Design outcomes

Primary

MeasureTime frame
It is expected to find attenuation of involuntary movements in patients with cervical dystonia after application of botulinum toxin using ultrasound or electromyography methods through scores on the Toronto Scale for the Assessment of Spasmodic Torticollis (TWSTRS). We will see results immediately before and four to six weeks after application.

Secondary
