Abstract
Better understand how bimanual coordination
evolves during the first weeks of natural recovery after
stroke is needed to address bimanual rehabilitation. 15
stroke patients realized seven kinematic assessments
once a week during six weeks and at three months. The
grasping task was performed through 3D-movement
analysis in three different conditions: unimanual with
the non-paretic limb, unimanual with the paretic limb,
and bimanual.
Inter-limb coordination became efficient about 6
weeks after stroke, represented by a plateau phase.
Bimanual coordination is optimized around this period
of recovery, indicating a possible beneficial effect of
bimanual rehabilitation. Moreover, inter-limb
coordination recorded at movement onset and at
movement goal did not evolve over recovery.
1. Introduction
After rehabilitation, about 80% of post-stroke
patients still suffer upper limb disability, which impairs
their daily living activities and often leads to major
incapacities. One of the promising techniques in stroke
rehabilitation is the bimanual training, using inter-limb
coordination to favor motor recovery. In a bimanual
task, both upper limbs influence and are dependent on
each other to perform the task. This process entails that
the non-paretic limb involves the paretic limb and
improves its output [1] but also that the paretic limb
compels the non-paretic limb to match the affected
limb lower capabilities.
Bimanual training has been proven efficient [2].

The goal of the present study is to observe and
characterize the evolution of movement kinematics in
stroke patients during the first three months of standard
rehabilitation (no specific bimanual rehabilitation
added), and with a focus on bimanual coordination. We
also address which relevant factors may predict the
efficiency of bimanual rehabilitation.
