This report describes NeuroPage, a simple and portable paging system, developed in California by the engineer father of a son with head injury working together with a neuropsychologist. Using an ABA single case experimental design, the efficacy of NeuroPage was evaluated with 15 neurologically impaired subjects all of whom had significant everyday memory problems because of organic memory impairment or because of problems with planning and organisation consequent on frontal lobe damage. Data were analysed with an odds ratio test which takes into account different underlying success rates for each target and calculates an average improvement factor. This test showed a significant improvement between the baseline and the treatment phases for each subject (P<0.05).
