Abnormal lateralization of fine motor actions in Tourette syndrome persists into adulthood
Fig 1
Subject performed with eyes closed a finger opposition movement task (opposition of thumb to index, medium, ring and little fingers), following an acoustic cue set at 2 Hz. The task was executed with right hand only (single hand task; RH-S) or both the right (RH-B) and left (LH-B) hands simultaneously (bimanual task). The analysis was planned to study for movement lateralization and bimanual coordination.
