What You Need to Know Before You Apply

What is the purpose of this trial?

This study is a pilot clinical trial to explore the efficacy of transcutaneous spinal cord stimulation (TCSCS) (proof-of-concept) in mitigating crucial autonomic dysfunctions that impact the health-related quality of life of individuals with spinal cord injury (SCI).

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are taking oral baclofen over 60mg or have an intrathecal baclofen pump, you may not be eligible to participate.

Is spinal cord stimulation generally safe for humans?

Spinal cord stimulation (SCS) is generally considered safe, with few reported complications, even in challenging environments like military settings. However, rare complications such as spinal cord compression and overstimulation leading to injury have been documented, indicating the need for careful monitoring and patient education. ^{1 2 3 4 5}

How is the TESCoN device treatment for spinal cord injury different from other treatments?

The TESCoN device treatment for spinal cord injury is unique because it involves lumbosacral and thoracic stimulation, which may offer a novel approach compared to traditional spinal cord stimulation methods. Unlike standard treatments that often require multiple cables, this device potentially simplifies the process by using fewer cables while still providing effective stimulation. ^{6 7 8 9 10}

What data supports the effectiveness of the treatment TESCoN device - Lumbosacral stimulation, TESCoN device - Thoracic stimulation for spinal cord injury?

Research shows that combining different types of spinal cord stimulation, like cervical and lumbar, can improve voluntary control of movement in people with chronic spinal cord injuries. Additionally, transcutaneous spinal cord stimulation has been found to enhance muscle activity and coordination, suggesting it can help improve motor function in those with spinal cord injuries. ^{11 12 13 14 15}

What Are the Treatments Tested in This Trial?

Interventions

• TESCoN device - Lumbosacral stimulation
• TESCoN device - Thoracic stimulation

Trial Overview The study tests the effectiveness of a noninvasive device called TESCoN for thoracic and lumbosacral stimulation to improve autonomic functions impaired by spinal cord injuries. It's a pilot trial to see how well it works to enhance life quality.

How Is the Trial Designed?

Group I: Group 2- Lumbosacral stimulation Experimental Treatment 1 Intervention

Participants will receive 8 weeks TCSCS at the lumbosacral spinal cord levels.

Group II: Group 1 - Thoracic stimulation Experimental Treatment 1 Intervention

Participants will receive 8 weeks TCSCS at the mid/low thoracic spinal cord levels.

Published Research Related to This Trial

Transspinal stimulation (TSS) is a promising non-invasive neuromodulation technique that can activate spinal cord circuits to improve motor function in individuals with spinal cord injury, as evidenced by a review of 34 studies.

The review highlighted that multisite electrode placements generally resulted in better motor responses compared to single-site placements, suggesting that optimizing stimulation parameters is crucial for enhancing treatment outcomes, although further controlled studies are needed.

Spinal cord stimulation (SCS) is effective in improving pain relief, sleep quality, and functional activities in patients with chronic pain, as shown by a survey of 30 patients who reported positive outcomes after receiving different SCS devices.

While there were no significant differences in pain relief and sleep improvement among the three SCS device manufacturers (Medtronic, Advanced Bionics, and ANS), the Advanced Bionics group showed less functional improvement compared to the other two groups, suggesting that device technology may influence certain outcomes.

Spinal cord stimulators (SCS) and peripheral nerve stimulators (PNS) are effective treatments for chronic pain, enabling many military service members to return to work and daily activities.

Despite potential environmental and occupational hazards faced by military personnel, the risk of complications from SCS and PNS devices remains low, indicating their safety in these challenging conditions.

In a study of 69 patients with implanted spinal cord stimulators (SCSs) who underwent 78 MRI scans, the overall adverse event rate for off-label MRI use was low at 9.72%, with no serious adverse events reported.

All reported clinical adverse events were minor and resolved, suggesting that the benefits of MRI for pain management in patients with older SCS models may outweigh the associated risks.

In a study examining spinal cord stimulation parameters, pulse width (Pw) significantly influenced stimulation thresholds, but did not affect the coverage or quality of paresthesia experienced by patients.

Frequency (F) adjustments were found to be crucial for enhancing the coverage of painful areas and improving the quality of paresthesia perception, suggesting that frequency management is key for effective pain relief.

The Evoke® spinal cord stimulation (SCS) device uses real-time feedback from the spinal cord to adjust stimulation levels, which is a unique feature not found in other commercially available SCS devices.

A systematic review of data over 24 months shows that the Evoke system is both safe and effective for treating chronic intractable pain, providing strong evidence for its clinical use.
