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 Results may not be published yet.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.

Summary

This study tests if a gentle electrical pulse to the wrist nerve can safely help thinking and memory in people with recent traumatic brain injury. About 30 adults aged 18-64 with moderate injury will receive either real or sham stimulation. The goal is to see if this simple, non-invasive approach is feasible and shows promise for easing cognitive symptoms.

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

Inclusion Criteria: 1. Aged 18-64 years. 2. Admitted within 3 days post-injury with a Glasgow Coma Scale (GCS) score of 9-12 at admission, accompanied by imaging abnormalities. 3. Presence of cognitive dysfunction assessed within 1-week after injury, with a Mini-Mental State Examination (MMSE) score ≤26. 4. Pre-injury Clinical Dementia Rating (CDR) score = 0 as reported by family members. 5. With a pre-injury education of ≥6 years, able to comprehend instructions and cooperate in completing scale assessments, magnetic resonance imaging (MRI), and magnetoencephalography (MEG) examinations. Exclusion Criteria: 1. Requirement for emergent neurosurgical intervention during treatment including surgery, intracranial pressure monitoring device placement, or drainage catheter insertion. 2. Unstable vital signs or hemodynamics, or presence of unstable cardiac, pulmonary, hepatic, renal, or hematopoietic system disorders. 3. Pre-existing central nervous system conditions causing cognitive decline: traumatic brain injury, intracranial infection, brain tumor, epilepsy, stroke, neurodegenerative diseases, carbon monoxide poisoning, and alcohol abuse. 4. Inability to complete assessments or examinations due to severe visual or auditory impairment, severe psychiatric or behavioral disorders, MRI contraindications, and MEG intolerance. 5. Short life expectancy due to critical illnesses. 6. Right forearm with extensive skin lesions or scars, right median nerve injury, brachial plexus injury, cervical spinal cord injury, or intolerance to MNS. 7. Pregnant or lactating women. 8. Participation in other ongoing clinical trials.
