Persons with multiple disabilities exercise adaptive response schemes with the help of technology-based programs: three single-case studies.

Three adults with severe multiple disabilities tried a tech setup. Each wore a small sensor on the head, arm, or hand.

When they moved the right way, a computer gave 8 s of their favorite song or video. The team counted how many correct moves happened each day.

All three people quickly doubled or tripled their target moves. Gains showed up in the first week and stayed high.

One woman raised head lifts from 4 to 18 per session. A man lifted his arm from 6 to 25 times. The third person touched a pad from 3 to 20 times.

Lancioni et al. (2009) used the same microswitch gear for choice-making, not exercise. The 2012 paper keeps the tech but swaps the goal: move first, then get music.

Carr et al. (2003) taught requests with several switches. The new study uses only one switch per person and links it to body exercise, showing the tool can wear two hats.

McGonigle et al. (2014) taught girls with Rett syndrome to press a voice switch to ask for things. Both papers prove a single switch press can open big doors, whether the output is speech or music.

If a client has little movement, a sensor plus 8 s of Taylor Swift or Peppa Pig can turn that tiny move into a useful response. You can start with any microswitch you already own, set the reward for 3-5 s at first, and shape the topographies you need for future communication or mobility.
