Dear Monica, You may be talking about muscle specific injections of Botulinum Toxin.There was an article entitled"Approch to the Treatment of Limb DisordersWith Botulinum Toxin A" Dr. Stanley Fahn of Col. Pres.Hosp.in NY city was one of the authors and he is well respected.The article appeared in the Arch Neurol1996:53:617-624 and while the focus is on the limbs it makes interesting reading. If you are unable to find a copy let me know and I will send you one. I have no idea whare you or yourdad reside but another name to keep in mind is Dr.Daniel Tarsey of the Deaconist Hosp. in Boston,Ma. The last phone # I had for him was 617-632-8837 and that number is up to date or so I've been told. I recall him writing about BTX injections in smaller muscles with positive results. Good luck to you and your dad George lussier [[log in to unmask]] [log in to unmask]
