A 27-year-old woman presented with generalized dystonia that began at age 15 years as dystonic posturing of the right hand when writing. She was diagnosed with cervical dystonia and botulinum toxin injections were tried, providing minimal pain relief and no improvement of the dystonia. The cervical dystonia was partially responsive to sensory tricks (Video, A). She was most bothered by her cervical dystonia, and disability was 6 on Part II of the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS).
