Promoting adaptive behaviors by two girls with Rett syndrome through a microswitch-based program

• A microswitch-based program was used to enhance adaptive behaviors in two girls with RS.
• A new combination of microswitches promoting constructive engagement was assessed.
• Object manipulation and ambulation responses improved during intervention phases.
• The program had positive effects on mood and stereotyped behaviors in both participants.
• The assistive technology system was suitable and affordable for girls with Rett syndrome.

We assessed a microswitch-based program to improve self-determination to access to preferred stimuli and to foster locomotor behavior by two girls with Rett syndrome and multiple disabilities. To enhance the first behavior (access to preferred stimuli) a wobble microswitch (sensitive touch sensor) was used while for the second behavior (step responses) optic sensors were applied. A second aim of the study was to monitor indices of happiness as consequence of the use of assistive technology. Finally, a third objective of the study was the reduction of hand washing and body rocking related stereotypies. The study was carried out according to a multiple probe design across behaviors for both participants, where the two behaviors were first learned independently, then combined together. Results showed an increasing of performance and of indices of happiness and a decreasing of stereotyped behaviors for both participants during intervention phases. Practical, psychological and clinical implications of the findings are discussed.
