Who developed FES for foot drop?

Question

electro stimulation

Answer 1

The theory goes back to the 19th century, but one of the earliest FES systems for correcting foot drop was developed by W.T. Liberson and colleagues in Archives of Physical Medicine and Rehabilitation in 1961. Their approach was to place a foot switch in the shoeunder the heel of a stroke patient who could not flex the ankle. During walking, removal of pressure from the switch at the end of the stance phase triggered stimulation of the common peroneal (CP) nerve to flex the ankle and prevent the foot from dropping or dragging on the ground during the swing phase.
