How long should infrared therapy be applied for facial paralysis?
Facial paralysis generally refers to facial nerve palsy. Infrared therapy for facial nerve palsy usually involves irradiation for 10 to 20 minutes per session. Specific details are as follows:
Facial nerve palsy is a condition characterized by facial muscle paralysis due to damage of the facial nerve. It may result from facial infection with the herpes virus, or from metabolic disturbances caused by diabetes. Common symptoms include expressionless face, drooping of the mouth corner, and drooling. During the recovery phase of facial nerve palsy, infrared irradiation can typically be used as a treatment method, administered twice daily, with each session lasting between 10 and 20 minutes. The specific heat emitted by infrared radiation can, to some extent, accelerate local blood circulation and metabolism, helping to improve muscle function. However, infrared irradiation should only be considered an adjunctive therapy; using infrared irradiation alone generally does not achieve sufficient therapeutic effect.
It is recommended that individuals experiencing facial nerve palsy seek prompt medical treatment at a hospital. Delaying treatment may lead to disease progression and potentially permanent impairment of facial nerve function.
