What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a treatment called PoNS Therapy (Portable Neuromodulation Stimulator) to assist people who have had a stroke. The main goal is to determine if PoNS Therapy is safe and can improve walking and balance. The trial also examines how the therapy affects quality of life and whether it reduces the risk of falling. Individuals who experienced a stroke more than six months ago and have difficulty walking might be suitable for this study. As an unphased trial, this study provides 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. However, it does exclude participants using certain stimulation devices or those who have had neurostimulation therapy recently.

What prior data suggests that PoNS therapy is safe for stroke survivors?

Research has shown that PoNS Therapy has undergone safety testing in several studies. One study included 159 stroke survivors and assessed the therapy's safety and effectiveness. Although specific safety details are not provided, multiple trials have reviewed the treatment. The PoNS device is non-invasive and stimulates nerves on the tongue to aid balance and walking. Its testing in several trials and progress toward FDA approval for other uses suggest it is generally well-tolerated. However, like any treatment, some side effects may occur. Always consult a doctor to determine if it is suitable. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about PoNS Therapy for stroke survivors because it offers a unique approach compared to traditional rehabilitation methods like physical therapy and medication. Unlike these standard treatments, PoNS Therapy uses translingual neurostimulation, a novel method that involves stimulating the brain through the tongue to enhance neural recovery. This approach could potentially speed up rehabilitation and improve motor function more effectively than conventional therapies. By targeting the brain's plasticity directly, PoNS Therapy holds promise for better and faster recovery outcomes for stroke patients.

What evidence suggests that PoNS Therapy is effective for stroke survivors?

Research has shown that PoNS Therapy, studied in this trial, may help stroke survivors enhance their balance and walking. In studies with 159 participants, the treatment led to noticeable improvements in their walking and balance. PoNS Therapy uses neurostimulation, sending signals to the brain to aid physical recovery. Participants have responded well to the treatment, and plans exist to submit it to the FDA for approval based on these positive results. Overall, the therapy appears to be a promising option for aiding stroke patient recovery. ^{1 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for chronic stroke survivors who are experiencing issues with walking and balance. Participants should be able to commit to the study duration and follow-up requirements. Specific eligibility details aren't provided, but typically, trials exclude individuals with conditions that could interfere with the treatment or skew results.

Published Research Related to This Trial

Vagus nerve stimulation (VNS), both invasive and non-invasive, significantly improves motor function and reduces motor impairment in stroke patients, based on a systematic review and meta-analysis of multiple studies.

The study found no significant difference in adverse events between VNS and control groups, suggesting that VNS is a safe intervention for enhancing recovery in stroke patients.

Transcutaneous electrical nerve stimulation (TENS) significantly improved activities of daily living (ADL) in stroke patients, with notable enhancements in various tasks such as feeding, walking, and dressing, compared to a placebo group.

The study involved 60 stroke patients over 40 sessions (8 weeks), and while both groups showed improvements, the active TENS group demonstrated greater overall functional gains and reduced spasticity, although initial differences in disability levels may affect the results' interpretation.

Recent advances in stroke recovery therapies, including activity-based therapies, brain stimulation techniques, and robotics-assisted therapies, aim to enhance neural plasticity and improve rehabilitation outcomes for stroke patients.

A multidisciplinary approach and individualized treatment plans, supported by large-scale clinical trials, are essential for maximizing recovery and addressing the diverse needs of stroke survivors.

Despite various treatments available for improving blood flow after a stroke, there is a significant need for effective rehabilitation methods to enhance neurological recovery, as most stroke survivors with motor impairments do not fully regain their previous functional abilities.

Emerging rehabilitation therapies, such as selective serotonin reuptake inhibitors, constraint-induced movement therapy, noninvasive brain stimulation, mirror therapy, and motor imagery, show promise in restoring motor function and improving the quality of life for stroke survivors.

Deep brain stimulation (DBS) shows promise in managing post-stroke maladaptive responses such as pain, dystonia, dyskinesias, and tremor, based on a comprehensive literature review.

While evidence for DBS improving motor deficits after stroke is limited, some studies suggest that targeting the posterior limb of the internal capsule may help improve weakness (paresis) in certain cases, indicating a need for further research in this area.

In a study of 33 stroke patients and 19 healthy volunteers, it was found that stroke significantly reduces the generation of movement-preparatory low-frequency oscillations (LFOs) in the brain, which are crucial for motor control.

As patients recovered over 1 to 3 months, the re-emergence of LFOs correlated with improvements in motor function, suggesting that therapies aimed at restoring these signals could enhance recovery after a stroke.
