• Conditions: Spinal Cord Injuries; Spinal Cord Injury at C5-C7 Level; Paraplegia, Spinal; Paraplegia, Incomplete

• Registration Number: NCT06272279
• Lead Sponsor: University of Manitoba

Brief Summary

This is a pilot research study to test the protocols needed for transcutaneous spinal electrical stimulation in persons living with spinal cord injury (SCI). Up to 24 participants will be enrolled. A variety of stimulation parameters and outcome measures will be assessed.

Detailed Description

Purpose of this project

Spinal cord stimulation has the potential to improve motor function recovery after spinal cord injury. Commonly used approaches include low-intensity, direct current (DC) stimulation applied across multiple segments, electrical transcutaneous (ETC) stimulation, and magnetic transcutaneous stimulation (MTC).

Objective: to evaluate and compare the voluntary and reflexive motor performance in the same subjects, including people with and without spinal cord injury, after non-invasive spinal cord stimulation interventions. Comparing two different interventions applied in different experimental sessions and the respective sham stimulation is the goal of this study.

corticospinal and spinal motor pathways in paraplegics and in non-injured humans will be tested.

Primary Outcome Measures

Name	Time	Method
Motor evoked potentials	Immediately after stimulation (within 1-15 min)	MEP input-output curve
Motor response	Immediately after stimulation (within 1-15 min)	H-reflex input output curve
