Unraveling gait and balance impairment in cervical dystonia: associated features, functional implications, and the effect of botulinum toxin

This study confirms subtle gait and balance abnormalities in CD, with SLV emerging as a potential biomarker of functional impairment. HT appears to exacerbate balance dysfunction, while BoNT may partly improve sway in this subgroup. These findings suggest that sensor-based gait analysis may complement clinical evaluation and guide management in CD.
