Recent studies demonstrated that electrical stimulation applied directly to an injured peripheral nerve resulted in marked improvement of nerve regeneration. Preliminary data suggesting that electrical nerve stimulation could possibly enhance nerve regeneration has in fact been known for some time. Accelerated rate of regeneration was found in animals that received electrical stimulation for as little as 1 hour. Furthermore, preferential growth of the regenerating sensory axons into the appropriate nerve branch was also accelerated with electrical stimulation.
