Thank you for pointing out this surgical treatment option for cervical dystonia. Selective denervation has been performed on more than 2,000 patients since being developed in the 1980s. Patients considering the procedure must be evaluated by a neurosurgeon, have an electromyography test to determine the affected muscles, and be videotaped to study their movement. Afterwards, it is important that patients do exercises to improve their posture and improve the range of movement. For more information, go to http://bit.ly/1e6Mp2s.
