StrokeTrack: Wireless Inertial Motion Tracking of Human Arms for Stroke Telerehabilitation


Stroke is a leading cause of disability in the United States and yet little technology is currently available for individuals with stroke to practice rehabilitation therapy progress in their homes. This paper presents StrokeTrack, an efficient, wearable upper limb motion tracking method for stroke rehabilitation therapy at home. StrokeTrack consists of two inertial measurement units (IMU) that are placed on the wrist and the elbow. Each IMU consists of a 3-axis accelerometer and a 3-axis gyroscope. In order to track the motion of the upper limb, StrokeTrack estimates the position of the forearm and upper arm by using inertial tracking algorithms and kinematical models. In the next step, StrokeTrack corrects the positions of the joints inferred from the inherent integra- tion drift, and updates them. Finally, dynamic time warping (DTW) is adopted in order to check the accuracy of the patient’s motions by matching them to the reference motions.
