Anomaly plots from a COMB exercise sequence by a post-stroke subject (from Kinect + IMU system). The first highlighted segment is a short pause at the midpoint between the table and the head which is an unusual pausing point. For the second and the third highlighted segments, the high reconstruction errors and the phase fluctuations are caused by an abnormal path of movement from the back of the head to the table. She moves her hand to the space in front of her belly first before moving to the table. However, in some repetitions (non-highlighted areas), she did it normally without receiving any external feedback
