Whether motor nerve damage can be recovered is related to the time and severity of the injury. When the motor nerve injury is short and the injury is mild, it can generally be recovered through timely treatment; when the damage is longer and the injury is more severe, it generally cannot be recovered. Motor nerve injury is relatively mild, there may only be edema and contusion of the nerve, while the injury is relatively short, then through nutritional drug treatment, with the later rehabilitation training and hyperbaric oxygen therapy, generally can be recovered. If the motor nerve injury is simply caused by nerve entrapment syndrome or increased blood glucose, the symptoms can be relieved by reducing the edema of the nerve root by lowering the sugar and dehydration, together with neurotrophic treatment. If the motor nerve injury is very serious and complete nerve necrosis occurs, it is usually not recoverable and often leaves some sequelae. For example, if the motor nerve is severely damaged due to trauma, the damage cannot be recovered because the nerve cells are not regenerated. At this time, family members should pay attention to communicate with the patient to avoid a series of negative emotions, and pay attention to take the patient to outdoor activities to divert the patient’s attention from the disease.
