Neuroplasticity After Spinal Cord Injury
Status unconfirmed · Not applicable
Conditions studied: Spinal Cord Injury
In brief
The long-term goal is to acquire scientific knowledge that can be used to develop mechanistic-driven intervention strategies aiming at restoring upper and lower-limb motor function in individuals with cervical or thoracic spinal cord injury (SCI). The proposed project will examine cortical, corticospinal, and spinal contribution to bilateral hand and arm muscle activity during bilateral movements and spinal contributions to lower limb muscle activity. By comparing changes in different sites within the Central Nervous System (CNS), the investigators may also identify key mechanisms that might be differentially affected by the injury, plasticity, and training.
