Digital mobility assessment using wearable sensor systems has the potential to capture walking performance in a patient's natural environment. It enables the monitoring of health status and disease progression and outcome evaluation of interventions in real-world situations. In contrast to laboratory settings, real-world walking occurs in non-conventional environments and under unconstrained and uncontrolled conditions. Despite the general understanding, there is a lack of agreed definitions about what constitutes real-world walking, impeding the comparison and interpretation of the acquired data across systems and studies. Hence, there is a need for a terminological framework for the guidance of further algorithmic implementation of digital measures for gait assessment. We used an objective methodology based on an adapted Delphi process to obtain consensus on specific terminology related to real-world walking by asking a diverse panel of clinical, scientific, and industrial stakeholders. Six constituents ("real-world", "walking", "purposeful", "walking bout", "walking speed", "turning") have successfully been defined in two feedback rounds. The identification of a consented set of real-world walking definitions has important implications for the development of assessment and analysis protocols, as well as for the reporting and comparison of digital mobility outcomes across studies and systems. The definitions will serve as a common framework for implementing digital and mobile technologies for gait assessment.

基于共识的数字移动性监控框架

使用可穿戴传感器系统的数字移动性评估具有捕获患者自然环境中步行性能的潜力。它可以监视健康状况和疾病进展，并在实际情况下评估干预措施的结果。与实验室设置相反，真实世界中的行走发生在非常规环境中以及不受约束和不受控制的条件下。尽管有普遍的了解，但对于组成真实世界的步行尚缺乏一致的定义，这妨碍了跨系统和研究对获取的数据进行比较和解释。因此，需要一种术语框架来指导用于步态评估的数字测量的进一步算法实现。我们通过询问各种临床，科学和工业利益相关者小组，使用了基于适应性Delphi流程的客观方法，以就与现实世界行走相关的特定术语达成共识。在两个反馈回合中已成功定义了六个要素（“现实世界”，“步行”，“有目的”，“步行回合”，“步行速度”，“转弯”）。一组公认的现实世界步行定义的确定对于评估和分析协议的开发以及跨研究和系统的数字移动结果的报告和比较具有重要意义。这些定义将作为实施步态评估的数字和移动技术的通用框架。
