Trial Summary

What is the purpose of this trial?

The loss of movement and walking ability significantly affects quality of life after spinal cord injury. In addition, bladder dysfunction consistently ranks as one of the top disorders affecting quality of life after spinal cord injury. The overall objective of this study is to demonstrate that epidural stimulation may be a method for improving stepping, standing and bladder function in individuals with spinal cord injury. With the use of epidural stimulation, the investigators propose to investigate how well the participant can stand and walk and how well the participant's bladder can store or hold urine as well as void or empty urine. The results of this study may aid in the development of treatments to help individuals with spinal cord injuries that are unable to stand or walk and have impaired bladder function.

Will I have to stop taking my current medications?

The trial requires that participants are not on any current anti-spasticity medication regimen and must not have received botox injections in the prior six months. Other medications are not specified, so it's best to discuss with the trial team.

What data supports the effectiveness of the treatment Epidural Stimulation + Training for Spinal Cord Injury?

Research shows that spinal cord epidural stimulation (scES) can improve bladder control and reflexive voiding efficiency in individuals with spinal cord injury. Additionally, scES has been associated with improvements in motor function and body composition, suggesting its potential to enhance multiple body functions.12345

How does the treatment Epidural Stimulation + Training for Spinal Cord Injury differ from other treatments?

This treatment is unique because it uses electrical stimulation directly on the spinal cord to improve functions like bladder control and mobility, which is different from traditional therapies that may not directly target the spinal cord. It combines this stimulation with specific training exercises to enhance recovery, offering a novel approach to managing spinal cord injury effects.13467

Eligibility Criteria

This trial is for adults over 18 with a stable, non-progressive spinal cord injury (SCI) between T1 and T10. They must be within one year post-injury, unable to stand or walk independently, have bladder dysfunction due to SCI, and not on anti-spasticity meds or received botox in the last six months. Excluded are those ventilator-dependent, with untreated major health issues or psychiatric disorders/drug abuse.

Treatment Details

Interventions

  • Epidural stimulation + Bladder Capacity Training (Procedure)
  • Epidural stimulation + Bladder Voiding Efficiency Training (Procedure)
  • Epidural stimulation + Stand Training (Procedure)
  • Epidural stimulation + Step Training (Procedure)
Trial OverviewThe study tests if epidural stimulation can improve standing, walking, and bladder functions in people with acute SCI. Participants will undergo different training protocols: Bladder Capacity Training, Bladder Voiding Efficiency Training, Step Training or Stand Training alongside the epidural stimulation.
Participant Groups
2Treatment groups
Experimental Treatment
Group I: LocomotionExperimental Treatment2 Interventions
Participants will receive 160 locomotor training sessions with epidural stimulation. These sessions may occur once a day (stand and step will alternate days) or twice a day (stand and step on the same day) as recommended by the study physician. Participants will train 5 days per week and each session will last between 1 to 1.5 hours.
Group II: Bladder+LocomotionExperimental Treatment4 Interventions
Participants will receive 80 sessions of bladder training alone followed by 80 sessions of locomotor training sessions with epidural stimulation. They will be asked to continue with your bladder training once you start locomotor training. Locomotor Training sessions may occur once a day (stand and step will alternate days) or twice a day (stand and step on the same day) as recommended by the study physician. Participants will train 5 days per week and each session will last between 1 to 1.5 hours.

Findings from Research

Epidural electrical stimulation (EES) combined with task-specific training may negatively affect bladder function in individuals with spinal cord injury, as one participant experienced increased urinary incontinence and worsening bladder compliance after 12 months of EES training.
On a positive note, EES appears to enhance body composition, as one participant gained 9.1 kg of lean mass and improved fat distribution, suggesting that EES can be beneficial for muscle activation and body composition in individuals with chronic paralysis.
Impact of long-term epidural electrical stimulation enabled task-specific training on secondary conditions of chronic paraplegia in two humans.Beck, L., Veith, D., Linde, M., et al.[2021]
Spinal cord epidural stimulation (scES) has shown promise in improving bladder control in individuals with chronic, motor complete spinal cord injury, as demonstrated in a study involving one participant over four months and later confirmed in four additional participants.
The optimal stimulation frequency for enhancing reflexive bladder emptying was identified as 30 Hz, indicating that scES can effectively reduce post-void residual volumes and improve urological function after spinal cord injury.
Lumbosacral spinal cord epidural stimulation improves voiding function after human spinal cord injury.Herrity, AN., Williams, CS., Angeli, CA., et al.[2019]
Spinal cord epidural stimulation (SCES) not only aids in facilitating walking but also improves cardiovascular autonomic regulation and reduces spasticity in a 27-year-old male with a complete spinal cord injury, as shown in assessments conducted 15 weeks apart.
The study demonstrated that SCES can stabilize blood pressure during postural changes and significantly reduce muscle spasticity, suggesting that a single SCES configuration can provide multiple functional benefits, which may enhance its clinical application.
