What is the purpose of this trial?

This trial tests two types of electrical stimulation to treat lumbosacral radiculopathy, a condition causing pain from a pinched nerve in the lower back. It compares a new direct current device, the Neubie Direct Current Electrical Stimulation Device, with a traditional TENS unit to determine which more effectively reduces pain and improves daily function. Individuals diagnosed with lumbosacral radiculopathy who can attend weekly sessions for six weeks may be suitable candidates. The trial will assess pain levels, functional ability, and overall satisfaction with the treatment. As an unphased trial, this study provides a unique opportunity to explore innovative treatments and contribute to medical advancements.

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 these electrical stimulation methods are safe for treating lumbosacral radiculopathy?

Research has shown that the Neubie Direct Current Electrical Stimulation Device is generally safe. In studies, participants using the Neubie device experienced significant improvements in pain relief and movement over six weeks, indicating good tolerance.

The type of electrical stimulation used by the Neubie device is considered safe and minimally invasive. It has been successfully used to manage long-term pain, suggesting a strong safety record.

No specific reports of negative effects appear in the available data. However, because this technology is not as widely used as traditional methods like the TENS unit, less information exists about its long-term effects. Overall, it seems to be a promising and safe option for those considering electrical stimulation therapy. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Neubie Direct Current Electrical Stimulation Device for pinched nerves because it offers a new approach by delivering direct current stimulation, which is different from the alternating current used in traditional treatments like Transcutaneous Electrical Nerve Stimulation (TENS). This direct current aims to enhance muscle re-education and nerve repair more effectively. Unlike other treatments that rely on indirect stimulation, the Neubie targets the nervous system directly, potentially speeding up recovery and improving outcomes for patients with pinched nerves.

What evidence suggests that this trial's electrical stimulation methods could be effective for treating lumbosacral radiculopathy?

Research has shown that the Neubie Direct Current Electrical Stimulation Device, which participants in this trial may receive, can help reduce pain and improve movement for people with a pinched nerve in the lower back. Some patients have experienced better movement and increased energy after using this device. This type of electrical stimulation, such as the Neubie, is considered safe and can help manage long-term pain. Although direct current stimulation is not as commonly used as other methods, early results are promising. It aims to improve pain levels, mobility, and overall satisfaction. ^{1 2 3 4 6}

Published Research Related to This Trial

A study found that repetitive direct current (DC) stimulation on peripheral motor nerves caused significant myelin and axon degeneration, indicating a risk of permanent nerve damage and muscle paralysis.

In contrast, previous research showed that pulsed current stimulation was equally effective but much safer than DC stimulation, suggesting that pulsed current may be a better option for clinical use.

Using a finite element model, researchers found that placing electrodes epidurally (on the surface of the spinal cord) significantly increases the intensity of electric fields compared to placing them outside the spine, which could enhance therapeutic effects for spinal cord injury.

Optimizing electrode design, such as using a single large band electrode, can produce effective electric fields with low current density, potentially minimizing the risk of tissue damage while improving the efficacy of low-intensity direct current stimulation.

Inductive stimulation of the frog sciatic nerve and gastrocnemius muscle was not successfully achieved using standard techniques and EMF intensities, suggesting limitations in current methods for nerve stimulation.

When stimulation did occur, it was likely due to capacitive coupling rather than pure inductive effects, with maximum induced current densities estimated between 10 to 30 mA/cm2, indicating a need for further investigation into effective stimulation techniques.

Electrical stimulation of peripheral nerves has been used for over 30 years to treat intractable pain, but its application has been inconsistent due to challenges in defining proper use and standardizing techniques.

Recent advancements, such as percutaneous wire electrode methods, offer a minimally invasive approach to peripheral nerve stimulation, particularly for complex regional pain syndrome (CRPS) and other painful mononeuropathies.

The Safe Direct Current Stimulator (SDCS) is a new device that allows for safe direct current stimulation of neural tissue, overcoming the limitations of traditional methods that only use alternating biphasic current pulses.

The updated SDCS2 design improves upon the original SDCS1 by providing continuous stimulation without interruptions and is compact enough for use in chronic animal studies, making it a promising tool for both exciting and inhibiting neurons.

In a study involving 30 patients with painful diabetic neuropathy, pulsed-dose electrical stimulation using stocking electrodes did not show greater efficacy in reducing pain or sleep disturbance compared to a control group with minimal current.

Both the active treatment and control groups experienced similar reductions in pain and sleep disturbance scores, indicating that the pulsed electrical stimulation may not be an effective treatment for this condition.

In a controlled study simulating clinical procedures, pulsed current stimulation for 5 and 25 seconds caused nonspecific inflammatory changes similar to nonstimulated nerves, indicating it does not produce harmful neuropathologic effects.

In contrast, direct current stimulation led to frequent myelin degeneration and occasional axon degeneration, suggesting that pulsed current is a safer alternative while maintaining effectiveness.

Electrical stimulation has a long history in pain treatment, gaining scientific credibility with the Gate Control Theory introduced in 1965, which explained how nerve stimulation can help manage pain.

Today, peripheral nerve stimulation is used effectively for various painful conditions, evolving from treating major nerves to targeted subcutaneous stimulation for specific neuropathic pain areas.
