The parrilla was commonly used at Villa Grimaldi, a prison complex maintained by Dirección de Inteligencia Nacional, a part of the Pinochet regime. In the 1970s, during the Dirty War, the parrilla was used in Argentina. Francisco Tenório Júnior (known as Tenorinho), a Brazilian piano player, was subjected to the parrilla during the military dictatorship in Brazil.Advocates for the mentally ill and some psychiatrists such as Thomas Szasz have asserted that electroconvulsive therapy (ECT) is torture when used without a bona fide medical benefit against recalcitrant or non-responsive patients.The Judge Rotenberg Center in Canton, Massachusetts has been condemned for torture by the United Nations special rapporteur on torture for its use of electric shocks as punishment as part of its behavior modification program.Japanese serial killer Futoshi Matsunaga used electric shocks to control his victims. Capital punishment
Electric shock delivered by an electric chair is sometimes used as an official means of capital punishment in the United States, although its use has become rare from the 1990s onward due to the adoption of lethal injection. Although some original proponents of the electric chair considered it to be a more humane execution method than hanging, shooting, poison gassing, etc., it has now generally been replaced by lethal injections in states that practice capital punishment. Modern reporting has claimed that it sometimes takes several shocks to be lethal, and that the condemned person may actually catch fire before death. Other than in parts of the United States, only the Philippines reportedly has used this method, from 1926 to 1976.
Symptoms may include:
Depression, including feelings of low self-esteem and guilt
Anxiety spectrum disorders, including posttraumatic stress disorder and fear of electricity
Moodiness, including a lower threshold for frustration and "losing ones temper"
Memory loss, decreased attention span, and difficulty learning

Arc-flash hazards
OSHA found that up to 80 percent of its electrical injuries involve thermal burns due to arcing faults. The arc flash in an electrical fault produces the same type of light radiation from which electric welders protect themselves using face shields with dark glass, heavy leather gloves, and full-coverage clothing. The heat produced may cause severe burns, especially on unprotected flesh. The arc blast produced by vaporizing metallic components can break bones and damage internal organs. The degree of hazard present at a particular location can be determined by a detailed analysis of the electrical system, and appropriate protection worn if the electrical work must be performed with the electricity on. Pathophysiology
The minimum current a human can feel depends on the current type (AC or DC) as well as frequency for AC. A person can sense electrical current as low as 1 mA (rms) for 60 Hz AC and as low as 5 mA for DC. At around 10 mA, DC current passing through the arm of a 68-kilogram (150 lb) human can cause powerful muscle contractions; the victim is unable to voluntarily control muscles and cannot release an electrified object. This is known as the "let go threshold" and is a criterion for shock hazard in electrical regulations.
