Runner’s dystonia (RD) is a task-specific focal dystonia of the lower limbs that occurs when running. In this retrospective case series, we present surface electromyography (EMG) and joint kinematic data from thirteen patients with RD who underwent instrumented gait analysis (IGA) at the Functional and Biomechanics Laboratory at the National Institutes of Health. Four cases of RD are described in greater detail to demonstrate the potential utility of EMG with kinematic studies to identify dystonic muscle groups in RD. In these cases, the methodology for muscle selection for botulinum toxin therapy and the therapeutic response is discussed. Lateral heel whip, a proposed novel presentation of lower-limb dystonia, is also described.
跑者肌张力障碍（RD）是一种特定于任务的下肢局灶性肌张力障碍，发生在跑步时。在这项回顾性病例系列研究中，我们展示了来自 13 名 RD 患者的表面肌电图（EMG）和关节运动学数据，这些患者在国立卫生研究院的功能和生物力学实验室接受了仪器步态分析（IGA）。更详细地描述了四个 RD 病例，以展示肌电图与运动学研究相结合识别 RD 中拮抗肌群的潜在效用。在这些病例中，讨论了用于肉毒毒素治疗的肌肉选择和治疗反应的方法。还描述了一种新提出的下肢肌张力障碍的新表现形式——外侧足跟鞭打。
