This study was aimed at assessing a smartphone-based intervention to help 11 individuals with moderate Alzheimer's disease and ambulation problems to manage goal-directed, walker-assisted ambulation and object use (i.e., to reach specific destinations and put away objects at those destinations independently). The study was carried out according to a non-concurrent multiple baseline design across participants. Two measures were recorded, that is, the number of target responses performed correctly (with each target response consisting of reaching a destination and putting away an object), and the number of observation intervals with indices of enjoyment/appreciation (e.g., smiles and positive comments). During baseline, the participants were provided with a walker and three objects that were to be transported to and put away at specific destinations. During the intervention, the participants also had the smartphone-based technology that provided them with instructions about the destinations and objects, praise, and preferred stimulation. During baseline, the mean frequency of correct target responses was virtually zero. The mean frequency of intervals with indices of enjoyment/appreciation ranged from zero to close to one. During the intervention, the mean frequencies for the two measures were slightly below three and just over three, respectively. The maximum frequencies possible were three and four, respectively. A smartphone-based intervention may be suitable to foster goal-directed, walker-assisted ambulation and object use as well as enjoyment/appreciation in participants like those involved in this study.IMPLICATIONS FOR REHABILITATIONA smartphone-based intervention may be used to promote goal-directed, walker-assisted ambulation and object use as well as indices of enjoyment/appreciation in persons with moderate Alzheimer disease.The technology for such intervention might involve (a) a smartphone with Android operating system, light sensor, Bluetooth v4.0, and MacroDroid, (b) Bluetooth headphones or earpieces, and (c) battery-powered light sources.The technology may provide the participants with instructions about the destinations to reach and the objects to put away at those destinations, and with praise and brief periods of preferred stimulation at the target destinations.The technology may be considered easy to access, friendly for the participants, and suitable for use by staff within daily contexts.
