Primary outcomePrimary: Dystonia Severity as Assessed by the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) — 13; 17 scores on a scale
Summary
Primary cervical dystonia (PCD) is the most common form of focal dystonia. PCD is frequently reported as a source of disability, decreased quality of life, and social stigma. Botulinum toxin (BoNT) is the gold standard treatment for PCD. The average duration of benefits from BoNT injections was about 9.5 weeks and BoNT treatment is known to provide only pure symptomatic benefits and does not seem to modify the disease pathophysiology.
The investigator plans to use repetitive transcranial magnetic stimulation (rTMS) therapy as an adjunctive therapy in combination with BoNT injections as a novel approach to treat PCD. The primary goal of this study is to compare standard treatment with BoNT versus BoNT combined with a two week course of rTMS.
