Changes in behavior and posture observed over 30 min for patient P5. The main behavior engaged in at each time point is represented by a black line in the top graph. The black square represents movement or posture changes scored upon first review of the video. The black triangle indicates a movement that was added after a second review of the video when striking fluctuations in the near-infrared spectroscopy (NIRS) measurements were observed for this patient with no corresponding change in behavior or motion.
