Motor unit plasticity in stroke survivors: Altered distribution of gastrocnemius ’ action potentials
Introduction: Stroke leads to severe motor deficits, affecting balance control, lower limb function and gait. Motor impairments may persist even months after stroke [1,2] and are possibly associated with motor unit plasticity. Considering stroke leads to the death of motor neurons and the consequent reinnervation of orphan fibres by surviving motor neurons [1], it is possible that the territory of motor units increases after stroke. Here we investigate this issue with intramuscular and surface electromyograms (EMGs).
