[Principles of electric stimulation in flaccid paralysis]

Electrostimulation must be selective and sparing. Selectivity is obtained establishing which denervated muscles are responsible for loss of a given function, choosing a proper size of the stimulating electrode and its point of application, and testing the muscle bioelectrically. Sparing electrostimulation includes the application of current of appropriate parameters, that is: impulse duration, current intensity, frequency of impulses and duration of procedure. The results obtained by this method assessed according the Lovett's scoring system were very good and good in moderately advanced paresis, but unsatisfactory in severe paralysis.
