Promoting mouth drying to reduce the effects of drooling in a woman with multiple disabilities: a new evaluation of microswitch-programme conditions

Generalization and maintenance of a self-management program for drooling in children with neurodevelopmental disabilities: A second case series

In this case series (n = 10) with a non-concurrent multiple baseline design, a self-management program was shown to be effective during inpatient training in eight participants with oral-motor problems and normal intelligence or mild intellectual disabilities. They were taught to perform a self-management routine and to remain dry for increasing time intervals. In addition, the program provided differential (self-) reinforcement of swallowing, controlling and wiping behavior, explicit formulation of motivational factors, instruction and feedback for parents and teachers, and continued practice after discharge. Generalization of the initial effect to the school setting was demonstrated in seven participants. Follow-up assessments demonstrated maintenance of positive results in four children up to 24 weeks, and for two other participants until 6 weeks after discharge. These results appeared to be relevant to parents and teachers. Teaching parents and teachers to implement the procedure enables them to support the child without professional supervision in the case of relapse.

Persons with multiple disabilities increase adaptive responding and control inadequate posture or behavior through programs based on microswitch-cluster technology

Study I used typical microswitch-cluster programs to promote adaptive responding (i.e., object manipulation) and reduce inappropriate head or head-trunk forward leaning with a boy and a woman with multiple disabilities. Optic, tilt, and vibration microswitches were used to record their adaptive responses while optic and tilt microswitches monitored their posture. The study included an ABB(1)AB(1) sequence, in which A represented baseline phases, B represented an intervention phase in which adaptive responses were always followed by preferred stimulation, and B(1) represented intervention phases in which the adaptive responses led to preferred stimulation only if the inappropriate posture was absent. Study II assessed a non-typical, new microswitch-cluster program to promote two adaptive responses (i.e., mouth cleaning to reduce drooling effects and object assembling) with a man with multiple disabilities. Initially, the man received preferred stimulation for each cleaning response. Then, he received stimulation only if mouth cleaning was preceded by object assembling. The results of Study I showed that both participants had large increases in adaptive responding and a drastic reduction in inappropriate posture during the B(1) phases and a 2-week post-intervention check. The results of Study II showed that the man learned to control drooling effects through mouth cleaning and used object assembling to extend constructive engagement and interspace cleaning responses functionally. The practical implications of the findings are discussed.
