Long-term outcomes of pallidal DBS for cervical dystonia

Background: Cervical dystonia (CD) can be disabling and often fails medical therapy in the long-term. Pallidal deep brain stimulation (DBS) is an effective option for selected patients. Here, we assess its efficacy over 10 years. Methods: All patients undergoing DBS for CD in Calgary were assessed u...

Description
Summary:Background: Cervical dystonia (CD) can be disabling and often fails medical therapy in the long-term. Pallidal deep brain stimulation (DBS) is an effective option for selected patients. Here, we assess its efficacy over 10 years. Methods: All patients undergoing DBS for CD in Calgary were assessed using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) at baseline, 6 months and 1 year post-op, and bi-annually thereafter. Primary outcome was severity (range 0-30, higher scores indicating greater impairment). Results: Seventeen patients underwent surgery with at least 2 year follow-up. Mean baseline TWSTRS severity score was 16.9+/-3.4 (+/-SD, n=17). Follow-up ranged from 2 to 10 yrs. Outcomes at each follow-up were significantly different from baseline (p
