What term describes the incapacitation mechanism for a dart-firing stun gun?

• A. Electro-muscular disruption (EMD)
• B. Nerve conduction injury
• C. Thermal burn
• D. Cardiac arrest

Answer: (A)

Electro-muscular disruption is the term that describes how a dart-firing stun gun causes incapacitation. The device delivers brief, high-voltage, low-current pulses that interfere with the body's normal nerve signals to skeletal muscles. This disruption makes muscles contract involuntarily and unsustainably, producing rapid, involuntary movements and a temporary loss of coordinated motor control. The effect is intended to be temporary and non-damaging, rather than causing nerve injury, burns, or cardiac arrest.

Nerve conduction injury implies lasting nerve damage or a conduction block, which is not the typical, immediate outcome of standard CEW use. A thermal burn would be a surface injury from heat rather than the primary incapacitation mechanism. Cardiac arrest is not the designed mechanism and is not a normal result of proper CEW deployment.
