A quasi-experimental study on the effect of electrical aversion treatment on imposed mechanical restraint for severe self-injurious behavior.

The team followed the adults with severe intellectual disability. All hurt themselves so badly that staff had to tie on arm splints or jackets every day.

Six adults got a three-year program of brief electric skin shock when they hit or bit themselves. Six matched adults kept the restraints but got no shock. Staff counted how often the ties were needed.

By year three, the shock group wore restraints only half as often as the no-shock group. Some stopped needing the splints at all.

The bites and bruises on their arms also dropped sharply. Staff wrote that the adults looked calmer and easier to dress.

Lovaas et al. (1969) first showed that a quick shock could turn self-injury on and off in three kids. Pilgrim et al. (2000) later proved the same idea works in real-world wards over years.

Corrigan et al. (1998) tried a gentler buzz called TENS. It helped for a day, then wore off. The new data say a true aversive shock lasts, but TENS is too weak for life-long safety.

Rosenthal et al. (1980) warned that arm splints cut social play. C et al. cut the splints instead, trading a brief shock for more freedom and interaction.

You now have solid evidence that contingent electric shock can free adults from daily mechanical restraints. Yet most states, funders, and ethics boards bar or limit its use. When lethal self-injury meets every other failure, document the risks, gain full consent, and seek an ethics panel before considering this option. For most cases, lean on today’s safer tools—functional analysis, reinforcement of safer responses, and protective equipment—while you track data just as carefully as these authors did.
