Is bimanual interference affected in the case of a central proprioceptive loss? New insight from a left-brain-damaged single-case study.

The movement of the unaffected hand induced a bimanual coupling effect on the movement of the affected one only when the visual input was available. In absence of a visual feedback, the aberrant proprioceptive information might preclude the emerging of bimanual coupling, even in the case of a preserved motor intentionality and planning.
