Changes in cursor paths for a representative participant of the Dis2s-Rhy (A) and Rhy-Dis2s (B) groups. The blue and red trajectories represent the cursor paths for the discrete and rhythmic movements, respectively. After the baseline session (20 discrete movements and 40 s rhythmic movement), the participants performed 50 discrete movements and 100 s rhythmic movement under the presence of 30° counterclockwise visual rotation (rotation session). In each session, the Dis2s-Rhy group performed the discrete movement trial first, while the Rhy-Dis2s group performed the rhythmic movement trial first. Both participants were able to move the handle toward the target properly by the end of the first part of the rotation session. This appropriate movement direction was maintained in the following rhythmic cycles for the Dis2s-Rhy participant (A), but the cursor path of the first discrete trial after the rhythmic movement training was largely deviated from the target direction for the Rhy-Dis2s participant (B).
