Functional magnetic resonance imaging (fMRI) of the sensorimotor cortex in spinal cord injury patient after intensive rehabilitation

Functional magnetic resonance imaging (fMRI) of the sensorimotor cortex in spinal cord injury... PurposeThe sensorimotor cortex may play a role in the functional recovery after a spinal cord injury (SCI) through efference generated in the absence of the afference. The purpose of this study was to evaluate the potential reorganization in the sensorimotor cortex in SCI patients after body weight supported treadmill training (BWSTT) associated with conventional motor rehabilitation.MethodsSeven SCI patients with American Spinal Injury Association Impairment Scale (AIS) C and D participated in this study. SCI patients were submitted to a motor task functional magnetic resonance imaging study (fMRI) before and after the rehabilitation treatment.ResultsAll patients showed significant changes in the brain activation following motor rehabilitation. After treatment, a decrease in the activation of the cerebellum and an increase of basal ganglia activation were observed.ConclusionThe results suggest that the cerebellum is less recruited when acquiring an automatic movement, and the basal ganglia contribute to the cortical reorganization process to promote a functional motor recovery. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Biomedical Engineering Springer Journals

Abstract

PurposeThe sensorimotor cortex may play a role in the functional recovery after a spinal cord injury (SCI) through efference generated in the absence of the afference. The purpose of this study was to evaluate the potential reorganization in the sensorimotor cortex in SCI patients after body weight supported treadmill training (BWSTT) associated with conventional motor rehabilitation.MethodsSeven SCI patients with American Spinal Injury Association Impairment Scale (AIS) C and D participated in this study. SCI patients were submitted to a motor task functional magnetic resonance imaging study (fMRI) before and after the rehabilitation treatment.ResultsAll patients showed significant changes in the brain activation following motor rehabilitation. After treatment, a decrease in the activation of the cerebellum and an increase of basal ganglia activation were observed.ConclusionThe results suggest that the cerebellum is less recruited when acquiring an automatic movement, and the basal ganglia contribute to the cortical reorganization process to promote a functional motor recovery.
