NCT ID NCT05960448

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether transcutaneous spinal cord stimulation (TSCS) — a gentle electrical current applied through the skin — can help veterans with chronic spinal cord injury (SCI) better regulate blood pressure during exercise and cold exposure. Participants will receive both active and sham stimulation while using an arm bike or sitting in a cool room, and researchers will measure exercise endurance, heart rate recovery, core temperature, and thermal comfort. The goal is to see if TSCS can improve autonomic function, which often becomes impaired after SCI, leading to issues like orthostatic hypotension.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Transcutaneous spinal cord stimulation (TSCS) — electrical stimulation delivered through the skin to the spinal cord, compared to a sham (placebo) version.
What this could lead to
If effective, TSCS could offer a non-invasive way to help people with spinal cord injuries maintain blood pressure and tolerate exercise and temperature changes better.
What could go wrong
This is a small early-stage crossover study with no expected long-term benefit. Results may not apply broadly, and the stimulation may not improve outcomes beyond placebo.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 20 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jul 2023

Expected to finish

Jul 2026

An estimate. End dates often move.

Lead sponsor

A government agency

The lead sponsor is a US federal agency other than the NIH.
