Electrical stimulation of denervated muscle will:

• A. Maintains part of its contractility and nutrition
• B. Does prevent atrophy
• C. Will produce an alternating contraction
• D. Maintains circulation

Answer: (A)

Electrical stimulation of denervated muscle works by directly activating the muscle fibers themselves because the nerve supply is lost. By delivering appropriate long-duration pulses, the muscle can still contract, and those contractions help keep the muscle tissue metabolically active and structurally supported. This means you preserve part of the muscle’s contractile apparatus and its trophic health, even though full, normal function isn’t restored. It won’t completely stop wasting over time, and the contractions produced differ from normal innervated contractions; they’re typically slower and rely on direct muscle fiber activation rather than a coordinated nerve-driven rhythm. So the best summary is that stimulation maintains part of the muscle’s contractility and nutrition.
