Nale ,

The problem is there is a like post before you to thank that post which endorse Ultrasound therapy and all electrotherapy in facial palsy .
Physiotherapists need to learn more ,reflect more ,search more ......in case of facial palsy we are facing great challange from those people with residuals following facial palsies .Any physio. may be lucky to encounter first Bell,s palsies which could resolve with nothing ,but in case of severe facial nerve affections ,residuals if the victim ,the therapist ,the society are aware of synkinesis every thing pass! They may say to the patient there was no chance better than what we did .

Cheers
