How should functional electrical stimulation be used in neuropraxia?

• A. It does not matter but does not cause damage
• B. It accelerates nerve regeneration
• C. It damages muscle tissue
• D. It can permanently worsen nerve function

Answer: (A)

In neuropraxia the nerve conduction is temporarily blocked but the axon remains intact, so recovery happens as the myelin is repaired over days to weeks rather than by new axon growth. Functional electrical stimulation is used mainly to keep the affected muscles active, prevent disuse atrophy, and maintain range of motion while the nerve heals. It does not speed up the nerve’s healing process, but it is safe and does not cause harm when used with proper settings. So the best outcome is that FES does not alter the recovery rate, and it does not cause damage. The other options imply nerve healing is accelerated or that muscle tissue is damaged or nerve function worsens, which aren’t supported by standard use of FES in this scenario.
