Upgraded technology for contingent stimulation of mouth wiping by two persons with drooling and profound developmental disabilities

Many persons with developmental and physical disabilities experience drooling (i.e., loss of saliva from the mouth). Technology was recently developed to help two of these persons reduce the negative effects of drooling by increasing mouth-wiping responses. This study upgraded our initial approach and tested it with the two persons who we previously treated. Upgrading ensured that all technology components, including the stimulation sources, were on the participant’s body and that stimulation for mouth wiping caused no (or limited) environmental disturbance. We also conducted a social validation assessment of the new technology and its effects, employing university students as social raters. Evidence showed that the participants used the upgraded technology successfully in settings attended by varieties of other persons. The university students involved in the social validation viewed the use of the technology as enjoyable, beneficial, and environmentally acceptable, and they largely supported it.
