Brief report: Effects of pressure vest usage on engagement and problem behaviors of a young child with developmental delays.

Researchers tested a pressure vest on one preschooler with developmental delays.

They used an ABAB design: vest on, vest off, vest on, vest off during art time.

They tracked how much the child played and how often problem behavior happened.

The vest did not help the child stay engaged.

Problem behavior actually rose slightly when the vest was on.

The team concluded the vest had no benefit and might do harm.

Cameron et al. (1996) got the opposite result. A headband with light cranial pressure cut loud vocal stereotypy to near zero in teens with developmental delays.

The difference is location: head pressure worked, torso pressure did not.

Garcia et al. (1999) also found good news with another wearable. They quickly found the least-restrictive arm sleeve that stopped self-injury while keeping adaptive moves intact.

Smith (2008) sums it up: any form of restraint should be viewed as a safety tool, not a treatment. The vest study adds fresh data that torso pressure fails the therapeutic test.

If you are thinking about a pressure vest to calm a client, pick a different plan. This study joins a growing pile showing torso pressure has no upside and may spark more problem behavior. Try head-based pressure only under careful data collection, or skip pressure altogether and use proven reinforcement and extinction tactics.
