Communication Brain-Computer Interfaces (cBCIs) use neural signals to control a computer and are of interest as a communication tool for people with motor and speech impairment. Whereas the majority of cBCI research focuses on adults, the technology may also benefit children and adolescents with communication impairments, for example as a result of cerebral palsy (CP). Here we aimed to create a solid basis for the user centered design of cBCIs for children and adolescents with CP and complex communication needs by investigating the perspectives of their parents/caregivers and health care professionals on communication and cBCIs. We conducted an online survey on 1) current communication problems and usability of used aids, 2) interest in cBCIs, and 3) preference for specific types of cBCIs. A total of 19 parents/caregivers and 36 health care professionals who live(d) or work(ed) directly with children and adolescents (8-25 years old) with quadriplegic CP participated. Both groups of respondents indicated that, of 12 potential communication-limiting factors, motor impairment occurred the most frequently and also had the greatest impact on communication. The currently used communication aids included mainly no/low-tech aids (e.g., letter card) and high-tech aids (e.g., tablet or computer). Mid-tech aids (e.g., systems with static displays) were less frequently used. The majority of health care professionals and parents/caregivers reported an interest in cBCIs for children and adolescents with severe CP, with a slight preference for implanted electrodes over non-implanted ones, and no preference for either of the two proposed mental BCI control strategies (visual stimuli and imagined/attempted movement). These results indicate that cBCIs should be considered for a subpopulation of children and adolescents with severe CP, and that in the development of cBCIs for this group both P300 and sensorimotor rhythms, as well as the use of implanted electrodes, should be considered.
