Temporary or sub-threshold electrical stimulation to promote recovery of a damaged or injured nerve. Methods include promoting neuroregeneration of a nerve iatrogenically injured during a medical procedure performed on a target site of a patients body. Methods include placing an electrical lead in electrical communication with the injured or damaged nerve. Methods further include temporarily stimulating the nerve and/or applying sub-threshold stimulation to the nerve to promote neuroregeneration of the nerve. The nerve can be a peripheral nerve.
