Multisite Transspinal Stimulation for Augmenting Recovery in Spinal Cord Injury
Sponsor: Maria Knikou, PT, MBA, PhD
Summary
A well-established rehabilitation strategy for improvements of standing and walking ability in persons with spinal cord injury (SCI) is step training on a motorized treadmill with body weight support. A promising intervention is stimulation of the spinal cord through the skin (transspinal). No single intervention is likely to significantly improve long-term function after SCI on its own. Rather, combinatorial treatments that work synergistically and can be used at different clinical settings is the answer to target recovery in people with SCI. The objective of this clinical trial is to develop a non-invasive combinatorial intervention that can be used worldwide in different clinical settings. The investigators will use cervical and lumbosacral transspinal stimulation to augment the benefits of locomotor training and affect vital body functions after SCI. The investigators will deliver non-invasive cervical and lumbosacral transspinal stimulation alone or with step training to improve upright posture, walking, bladder, sex, and bowel function in persons with incomplete SCI. The noninvasive nature of the intervention holds minimal risk that outweighs the benefits.

Interventions
Multisite transspinal stimulation at rest
The intervention, combined cervical and lumbar transspinal stimulation, will be used for the first time to reconnect the spared neuronal pathways of the injured human spinal cord. The intervention will be administered while at rest lying on the back or during robotic gait training. Cervical and lumbar transspinal stimulation will be delivered via surface active electrodes placed on the back of the neck and on low back, and four returning electrodes placed on each clavicle and iliac crest.
Multisite transspinal stimulation during robotic gait training
The intervention, combined cervical and lumbar transspinal stimulation, will be administered during robotic gait training. Cervical and lumbar transspinal stimulation will be delivered via surface active electrodes placed on the back of the neck and on low back, and four returning electrodes placed on each clavicle and iliac crest while participants step with the help of the Lokomat 6 Pro, a robotic device that helps the legs step. Locomotor training will depend on the ability of each participant to step without foot dragging. Over the training course, we will adjust the body weight support, ankle straps position, and leg guidance force. The tension of the ankle straps will be adjusted based on the right and left tibialis anterior muscle strength evaluated every 2 weeks. Body weight support and leg guidance force will be adjusted based on presence or absence of knee buckling during standing.
