Hi everyone!

I have some doubts about Functional electrical stimulation (FES). FES can elicit muscle contractions to persons with neuromuscular disorders (such dorsiflexion/plantarflexion in stroke subjects). What I wanted to know is can this "production" of movement be achieved with a Transcutaneous Electrical Nerve Stimulation (TENS) signal or an Electrical Muscle Stimulation (EMS) signal? Could both do it?
Is the difference between EMS and TENS simply where you put the electrodes (ie the area to be stimulated), apart from different electrical signals? So if I put an electrode (-) over a nerve and the other (+) in the motor point of the muscle I have TENS? and if I place both electrodes over the muscle directly (in the muscle's origin and insertion for e.g.) I will have EMS?

Thank you for your replies.
