Experimental setup. (a): Subjects were instructed to sit in a chair with the hand resting on the handle. (b): At a random time, the latch was released, dropping the weight (20% of each subject’s hand strength), which applied sudden upward force to the handle. The subjects were instructed to stabilize the handle as soon as they noticed the perturbation.
