What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a device that gently stimulates a nerve in the ear (taVNS) is safe and practical when used during arm and hand therapy for people with chronic incomplete cervical spinal cord injury. Twelve adults will receive 18 therapy sessions over six weeks, followed by a home exercise program. The main goal is to check for side effects and see if participants can stick with the treatment.

What this could mean

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

Active substance
transcutaneous auricular vagus nerve stimulation (taVNS) device
What this could lead to
If successful, this could point toward a new way to improve arm and hand function after spinal cord injury by combining nerve stimulation with rehabilitation.
What could go wrong
This is a very small, early-stage safety study with only 12 participants. It is not designed to prove whether the treatment works, and results may not apply to a broader population.

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 12 people

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

Started

Aug 2025

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * diagnosis of traumatic incomplete (AIS B-D) cervical spinal cord injury (C8 and above) * at least 12 months post-traumatic SCI but less than 10 years post-SCI * demonstrate some residual movement in the upper limb (e.g., able to perform pinch movement with thumb and index finger sufficient to grip small objects such as marble) Exclusion Criteria: * non-traumatic SCI * recent ear trauma and skin lesions at the site of stimulation, such as sunburn, cuts, and open sores, * facial or ear pain, * allergic reaction to adhesives and electrodes, * any current or past history of cardiovascular disorders, * intracranial metal implants, pacemakers, * concomitant clinically significant brain injury, * receiving medication that may significantly interfere with the actions of VNS on neurotransmitter systems at study entry * If there is a plan for alteration in upper-extremity therapy or medication for muscle tone during the course of the study; * medical or mental instability; * pregnancy or plans to become pregnant during the study period
