Fig 3. Motor behaviour parameters in healthy subjects (HS) and patients with Gilles de la Tourette syndrome (TS) during the execution of single- hand finger sequence with the right hand (RH-S) and during bimanual finger sequence with the right (RH-B) hand.

A–B: ordinate, value of TD and ITI in milliseconds; C: ordinate, % of CORRECT MOVEMENTS in percentage on total movements. Means ± standard errors of mean (SEM) of data are shown. Asterisks indicate when statistical analysis showed a significant difference (* p < 0.05, ** p < 0.01).
