步态分析通常用于识别临床人群和老年人的步态变化和跌倒风险。基于身体佩戴的惯性传感器的步态分析提供了一个可行的替代验光和压力为基础的测量时空步态特征。我们评估了与标准固定跑步机（Zebris（R））相比，身体佩戴的惯性传感器系统（RehaGait（R））测量时空步态特征的有效性以及相对和绝对可靠性。时空步态参数（步行速度，步长，节奏和步幅时间）收集了24名健康老年人（年龄：75.3 +/- 6.7岁）测试2天（间隔1周），同时使用传感器为基础的系统和仪器跑步机。每个参与者以不同的步行速度和坡度完成步行测试（200步）。RehaGait（R）系统和跑步机之间的差异是微不足道的（科恩的d
Gait analysis is commonly used to identify gait changes and fall risk in clinical populations and seniors. Body-worn inertial sensor based gait analyses provide a feasible alternative to optometric and pressure based measurements of spatiotemporal gait characteristics. We assessed validity and relative and absolute reliability of a body-worn inertial sensor system (RehaGait (R)) for measuring spatiotemporal gait characteristics compared to a standard stationary treadmill (Zebris (R)). Spatiotemporal gait parameters (walking speed, stride length, cadence and stride time) were collected for 24 healthy seniors (age: 75.3 +/- 6.7 years) tested on 2 days (1 week apart) simultaneously using the sensor based system and instrumented treadmill. Each participant completed walking tests (200 strides) at different walking speeds and slopes. The difference between the RehaGait (R) system and the treadmill was trivial (Cohen's d
