当量化步态力学时，重要的是确保受试者在步态分析试验期间保持一致的步行速度。大多数测量步行速度的方法直到受试者完成试验后才产生数据。这通常会导致从分析中丢弃已完成的试验，因为受试者的速度不在可接受的范围内。位置数据的实时反馈可用于在必要时帮助受试者在试验期间调整其行走速度。14名参与步态分析的受试者使用实时反馈来监测他们的步行速度，结果显示，他们能够分别在90%和80%的试验中保持在目标步行速度的可接受范围内（每个受试者的首选速度和首选速度的150%）。这种方法可以在不使用额外设备的情况下准确有效地收集数据。
When quantifying the mechanics of gait, it is important to ensure that subjects maintain a consistent walking velocity during gait analysis trials. Most methods of measuring walking velocity do not produce data until after the subject has completed the trial. This often results in discarding completed trials from analysis because the subject's velocity was not within an acceptable range. Real-time feedback of position data can be used to help subjects adjust their walking velocity during the trial, when necessary. Results from 14 subjects who participated in gait analysis using real-time feedback to monitor their walking velocity show that they were able to stay within an acceptable range of their target walking velocities (each subject's preferred velocity and 150% of their preferred velocity) during 90% and 80% of trials, respectively. This method allows for accurate and efficient data collections without the use of additional equipment.
