Background:

Denervating injuries lead to flaccid paralysis and significant muscle atrophy.
Restoring muscle function after nerve damage is a critical clinical challenge.

Purpose of the Study:

To review the potential of electrical stimulation for functional restoration of denervated muscles.
To focus on the fundamental scientific issues underlying this therapeutic approach.

Main Methods:

Literature review of studies on electrical stimulation and denervated muscle.
Analysis of basic science principles relevant to muscle electrophysiology and regeneration.

Main Results:

Electrical stimulation shows promise for counteracting muscle atrophy and potentially restoring function.
