How about having wrists tied behind your back then being hoisted by said wrists so all your weight is placed on you (nearly dislocated shoulders)...and if that wasn't enough having electric currents applied to your feet? Or being tied to a hot radiator - or a freezer unit. Being kept in a tiny confined space - doubled up until you're in agony. Or being kept awake for days at a time until you don't know whether it's day or night, this week or next? Having your wife / sister / mother assaulted in an adjacent room so you can hear their screams but cannot see what is happening. Or electric currents applied to your genitals... There are many many witness testimonies whose injuries support their stories. And these 'techniques' aren't confined to adults - they are inflicted on minors too.
