What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine how neuromodulation, through electrical and magnetic stimulation, can improve movement in individuals with long-term spinal cord injuries. The researchers focus on identifying the optimal combination of these techniques to enhance mobility. Participants will use the RISES-T system, a non-invasive neuromodulation device, which provides stimulation during specific task practice. Ideal candidates have had a spinal cord injury for over a year and can participate in physical therapy. As an unphased trial, this study presents a unique opportunity to contribute to groundbreaking research that could enhance mobility for many.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the RISES-T System is safe for use in spinal cord injury patients?

Research has shown that the RISES-T System, which uses electrical signals on the spinal cord, has been tested for safety. Early studies found that this system is safe for people with spinal cord injuries. It works by sending small electrical signals to the spine to help improve movement.

In one study, researchers tested the safety of this technology and did not find any serious side effects. This suggests most people could use the system without major issues. Another study examined similar methods and found that they were generally well-tolerated, meaning people could use them without significant discomfort or harm.

Overall, the evidence so far suggests that the RISES-T System is safe for humans, with no major safety concerns reported in these studies. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Most treatments for spinal cord injury focus on rehabilitation exercises and medications that aim to manage symptoms and promote recovery. However, the RISES-T System is unique because it offers a non-invasive way to stimulate the spinal cord directly. This system uses closed-loop transcutaneous spinal cord stimulation, which means it can deliver electrical impulses through the skin to help improve motor functions while participants engage in repetitive task practice. Researchers are excited about this treatment because it could enhance the body's natural ability to heal and regain function without requiring surgery or long-term medication use.

What evidence suggests that the RISES-T System is effective for improving mobility in spinal cord injury?

Research has shown that the RISES-T System, which uses gentle electrical signals on the spine without surgery, may help people with spinal cord injuries. In one study, 72% of participants experienced significant improvements in arm movement. Another study found that combining electrical signals with physical exercises enhanced recovery in people with long-term spinal cord injuries, especially after several sessions. Some reports also mention improved bladder, bowel, and sexual function following spinal stimulation. While results can vary, these findings suggest potential benefits for movement and function in people with spinal cord injuries. Participants in this trial will receive closed-loop transcutaneous spinal cord stimulation via the RISES-T System while engaging in repetitive task practice. ^{1 2 3 5 6}

Are You a Good Fit for This Trial?

This trial is for individuals with chronic spinal cord injury or disease, at least a year post-injury, who can engage in therapy and have caregiver support. They must be able to consent and participate in recorded sessions. Those with severe medical conditions, uncontrolled symptoms, skin issues where electrodes attach, active implants like pacemakers, or are pregnant/breastfeeding cannot join.

Published Research Related to This Trial

A novel noninvasive stimulation strategy combined with pharmacological intervention successfully re-engaged spinal locomotor networks in individuals with motor complete paralysis, enabling locomotor-like stepping without voluntary effort during a single session.

After 18 weeks of treatment, all five subjects showed significant improvements in voluntary motor control, with evidence of re-established functional connectivity between the brain and spinal cord, allowing for selective muscle activation.

Electrochemical neuromodulation therapies and robot-assisted rehabilitation have shown promise in restoring voluntary leg movements in chronic paraplegic individuals, indicating potential for improving mobility after spinal cord injuries.

In rodent models, these therapies led to significant remodeling of neural pathways, suggesting that similar mechanisms may be effective in humans, although challenges remain in translating these findings into widespread clinical practice.

In a study involving 122 participants with chronic low back and/or leg pain, multiphase spinal cord stimulation (SCS) significantly reduced pain levels, with mean reductions of -4.3 and -4.7 on the numerical rating scale for two different multiphase therapies.

The multiphase SCS therapies were found to be safe, with only one non-serious device-related adverse event reported and no infections, suggesting a favorable safety profile for this new stimulation paradigm.

Spinal cord stimulation (SCS) is evolving from a treatment for intractable pain to a potential method for restoring function after spinal cord injuries, driven by advances in understanding spinal cord lesions and compensatory mechanisms.

New SCS strategies, like spatiotemporal neuromodulation, show promise but require intensive rehabilitation techniques to be effective, highlighting the need for well-designed clinical trials to evaluate safety and efficacy in real-world applications.

In a proof-of-concept study involving three adults with cervical spinal cord injury, repetitive QuadroPulse transcranial magnetic stimulation (rTMS(QP)) showed functional benefits, particularly in improving walking speed and cortical excitability without any adverse effects.

The combination of rTMS(QP) with targeted exercises led to even greater improvements in motor function, suggesting that this approach could be effective and warrants further investigation in larger studies.

Transcutaneous electrical stimulation of the spinal cord (TESS) significantly enhances motor-evoked potentials in arm muscles for up to 75 minutes after stimulation, indicating its potential to promote functional recovery in individuals with spinal cord injury (SCI).

The study found that TESS has a dual effect: it excites spinal networks while inhibiting cortical activity, which may contribute to improved hand and arm function, especially when using a specific 5 kHz carrier frequency during stimulation.
