Whether motor nerve damage can be recovered or not is related to the time and severity of the injury, etc. When the time of motor nerve damage is shorter and the injury is milder, it can usually be recovered through timely treatment; when the time of damage is longer and the injury is more severe, it cannot be recovered in general. When the motor nerve injury is relatively mild, there may only be edema and contusion of the nerve, and the time of injury is relatively short, then it can be recovered through nutritive drug treatment, together with rehabilitation training and hyperbaric oxygen therapy in the later stage. If the motor nerve injury is purely due to nerve entrapment syndrome or increased blood glucose, the symptoms can usually be relieved by lowering glucose and dehydration to reduce nerve root edema, along with neurotrophic treatment. If the motor nerve injury is very serious and the nerve is completely necrotic, it is generally not recoverable and often leaves some sequelae. For example, if the motor nerve is dissected due to traumatic injury, the injury cannot be recovered because the nerve cells cannot be regenerated. At this time, the family should pay attention to communicate with the patient to avoid a series of negative emotions, and at the same time, pay attention to take the patient to outdoor activities to divert the patient’s attention to the disease.
