Frequency of occurrences of the latent states (numbered 0–4) present in sessions corresponding to different tasks and BARS subscores (BARS right arm subscore for finger-nose-finger and alternating hand movements, BARS right leg subscore for heel-shin). The dynamics associated with a state are common across all tasks. Note the variation in frequency of state based on task and severity of ataxia score. For instance, within the alternating hand movements task there seems to be a systematic trade off between the frequency of occurrence of states 0 and 4 as the BARS arm score increases.
