AB  - Appropriate motor performance, which must be precisely processed and timed to 
      temporal and spatial requirements, can be studied using a synchronized tapping 
      task. For gait rehabilitation, estimation of bilateral foot-tapping accuracy is 
      important, as walking involves bilateral movements, usually antiphase, of the 
      lower extremities. Rhythmic control of lower limb movements, such as gait, 
      involves voluntary control and may also be automatically regulated by the central 
      pattern generator. This study investigated the temporal synchronization of 
      in-phase and antiphase movements using synchronized bilateral finger and 
      foot-tapping tasks. Thirty healthy young adult volunteers were enrolled and 
      instructed to tap the finger or foot button synchronously with the tones 
      presented at fixed inter-stimulus intervals (ISIs). One of 10 different ISIs 
      (250-4800 ms) was selected for each block, in which 110 tones were presented. 
      Taps were performed by either unilateral or bilateral fingers or feet, either 
      in-phase (to move bilateral fingers or ankles simultaneously) or antiphase (to 
      move bilateral fingers or ankles alternately). The synchronization error (SE) and 
      coefficient of variation (CV) of the inter-tap interval (ITI) were evaluated. In 
      all trials with short ISIs, SEs were narrowly distributed, either clustered 
      around 0 ms or with a slightly negative value. Although SE variability gradually 
      increased with increasing ISI, the CV of ITI was significantly lower for 
      antiphase movement than for unilateral or in-phase movement in the foot-tapping 
      task, but not in the finger-tapping task. The preserved temporal synchronization 
      for antiphase movement of the foot, but not finger tapping, may be due to the 
      neural mechanisms underlying locomotion.
