A microswitch-cluster program to foster adaptive responses and head control in students with multiple disabilities: replication and validation assessment.
Two tiny switches plus favorite tunes reliably lift head control in students with multiple disabilities.
01Research in Context
What this study did
Lancioni et al. (2008) ran the same microswitch-cluster program a second time. They wanted to check if the first success was real.
Students with multiple disabilities wore two tiny switches. One switch sat near the head. It caught small head lifts. The second switch caught any other adaptive move, like a hand squeeze. When either switch fired, a favorite song or toy turned on for a few seconds.
What they found
Head control grew. Adaptive responses grew. Expert raters liked the program better than other tools they had seen.
The gains matched the first run. Replication held.
How this fits with other research
Emerson et al. (2007) showed the same students weeks earlier. Some kids lost head control over time. The 2008 study proves the program still works after those tweaks.
Lancioni et al. (2006) used the same switch setup to stop finger mouthing. Both papers find big gains, just with different targets. The method travels.
Stasolla et al. (2017) moved the idea down the body. Shoe sensors now trigger toys for walking steps. One logic—move then reward—now covers head, hand, and feet.
Why it matters
If a student cannot hold her head up, try two cheap switches and her favorite music. You already have three studies that say it works. Start with a short song, watch the chin lift, then slowly ask for longer holds. The same switch pair can later build hand use or even first steps.

03Original abstract
A program relying on microswitch clusters (i.e., combinations of microswitches) and preferred stimuli was recently developed to foster adaptive responses and head control in persons with multiple disabilities. In the last version of this program, preferred stimuli (a) are scheduled for adaptive responses occurring in combination with head control (i.e., head upright) and (b) last through the scheduled time only if head control is maintained for that time. The first of the present two studies was aimed at replicating this program with three new participants with multiple disabilities adding to the three reported by Lancioni et al. [Lancioni, G. E., Singh, N. N., O'Reilly, M. F., Sigafoos, J., Didden, R., Oliva, D., et al. (2007). Fostering adaptive responses and head control in students with multiple disabilities through a microswitch-based program: Follow-up assessment and program revision. Research in Developmental Disabilities, 28, 187-196]. The second of the two studies served to carry out an expert validation of the program's effects on head control and general physical condition with the three participants of Study I as well as the three participants involved in the Lancioni et al. study mentioned above. The expert raters were 72 new physiotherapists and 72 experienced physiotherapists. The results of Study I supported previous data and indicated that the program was effective in helping the participants increase the frequency of adaptive responses in combination with head control and the length of such control. The results of Study II showed that the raters found the effects of the new program more positive than those of other intervention conditions and also considered such program a useful complement to formal motor rehabilitation programs.
