Had this happen to me a few times today. During Ares Inferno, a trap went off and I was burned and lost control as if I'd been on the ground and standing in the fire. I don't know if it could happen with spike traps.
I had the same issue and it messed up the control. I went the opposite direction of the direction I was pressing. It was like it was a stun-locked hop.
Of course it ended up killing me.
