Bimanual Motor Skill Learning in Acute Stroke

Recruiting now · Not applicable

Conditions studied: Stroke, Acute, Stroke, Subacute

In brief

The subacute phase of stroke provides a window into how a lesion perturbs sensorimotor functions prior to reorganisation driven by plasticity and neurorehabilitation. The recovery from motor impairment has been extensively studied, but it is currently unknown whether motor skill learning (MSkL) is enhanced or impaired during acute stroke, especially bimanual motor skill learning (bim-MSkL), which likely requires more motor-attentional-cognitive resources than unimanual MSkL. The goals of this project are: to determine the neural substrates critical to achieve proximal and distal bimanual motor skill learning (bim-MSkL) by specifying whether (sub)acute stroke to different brain areas (cortical and subcortical) induce specific deficits in bimanual and/or distal bim-MSkL, which behavioral components are involved in bim-MSkL, and whether damage to the motor, sensory and inter-hemispheric pathways specifically impairs proximal and/or distal bim-MSkL.
