AB  - BACKGROUND: Better understanding of how bimanual coordination changes over the 
      first weeks of recovery after stroke is required to address the potential utility 
      for bimanual rehabilitation. Three-dimensional kinematic analysis can provide 
      quantitative assessment of unimanual and bimanual movements. OBJECTIVE: To assess 
      the natural evolution of reaching kinematics during standard poststroke 
      rehabilitation, focusing on bimanual coordination. METHODS: A total of 12 
      hemiparetic, moderately impaired patients were included within 30 days after a 
      first unilateral ischemic/hemorrhagic stroke; 7 kinematic assessments were 
      performed once a week for 6 weeks and at 3 months after inclusion. The 
      reach-to-grasp task was performed in 3 different conditions: unimanual with the 
      healthy limb (UN), unimanual with the paretic limb (UP), and bimanual (BN/BP). 
      RESULTS: For the paretic limb, movement fluency (number of movement units and 
      total movement time) was lower for bimanual reaching compared with unimanual 
      reaching. For bimanual reaching, (1) movement kinematics were similar for both 
      limbs, (2) recovery patterns of both limbs followed a similar profile with a 
      plateau phase at 6 weeks poststroke, and (3) intertrial variability of 
      between-hands synchronization decreased over sessions, although the mean delays 
      remained the same. CONCLUSIONS: Bimanual coordination started to become efficient 
      6 weeks after onset of stroke, so for patients such as those we tested, this time 
      could be most opportune to start bimanual-oriented rehabilitation. The challenge 
      in future research includes determining the characteristics of patients who may 
      best benefit from bimanual therapy.
