the US Army tested it by generating the force using a pinch (EMP/Shockwave generator), and using shockpads (which test PSI) and the conclusion was if the explosion and shrapnel left the person unharmed, the shockwave would do the job, and they are now working on devices that could generate the same force and fit into a grenade sized device.
The shockwave from an explosion will often atomise a person. A lot of coffins being repatriated are weighed down with sand. It happened to a number of friends one day in '79.
The principle is that all waves have a frequency, and energy.
If you were far too brainy/nerdy, and you could calculate the energy required to break a molecular bond, and the frequency at which that energy is matched, you could cause the molecular bonds to break.
Within the human body, the principle is that the body operates by signals sent down the nerves from the brain, and these signals have a frequency attached to them that the brain operates on. In theory, if you directed the right frequency at the right place, you could interupt the signals from the brain.
The chances of finding the exact frequency that works on the exact part of the body that you want to control is really damned small.
Shockwave effect or exceedingly high db sounds is a lot more likely to have the desired effect, since inner ear's are rather sensitive.
