Subject: Peripheral Denervation in Cervical Dystonia (MovDis Congress 2000) Date: 6/20/2000 E-MOVE reports from the 6th International Congress of Parkinson's Disease and Movement Disorders, held in Barcelona, Spain, 11-15 June 2000. Citation numbers refer to abstract numbers published in Movement Disorders 2000;15 (Supplement 3).1. Selective peripheral denervation for cervical dystonia: Selection criteria R Benabou, P Molina-Negro, G Bouvier P 738 From experience with 450 cervical dystonia patients receiving selective peripheral denervation over 20 years, the authors propose the following selection criteria: --resistance to medical treatment, including BTX --stable clinical picture for at least 1, and preferably 3, years --dystonia restricted to or most pronounced in the cervical region They note that rotatory CD, either pure or combined with mild retro- or antecollis, shows the best post-operative outcome, while previous surgical operations, fibrosis, or arthritis reduce the likelihood of improvement. 2. Prospective study of selective peripheral denervation for botulinum-toxin resistant patients with cervical dystonia A Munchau, JD Palmer, D Dressler, J O'Sullivan, KL Tsang, M Jahanshahi, N Quinn, AJ Lees, KP Bhatia P712 Forty patients with BTX-resistant cervical dystonia received selective peripheral denervation. Mean follow-up of 9.4 months showed 60% of patients had significant functional improvement following surgery, with 25% reduction in TWSTRS score at 6 months and 1 year. At these two time points, severity subscore was reduced by 20% and 13% compared to baseline (p=0.01 for the difference ), disability subscore was reduced by 25% and 40% (p<0.0001), and pain subscore by 30% and 20% (n.s.). Six patients with primary BTX treatment failure obtained no benefit except 30% reduction of pain at 6 months. Mild-to-moderate dysphagia was reported in 12 patients, and persisted in 7. Severe dysphagia occurred in 2 patients, and persisted in 1. Swallowing improved in 4 patients. E-MOVE Editor: Richard Robinson, NASW, WE MOVE
