Anomaly plots from a TAP exercise sequence by a post-stroke subject (from Kinect + IMU system). Her arm constantly shakes whenever the hand is lifted against gravity and has no anchor point to push against. This shaking pulls the wrist position out from the proper trajectory sometimes. In addition, her forearm pronation keeps rolling back and forth throughout the exercise resulting in high reconstruction errors (FA Prn., dark cyan)
