Self-Injurious Behavior Inhibiting System

Invented by Dr. Robert E. Fischell, Glen H. Fountain, and Charles M. Blackburn in 1984, the device is able to detect instances of head-directed SIB, and delivers an aversive electric shock contingent on its occurrence.

[2] The United States Food and Drug Administration (FDA) has concluded that aversive conditioning devices like the SIBIS pose an "unreasonable risk of harm" and are less effective than positive behavior support alone.

[3] The FDA states that such devices may cause both physical and psychological harm, including: depression, anxiety, worsening of self-injurious behavior, PTSD, burns, and pain.

Israel asked the manufacturer of the SIBIS, Human Technologies, to build a device that delivered stronger shocks, but they refused.

Israel then designed the Graduated Electronic Decelerator (GED), which delivered much more powerful shocks than the SIBIS that lasted ten times as long.
