We developed an automated and objective method to measure posture and voluntary movements in patients with cervical dystonia using Fastrack, an electromagnetic system consisting of a stationary transmitter station and four sensors. The junction lines between the sensors attached to the head produced geometrical figures on which the corresponding aspects of the head were superimposed. The head position in the space was reconstructed and observed from axial, sagittal, and coronal planes. Four patients with cervical dystonia and 6 healthy subjects were studied. Each patient was representative of one of the typical patterns of cervical dystonia. The study allowed the authors to collect quantitative data on posture and range of motion of the head. This pilot study demonstrates the efficacy of the Fastrack system to objectively measure the head position in cervical dystonia patients.
我们开发了一种自动化的客观方法，使用Fastrack（一种由固定发射站和四个传感器组成的电磁系统）来测量颈部肌张力障碍患者的姿势和自主运动。连接到头部的传感器之间的连接线产生了几何图形，头部的相应部位叠加在这些图形上。头部在空间中的位置被重建，并从轴向、矢状面和冠状面进行观察。对4例颈部肌张力障碍患者和6名健康受试者进行了研究。每名患者代表一种典型的颈部肌张力障碍模式。该研究使作者能够收集有关头部姿势和活动范围的定量数据。这项初步研究证明了Fastrack系统在客观测量颈部肌张力障碍患者头部位置方面的有效性。
