The Book describes about the Bell's palsy is named for Sir Charles Bell, a 19th century Scottish surgeon who was the first to describe the condition. The disorder, which is not related to stroke, is the most common cause of facial paralysis. Generally, Bell's palsy affects only one of the paired facial nerves and one side of the face, however, in rare cases, it can affect both sides .In 1927, physical therapy treatment for Bell’s palsy was advocated. Gross facial exercises, massage, electrical stimulation and taping to lift a drooping, flaccid face were the treatment choice. These non-specific procedures continue to be recommended and practiced today.
