A 30 Kg object drop from 1 meter onto one's foot will unleash around 300 Joules. The heaviest barbell plate is usually 25 Kg. So 300 Joules is a lots of energy.

And I once heard a story, not sure how true it is, that someone put the defrib pads over the thigh and on activation the muscle contract so violently that breaks the bone.

I'm skeptical of this. for the Americans out here: 30 Kg is ~66lbs 1 meter is about 3 feet If an adult male (about 150 lbs) jumps off of a kitchen counter (about 3 feet) - each leg will absorb 75 lbs from 3 feet. I have done this many times and even my thin feet bones held the force. I'm pretty sure my thighs (our strongest bones) would be just fine.
