The patient with Wikipedia reference-linkbell's palsy should be treated right from the onset and physiotherapy treatment should not be delayed. In my opinion the sooner the patient gets the ultrasound therapy, the early is the recovery. If the patient gets his ultrasound treatment in the first week of onset he will be recovered varying from 1-3 weeks to 1 and half month. The more younger is the patient the better is the chances of recovery and vice versa.After three weeks from the onset if improvements does not seem to occur, the better is to also include the electrical stimulation with IDC. There is no room for the use of faradic current as it lead to the development of secondary contractures of facial muscles. PNF facial musculature exercises should be started as soon as there is any sign for activity of muscles. Generally IDC stimulation should be continued as long as there is not sufficient activity in muscles. You may also use the IDC to re educate the lost movements of facial muscles. However, as you know as a rule after two year of complete paralysis there is no room also for any kind of electrical stimulation as after two years there is complete atrophy and fibrosis of muscles. The only solution left afterwards is plastic surgery of the patient. Physiotherapy should be started after the operation to re- educate the movements of face. I hope this information will help you a little bit. With regards, sabah
