The stun gun is designed to key into the nervous system. It dumps its energy into the muscles at a high pulse frequency that makes the muscles work very rapidly. This rapid work cycle depletes blood sugar by converting it into lactic acid all in just seconds. The resulting energy loss makes it difficult to move and function. This causes disorientation and loss of balance, leaving the attacker in a passive and confused condition for several minutes; there is no significant effect on the heart and other organs.
As a general rule, a 1/4 second contact will repel and startle the attacker, giving intense pain and muscle contraction. One to two seconds will cause intense pain, muscle spasms and a dazed mental state, this may drop the attacker to the ground. Over three seconds will cause intense pain, loss of balance, loss of muscle control, mental confusion and disorientation. Generally, any charge over three seconds will cause the aggressor to fall to the ground. The aggressor will be unable to recover for several minutes and effects may last for up to fifteen minutes.
