BCI experience and age. Participants were able to drive the PM device continuously an average of 1.5 meters for 3.0 s. They were able to stop at a target 53.1 ± 23.3% of the time, with significant variability. Participants tolerated the headset well, experienced mild-to-moderate workload and setup/calibration times were found to be practical. Participants were proud of their performance and both participants and families were eager to participate in future power mobility sessions.DiscussionBCI-enabled PM access appears feasible in disabled children based on evaluations of performance, tolerability, workload, and setup/calibration. Performance was comparable to existing pediatric BCI literature and surpasses established cut-off thresholds (70%) of “effective” BCI use. Participants exhibited PM skills that would categorize them as “emerging operational learners.” Continued exploration of BCI-enabled PM for children with severe physical disabilities is justified.
