In 1995, in a case relating to hazardous seating systems which resulted in asphyxiation in child users, a plaintiff reserved funding which enabled Peter, in conjunction with fellow RESNA scholars, to publish a paper bringing awareness and encouraging standards to prevent the strangulation of children in wheelchairs.
