Pre- and post-DBS examination. Presurgical baseline examination at 23 years of age and postsurgical gait 15 months after bilateral GPi DBS implantation. Laryngeal dystonia was present with speech. Dystonia was most prominent when walking and impaired her gait. Retrocollis, opisthotonus, right upper extremity flexion, and bilateral plantar flexion were present. DBS improved her dystonia and gait.

Axial (left) and coronal (right) T2-FLAIR brain MRI showed bilateral hypointensity of the globus pallidus with anterior medial hyperintensity, consistent with the “eye of the tiger” sign. L = left.
