This is a unique example of an electroconvulsive therapy device, likely of Swiss origin.

During the pioneering years of psychological discoveries by Sigmund Freud and others, when extensive experimentation was conducted with chemicals and electricity, these devices were tested as treatments for mental disorders—particularly severe depression, schizophrenia, and manic episodes. They utilized electrical currents to induce intentional convulsions, or controlled epileptic seizures in the patient's brain. The devices were simple, operating on alternating current with varying voltage and duration. The goal was to influence neural activity in the brain and achieve therapeutic effects.

The occasional success of such treatments contributed to the widely accepted notion that mental illnesses have a biological basis.

Although early devices were not always entirely safe or precise, they nonetheless laid the foundation for modern electroconvulsive therapy, which is now carried out under strict safety standards.

This particular device is in excellent aesthetic condition, complete with all its original accessories.
