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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 pilot study tests whether a neurofeedback device can reduce light sensitivity in 36 Veterans who have had a mild traumatic brain injury at least 6 months ago. The device uses low-intensity electrical pulses to train brain activity. Researchers will also use MRI scans to see how the brain changes. The goal is to see if the approach is feasible and acceptable, not yet to prove it works.

What this could mean

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

Active substance
Micro Current Neurofeedback Device using Low-Frequency Pulse-Based Transcranial Electrical Stimulation (LIP-tES)
What this could lead to
If successful, this could provide a new, non-drug way to reduce light sensitivity in people with mild traumatic brain injury.
What could go wrong
This is a very small pilot study (36 people) testing feasibility, not effectiveness. The device may not work better than a sham, and results may not apply to everyone.

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 36 people

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

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

Inclusion Criteria: * Ages 18-65 * Documented history of mTBI at least 6 months prior to initial study visit * Documented symptoms of photosensitivity * Eye exam within the last 12 months documenting best-corrected acuity of 20/20 or better, normal pupillary function, color vision, no abnormalities on OCT scan, and normal Humphrey Visual Field test Exclusion Criteria: * History of strabismus or amblyopia * Significant ocular media opacity that could reduce the amount of light entering the pupil in one or both eyes * Previous or current history of retinal or optic nerve pathology in one or both eyes * History of stroke and/or visual neglect * History of neurodegenerative disease (e.g., Parkinson's, multiple sclerosis) * History of epilepsy or seizures * History of motor tics * Current use of medications or substances that may severely affect pupillary response and/or increase photosensitivity * Individuals with impaired decision-making capacity * Illiterate or no English language proficiency
