Peripheral nerves are the nerves that branch out from the spinal cord. These nerves can get injured due to a variety of reasons i.e. trauma, diabetes, autoimmunity, toxins, nutrient deficiencies, etc. Oftentimes these nerves need proper stimulation in order to recover following these triggers. Our nerves are electric. As a result if you stimulate them with the right types of electrical current they can help them repair and grow.
