The Role of Functional Electrical Stimulation in Brachial Plexus Injury Repair

Brachial plexus injury (BPI) is a type of peripheral nerve injury, which is mainly manifested as upper limb sensory and motor dysfunction. Although the injury will not endanger life, it can cause serious functional loss and high disability rate, and eventually lead to patients unable to live normally. At present, the treatment methods for BPI mainly include conservative treatment, such as limb massage, exercise, drug therapy, autonomous movement and strength training; In clinic, nerve repair, nerve transplantation and muscle transfer can also be used. Although surgical treatment can better restore the function of injured brachial plexus, there is a certain risk, so it is not the first choice of treatment. As a mature electrical stimulation method, functional electrical stimulation (FES) can play a good role in promoting injured nerve regeneration and preventing skeletal muscle denervation atrophy, so it can be widely used in the treatment and functional recovery of BPI. This article will review the research progress of FES in the treatment of BPI.
