Interlimb neural coupling: Implications for poststroke hemiparesis

K.N. Arya, S. Pandian
2014 Annals of Physical and Rehabilitation Medicine  
The coordination occurs due to spatiotemporal coupling of movements, which also comprises interactions in segmental kinematics, joint dynamics, and muscle activity.  ...  In stroke, bimanual motor impairments exist in the form of asymmetry and reduced coordination, which may be related to weakness of the ipsilateral body side lesser than the contralateral side.  ...  Further, asymmetry in bimanual force production is also evident.  ...
