Conversely, cable Regulate is quick and physical, and through that gives a specific diploma of direct pressure feed-back that myoelectric control doesn't.

For instance, about two,200 yrs in the past, the Roman normal Marcus Sergius Silus misplaced his appropriate hand in the course of the 2nd Punic War.
