20 patients with idiopathic cervical dystonia were randomized to undergo a 12 week program of active neck exercises and relaxation or relaxation alone, to determine the efficacy of physiotherapy in treating condition. Following evaluations over 16 weeks, the results indicated that there were no significant differences in any of the outcome measures between the two groups. However, it should be noted that the improvement in the Toronto Western Spasmodic Torticollis Rating Scale and quality of life scores was greater in the exercise group. There were also no adverse events reported by any patients.
