Neuromuscular Incapacitation (NMI) 
Neuromuscular Incapacitation (NMI) 

The human nervous system communicates with simple electrical impulses. The command center (brain and spinal cord) processes information and makes decisions. The peripheral nervous system includes the sensory and motor nerves. The sensory nerves carry information from the body to the brain (temperature, touch, etc.). The motor nerves carry commands from the brain to the muscles to control movement.

TASER technology uses similar electrical impulses to cause stimulation of the sensory and motor nerves. Neuromuscular Incapacitation (NMI) occurs when a device is able to cause involuntary stimulation of both the sensory nerves and the motor nerves. It is not dependent on pain and is effective on subjects with a high level of pain tolerance.

Previous generations of stun guns could primarily affect the sensory nerves only, resulting in pain compliance. A subject with a very high tolerance to pain (e.g., a drug abuser, or a trained, focused fighter) might be able to fight through the pain of a traditional stun gun.

COMMON EFFECTS OF NMI

The use of TASER technology causes incapacitation and strong muscle contractions making secondary injuries a possibility. These potential injuries include but are not limited to: cuts, bruises, impact injuries, and abrasions caused by falling, and strain-related injuries from strong muscle contractions such as muscle or tendon tears, or stress fractures. These injuries are secondary in nature and not directly attributable to the electric output of the TASER device, but are possible consequences of the strong muscle contractions the TASER device induces to produce incapacitation. Some of the effects may include:

  • Subject can fall immediately to the ground and be unable to catch him/herself.
  • Subjects located in the water may drown if their ability to move is restricted.
  • Subject may yell or scream.
  • Involuntary strong muscle contractions.
  • Subject may freeze in place with legs locked.
  • Subject may feel dazed for several seconds/minutes.
  • Potential vertigo.
  • Temporary tingling sensation.
  • May experience critical stress amnesia (may not remember any pain).
