The purpose of this study is to investigate gait in patients with neurological disorders using accelerometers. Accelerometers were placed on both ankles of participants undergoing gait analysis. Data were collected during the 10-min walk test from healthy participants (n = 20) and patients with neurological deficits (n = 22) scheduled for surgery. Additional data were obtained after surgery for comparison. Both the time and frequency domain features were compared between healthy participants and patients. The interval between successive heel-strikes differed significantly, as did that between successive toe-offs. These features were correlated in healthy participants but not in patients, for whom the correlation coefficients tended to increase after surgery, indicating that the correlations can be used to monitor gait recovery and ankle-worn accelerometers were effective in collecting data for gait monitoring.

本研究的目的是使用加速度计研究神经系统疾病患者的步态。将加速度计放在进行步态分析的参与者的两个脚踝上。在10分钟步行测试期间收集了健康参与者（n  = 20）和神经系统缺陷患者（n = 22）计划进行手术。手术后获得其他数据进行比较。在健康参与者和患者之间比较了时域和频域特征。连续的脚跟敲击之间的间隔与连续的脚趾敲击之间的间隔有很大差异。这些特征在健康参与者中相关，而在患者中则不相关，因为相关系数倾向于在手术后增加，这表明该相关可用于监测步态恢复，而脚踝磨损加速度计可有效收集用于步态监测的数据。
