Using a Taser to control agitated suspects in police custody is standard operating procedure for many law enforcement agencies. In some circles, however, the idea that using a Taser could lead to a suspects death has caused controversy.
Now, the final results of a study conducted by emergency medicine physicians at the University of California, San Diego (UCSD) Medical Center showed no lasting effects of the Taser on healthy test subjects.
"Evaluating in-custody deaths following use of a Taser is a process that requires looking at the totality of the event. It is like putting a puzzle together. The data from this study helped shape another piece of the puzzle by looking at the physiological effects of a single Taser activation in human subjects," said study director Gary Vilke, M.D., professor of clinical medicine and director of Clinical Research for Emergency Medicine at UC San Diego. Vilke presented his findings at the 2007 Society for Academic Emergency Medicine (SAEM) Annual Meeting, May 16-19, 2007, Chicago, IL.
Taser subdues a person by delivering an electrical current that interferes with the bodys neuromuscular system, temporarily incapacitating the recipient.
"I have been Tazed," said Vilke. "The experience is painful while its happening but afterward, you only feel sore, like you might after a tough workout. Our goal was to find out how, in the absence of alcohol, drugs or other stimulants, humans are affected physiologically."
Vilke monitored the reactions of 32 healthy volunteers from the San Diego County Sheriffs Department who agreed to receive a single, five-second exposure from a Taser X26, the model reportedly used by more than 30 percent of police agencies in the United States. The standard issue law enforcement Taser is set to administer an electric shock in five-second intervals.
