FIGURE 1.

Performance of patients playing Rhythm Workers and Tetris in the rhythmic oral diadochokinesis (A), paced manual (B), gait (C), and unpaced manual (D) tasks. (E,F) The post- minus pre-intervention difference score in the rhythm perception task, for each group. A positive difference score indicates an improvement of rhythm perception following the intervention. (F) The relation between an improvement in rhythm perception (perceptual difference score) and the change in rhythmic variability post- minus pre-intervention averaged across motor domains (post-motor variability difference score) for the Rhythm Workers group. A negative motor variability difference score indicates an improvement.
