What You Need to Know Before You Apply

What is the purpose of this trial?

The trial explores a new device called the Portable Neuromodulation Stimulator (PoNS), which is placed on the tongue. The goal is to determine if this device, combined with balance training, can improve balance and walking in stroke survivors. Participants may receive either the actual device or a sham (inactive device for comparison). This trial suits individuals who had a stroke at least six months ago and continue to experience difficulties with leg movement and walking. As an unphased trial, it offers a unique opportunity to contribute to groundbreaking research that could enhance rehabilitation options for stroke survivors.

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 Portable Neuromodulation Stimulator is safe for improving balance post-stroke?

Research has shown that the Portable Neuromodulation Stimulator (PoNS) is generally safe and well-tolerated. Studies have confirmed its safety, although testing continues for stroke rehabilitation. While not yet approved in the United States specifically for stroke, it has a strong safety record in other applications. No reports have linked PoNS to serious side effects. However, as studies continue, researchers are collecting more data to confirm its safety for stroke recovery. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the Portable Neuromodulation Stimulator because it offers a novel approach to stroke recovery by combining electrical stimulation with balance training. Unlike standard treatments, which often rely on physical therapy alone, this device targets the nervous system directly to potentially enhance neuroplasticity, the brain's ability to reorganize and form new connections. This dual-action approach not only aims to improve balance and motor function more effectively but also could accelerate recovery times compared to traditional methods. By offering a portable solution, it provides a more accessible option for patients, enabling consistent use outside clinical settings.

What evidence suggests that the Portable Neuromodulation Stimulator is effective for improving balance post-stroke?

Research has shown that the Portable Neuromodulation Stimulator (PoNS), which participants in this trial may receive, can improve balance and walking in people who have had a stroke. In earlier studies, participants experienced noticeable improvements in balance and gait, suggesting that this device might aid recovery. The PoNS device sends signals to the brain through the tongue, potentially enhancing movement and stability. Other studies have also reported positive results for balance and movement, supporting the idea that PoNS therapy could benefit stroke recovery. Although this treatment is still under investigation, early results are promising. ^{1 2 6 7 8}

Published Research Related to This Trial

Vestibular rehabilitation may improve gait performance in post-stroke patients, as indicated by two out of three studies reviewed, which assessed outcomes using tests like the 10-Meter Walking Test and Timed Up and Go Test.

However, the overall evidence is considered very low quality due to issues like small sample sizes and lack of blinding, suggesting that more rigorous and larger studies are necessary to confirm these findings.

In a study of 49 stroke patients, balance training combined with electromyogram-triggered functional electrical stimulation (EMG-triggered FES) significantly improved both static and dynamic balance compared to conventional training alone.

The experimental group also showed notable enhancements in ankle muscle activation on the affected side, indicating that EMG-triggered FES is an effective intervention for improving balance and muscle function in stroke rehabilitation.

A local vibration stimulus training program significantly improved postural sway and gait in 31 chronic stroke patients compared to a sham group, with notable enhancements in both standing balance and walking metrics after six weeks of training.

The training group showed greater improvements in postural sway distance and velocity, as well as gait speed, cadence, step length, and single limb support time, indicating that this intervention can effectively aid rehabilitation in stroke patients.

Peripheral somatosensory stimulation (PSS) shows immediate benefits for postural stability after a single session in stroke rehabilitation, based on a systematic review of 20 studies.

Long-term improvements in postural recovery were observed when PSS was used as an additional therapy alongside exercises, although the specific impact on the paretic leg's contribution to posture remains uncertain.

Vagus nerve stimulation (VNS) combined with rehabilitation was found to be safe and feasible for improving arm function in stroke patients, with all participants completing the therapy despite some serious adverse events related to surgery.

At 90 days post-therapy, patients receiving active VNS showed a significant improvement in upper limb function compared to the control group, with an 88% clinically meaningful response rate, suggesting that VNS may enhance rehabilitation outcomes.

In a randomized controlled study of 30 stroke patients, local vibration applied to the plantar region significantly improved postural stability and reduced fall risk within just 5 minutes of treatment.

The vibration group showed notable enhancements in balance, as measured by the Biodex Balance System, while the control group, which received no actual vibration, did not experience any significant changes.

The study found that neuromodulation through motor imagery and action observation did not enhance the rate of motor adaptation in a complex balance task, and actually resulted in longer adaptation times compared to the control group.

However, the results suggest that individuals with lower proprioceptive participation in balance may benefit from this type of visual neuromodulation, indicating potential for tailored interventions based on balance profiles.
