When a person thinks about making a fist in their brain, there are many electrical connection (nerves)from your brain to the muscles in your hand that are activated. When a person touches high voltage electricity the electricity activates the nerves and then the muscles in your hand and this activation is much stronger than the message sent from your brain, so your muscles cannot relax.
