About this study
People with spinal cord injury (SCI) have motor dysfunction that results in substantial social, personal, and economic costs. Uncontrolled muscle spasticity and motor dysfunction result in disabilities that significantly reduce quality of life. Several rehabilitation interventions are utilized to treat muscle spasticity and motor dysfunction after SCI in humans. However, because most interventions rely on sensory afferent feedback that is interpreted by malfunctioned neuronal networks, rehabilitation efforts are greatly compromised. On the other hand, changes in the function of nerve cells connecting the brain and spinal cord have been reported following repetitive electromagnetic stimulation delivered over the head and legs or arms at specific time intervals. In addition, evidence suggests that electrical signals delivered to the spinal cord can regenerate spinal motor neurons in injured animals. A fundamental knowledge gap still exists on neuroplasticity and recovery of leg motor function in people with SCI after repetitive transspinal cord and transcortical stimulation. In this project, it is proposed that repetitive pairing of transspinal cord stimulation with transcortical stimulation strengthens the connections between the brain and spinal cord, decreases ankle spasticity, and improves leg movement. People with motor incomplete SCI will receive transspinal - transcortical paired associative stimulation at rest and during assisted stepping. The effects of this novel neuromodulation paradigm will be established via clinical tests and noninvasive neurophysiological methods that assess the pathways connecting the brain with the spinal cord.
Read the detailed description
Motor dysfunction after SCI results in substantial personal, social, and economic costs. Secondary complications related to muscle spasticity and motor dysfunction significantly reduce quality of life. Rehabilitation efforts are compromised because most therapeutic interventions rely heavily on sensory afferent feedback that is interpreted by malfunctioned neuronal networks. On the other hand, electrical signals delivered over the spine regenerate neurons of the spinal cord in injured animals, and paired associative stimulation produces enduring neuronal plasticity in healthy and injured humans and animals. A fundamental knowledge gap still exists on induction of functional neuroplasticity and recovery of leg motor function following repetitive pairing of transspinal cord stimulation with transcortical stimulation in people with motor incomplete SCI. Our central working hypothesis is that transspinal cord stimulation paired with transcortical stimulation strengthens corticospinal neuronal connections, decreases ankle spasticity, and improves leg motor function. This notion is based on the concept tested in the applicant's laboratory that this novel stimulation paradigm potentiates synaptic actions and activity of spared but compromised axons providing the necessary environment for functional neuroplasticity. The rationale of this research study is that neuromodulation methods that can modify effectively the input-output relations of cortical and spinal neuronal pathways in people with motor incomplete SCI are needed. Based on strong preliminary data, two specific aims will be addressed: Specific Aim 1: Establish induction of transspinal-transcortical paired associative stimulation (PAS) neuroplasticity and improvements in leg sensorimotor function in people with motor incomplete SCI when PAS is administered during robotic-assisted gait training. Cortical and corticospinal neuronal circuits via state-of-the-art neurophysiological methods in seated (Aim 1A), soleus H-reflex excitability during assisted stepping (Aim 1B), and sensorimotor function evaluated via standardized clinical tests (Aim 1C) will be assessed before and after 15 sessions of transspinal-transcortical PAS delivered with subjects supine. Specific Aim 2: Establish induction of transcortical-transspinal PAS neuroplasticity and improvements in leg sensorimotor function in people with motor incomplete SCI when PAS is administered during assisted stepping. Cortical and corticospinal neuroplasticity via state-of-the-art neurophysiological methods in seated (Aim 2A), soleus H-reflex excitability during assisted stepping (Aim 2B), and leg sensorimotor function evaluated via standardized clinical tests (Aim 2C) will be assessed before and after 15 sessions of transspinal-transcortical PAS delivered during assisted stepping. It is hypothesized that transspinal-transcortical PAS delivered at rest or during assisted stepping strengthens corticospinal connections, increases spinal inhibition, decreases ankle spasticity, and improves leg motor function. Further, transspinal-transcortical PAS delivered during assisted stepping normalizes the abnormal phase-dependent soleus H-reflex modulation commonly observed during stepping in people with motor incomplete SCI. To test the project hypotheses, 12 people with motor incomplete SCI will receive 20 sessions of transspinal-transcortical or transcortical-transspinal PAS during assisted stepping. In people with SCI, and assess improvements in leg motor function with standardized clinical tests. In all subjects, assessments of neuroplasticity in cortical, corticospinal, and spinal neuronal networks will be administered. These results will advance considerably the field of spinal cord research and change the standard of care because there is great potential for development of novel and effective rehabilitation strategies to manage spasticity and improve motor function after SCI in humans.

Neurophysiological tests probing cortical and corticospinal excitability will be measured before and after the intervention. Single-pulse transcranial magnetic stimulation (TMS) will be used to assemble the recruitment curve of motor evoked potentials, and paired-pulse TMS will be used to probe changes in cortical inhibitory and facilitatory neuronal circuits.

Plasticity of spinal neural cicuits
Neurophysiological tests probing spinal reflex excitability will be measured before and after each intervention by posterior tibial and sural nerves stimulation during Lokomat-assisted stepping depicting the amplitude modulation of the soleus H-reflex, tibialis anterior flexor reflex, and interlimb reflexes.

Several rehabilitation interventions are utilized to treat muscle spasticity and motor dysfunction after SCI in humans.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Plasticity of cortical and corticospinal neural circuits (time frame: 3 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04624607, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Nov 2020.
