Epidural Spinal Cord Stimulation for Respiratory Recovery in Cervical SCI
China20 participantsStarted 2026-06-01
Plain-language summary
This multicenter, single-arm exploratory IIT evaluates epidural spinal cord electrical stimulation (ESCES) in 20 adults with C1-C5 SCI and respiratory failure. Participants receive ESCES plus standard care; electrodes are implanted at C3-C5 with daily individualized stimulation. Primary outcomes: Edi peak, change of Edi peak and frequency. Secondary: tidal volume, maximal inspiratory pressure, NVE, NME, diaphragm ultrasound, cough strength, 90-day ventilator-free days, ICU stay, and survival. This is the first systematic ESCES study for SCI-related respiratory failure, aiming to provide preliminary safety/efficacy data for future RCTs.

Inclusion criteria
. Age between 18 and 75 years, with BMI \<30 kg/m².
. Cervical SCI involving levels C1-C5 for at least 2 weeks.
. Respiratory failure defined by one or more of the following:

Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Peak electrical activity of the diaphragm (Edi peak)
Timeframe: up to 1 month
2
Diaphragmatic electrical activity frequency (Edi frequency)
. Active infection at the planned electrode implantation site, severe systemic infection, or existing implanted neurostimulation devices.
. Respiratory failure primarily caused by severe pneumonia, pulmonary contusion, pneumothorax, hemothorax, chronic obstructive pulmonary disease, or requirement for home oxygen therapy within the previous 6 months.
. New York Heart Association (NYHA) class III or IV heart failure or implanted cardiac pacemaker.
. Severe hepatic or renal dysfunction (Child-Pugh class C liver disease or estimated glomerular filtration rate ≤30 mL/min/1.73 m²) or dialysis dependence.
. Generalized seizures, traumatic brain injury, intracranial hypertension, intracranial aneurysm with Glasgow Coma Scale score ≤12, or neuromuscular disorders affecting respiratory function.
. Expected survival \<72 hours or refusal of life-sustaining treatment.
. Pregnancy or breastfeeding.
. Any other condition considered by the investigator to make study participation inappropriate.
