Is electrical stimulation effective for nerve injury?

Electrical stimulation is generally effective for nerve injuries.

Electrical stimulation is a form of physical therapy and is commonly used and effective in treating nerve damage. Treatment typically begins 2–3 weeks after the onset of nerve injury. Parameters such as pulse width, interval, and stimulation intensity should be adjusted according to the severity of the nerve damage. This allows the affected nerves and muscles to respond to electrical stimulation without causing excessive contraction or pain in healthy nerves and muscles. Electrical stimulation provides appropriate activation to the affected muscles, inducing rhythmic contraction and relaxation, which helps restore nerve excitability and conduction function and promotes nerve regeneration. Additionally, electrical stimulation can prevent thickening of muscle connective tissue, reduce the risk of muscle spasms and fibrosis, and help avoid muscle contractures and deformities.

After a nerve injury, patients should ensure adequate rest in daily life and avoid excessive fatigue. They should also maintain a light diet and avoid spicy foods such as chili peppers and ginger, which may interfere with recovery.
