Multiple pulsed radiofrequency electrotherapy (RFET) can be used to awaken and stimulate the nerves after brachial plexus injury. Clinical studies have shown that the clinical application of pulsed radiofrequency electrotherapy is widespread and relatively mature, and can be categorized into low-frequency, medium-frequency and high-frequency pulsed electrotherapy. Generally, the most widely used is low-frequency electrotherapy, the frequency of which is not more than 1000Hz, and are low-voltage, adjustable, without obvious electrolysis, and basically harmless to the human body. This kind of therapy is suitable for the central nervous system or peripheral nervous system injury caused by limb movement, sensory disorders, sensory, motor nerves have a strong stimulation, pain relief, etc., can be used for the treatment of brachial plexus nerve injury. There are individual differences in treatment, if the individual is more sensitive to this electrical stimulation or discomfort, please follow the doctor’s advice to choose whether to discontinue.
