Facial paralysis exercise, also called facial paralysis recovery exercise, belongs to one of the rehabilitation treatments for idiopathic facial nerve paralysis, which can be started after the patient is diagnosed with idiopathic facial nerve paralysis. The main clinical symptom of idiopathic facial nerve paralysis is the paralysis of facial expression muscles on the affected side, and the patient will have a series of symptoms such as the disappearance of frontal lines, shallow nasolabial folds, incomplete eyelid closure, and crooked corners of the mouth. Facial paralysis recovery exercise is a rehabilitation training method for facial expression muscle paralysis. Facial paralysis recovery exercise can be divided into five steps, which are eyebrow raising training, eyes closed training, mouth training, showing teeth training and cheek training. The earlier the rehabilitation training, the better the effect on the recovery of facial paralysis symptoms, so it is recommended that patients start doing it after diagnosis. Doing facial palsy exercises is only an adjunctive treatment for patients with idiopathic facial nerve palsy. After the occurrence of facial paralysis, it is recommended to go to the neurology department of the hospital immediately, and develop a more comprehensive treatment plan with the help of doctors.
