Background Cervical dystonia is a movement disorder characterized by involuntary and sustained contraction of the neck muscles that determines abnormal posture. The aim of this study was to investigate whether dystonic posture in patients with cervical dystonia affects walking and causes postural changes. Methods Patients with cervical dystonia and a group of age-matched healthy controls underwent an instrumental evaluation of the Timed Up and Go Test. Findings All the spatio-temporal parameters of the sub-phases of the Timed up and go test had a significantly higher duration in cervical dystonia patients compared to the control group while no differences in flection and extension angular amplitudes were observed. Indeed, we found that Cervical Dystonia patients had abnormalities in turning, as well as in standing-up and sitting-down from a chair during the Timed up and go test than healthy controls. Interpretation Impairment in postural control in cervical dystonia patients during walking and postural changes prompts to develop rehabilitation strategies to improve postural stability and reduce the risk of fall in these patients.
颈肌张力障碍是一种运动障碍，其特征是颈部肌肉不自主且持续收缩，导致异常姿势。本研究旨在探讨颈肌张力障碍患者的异常姿势是否会影响行走并引起姿势变化。
颈肌张力障碍患者和一组年龄匹配的健康对照组接受了计时起立行走测试的仪器评估。
与对照组相比，颈肌张力障碍患者的计时起立行走测试的所有时相参数的持续时间明显更长，而屈伸角度幅度没有差异。事实上，我们发现颈肌张力障碍患者在计时起立行走测试中转身、从椅子上站起来和坐下时存在异常。
颈肌张力障碍患者在行走和姿势变化过程中出现姿势控制障碍，提示应制定康复策略来改善姿势稳定性，降低这些患者跌倒的风险。
