Recovery of the walking function is one of the most common rehabilitation goals of neurological patients. Sufficient and adequate sleep is a prerequisite for recovery or training. To objectively monitor patients' progress, a combination of different sensors measuring continuously over time is needed. A sensor-based technological platform offers possibilities to monitor gait and sleep. Implementation in clinical practice is of utmost relevance and has scarcely been studied. Therefore, this study examined the feasibility of a sensor-based technological platform within the clinical setting. Participants (12 incomplete spinal cord injury (iSCI), 13 stroke) were asked to wear inertial measurement units (IMUs) around the ankles during daytime and the bed sensor was placed under their mattress for one week. Feasibility was established based on missing data, error cause, and user experience. Percentage of missing measurement days and nights was 14% and 4%, respectively. Main cause of lost measurement days was related to missing IMU sensor data. Participants were not impeded, did not experience any discomfort, and found the sensors easy to use. The sensor-based technological platform is feasible to use within the clinical rehabilitation setting for continuously monitoring gait and sleep of iSCI and stroke patients.
恢复行走功能是神经科患者最常见的康复目标之一。充足和适当的睡眠是康复或训练的前提。为了客观监测患者的进展，需要结合不同的传感器来进行长时间的连续测量。基于传感器的技术平台为监测步态和睡眠提供了可能。但它在临床实践中的实施至关重要，却鲜有研究。因此，本研究在临床环境中检验了基于传感器的技术平台的可行性。参与者（12 名不完全性脊髓损伤 (iSCI) 患者和 13 名脑卒中患者）被要求在白天将惯性测量单元 (IMU) 戴在脚踝周围，同时在一周内将床传感器放在床垫下。基于缺失数据、误差原因和用户体验来确定可行性。缺失测量日和夜的百分比分别为 14%和 4%。导致测量日数据丢失的主要原因与 IMU 传感器数据丢失有关。参与者没有感到不适，没有受到任何阻碍，并且认为传感器易于使用。基于传感器的技术平台可在临床康复环境中用于连续监测 iSCI 和脑卒中患者的步态和睡眠。
