The subject's ability to move may be affected how?

• A. Easily Command muscles to move
• B. No effect on movement
• C. Causes involuntary movement
• D. Hard time telling their muscles to move

Answer: (D)

This item tests how electrical incapacitation from a stun device affects motor control. CEWs disrupt normal nerve signaling to muscles, making voluntary movement harder to initiate and coordinate. That means the subject may be unable to tell their muscles to move in a controlled way, or may move awkwardly or with delay. The described effect—having a hard time telling their muscles to move—best reflects the temporary impairment of voluntary motor control after exposure.

The other possibilities don’t fit as well: easily commanding muscles to move would imply improved control, which isn’t the typical outcome. No effect on movement ignores the known impact on motor function. While CEWs can cause involuntary contractions, the question focuses on voluntary movement control, and the emphasis on difficulty initiating movement aligns with that effect.
