Development of a Novel Strategy to Analyze the Effect on Gait Using Transcutaneous Spinal Current Stimulation in Incomplete Spinal Cord Injured Patients

Details

Methodology: This task will involve the clinical and functional assessment of patients completing gait training with and without tSCS as defined in T4.2 to demonstrate the effects of tSCS and define the most favorable parameters. During this task, the assessments that will be completed will be defined by IG and then carried out according to the methodology that is set and agreed upon. Assessments will need to evaluate several factors: * The American Spinal Cord Injury Association Impairment Scale (ASIA) and the International Standards for Neurological Classification of Spinal Cord Injury (ISNSCI)38 will be used to determine level and severity of SCI and to evaluate sensory and motor deficit. * For gait outcome measures, 10 meters walking test (10MWT) and Walking Index for SCI (WISCI) II will be assessed. * For spasticity evaluation, Modified Ashworth modified score (MAS) will be used. * Neurophysiological studies may be included to study: 1) spinal cord excitability using F and H wave, 2) corticospinal conduction using transcraneal magnetic stimulation for MEP recording, and 3) muscle activity using surface EMG recording of lower limb muscles.
