Abstract

Here an inertial sensor-based monitoring system for measuring and analyzing upper limb movements is presented. The final goal is the integration of this motion-tracking device within a portable rehabilitation system for brain injury patients. A set of four inertial sensors mounted on a special garment worn by the patient provides the quaternions representing the patient upper limb's orientation in space. A kinematic model is built to estimate 3D upper limb motion for accurate therapeutic evaluation. The human upper limb is represented as a kinematic chain of rigid bodies with three joints and six degrees of freedom. Validation of the system has been performed by co-registration of movements with a commercial optoelectronic tracking system. Successful results are shown that exhibit a high correlation among signals provided by both devices and obtained at the Institut Guttmann Neurorehabilitation Hospital.

摘要

这里提出了一种基于惯性传感器的监测系统，用于测量和分析上肢运动。最终目标是将这种运动跟踪设备集成到用于脑损伤患者的便携式康复系统中。一套安装在患者特殊服装上的四个惯性传感器提供表示患者上肢在空间中方向的四元数。建立了一个运动学模型来估计 3D 上肢运动，以进行准确的治疗评估。人体上肢被表示为具有三个关节和六个自由度的刚性体运动链。通过与商业光电跟踪系统的运动配准对系统进行了验证。在 Institut Guttmann 神经康复医院获得的结果表明，两种设备提供的信号之间具有高度相关性。
