Reverse habit therapy does it work for severe vocal tic tourette?

Yes. While additional controlled trials are needed, habit reversal (hr), is safe, effective and a viable option. Hr sessions include instruction on awareness, competing response, and social support training. The competing response involved diaphragmatic breathing for 1 min contingent on the vocal tics or their antecedents. Please see http://www.Ncbi.Nlm.Nih.Gov/pmc/articles/pmc1284423/pdf/12723873.Pdf.
