NCT ID NCT07306052

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 Results may not be published yet.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

Summary

This study tests a device that sends electrical pulses to the spinal cord, combined with daily rehab, to help people with chronic spinal cord injury regain walking ability. Twelve participants will receive the implant and be followed for over a year. The goal is to see if the approach is safe and improves walking and independence.

Inclusion Criteria: * Age between 16 and 70 years. * Diagnosed with traumatic spinal cord injury for ≥ 6 months and ≤ 60 months. * American Spinal Injury Association Impairment Scale (AIS) grade B-D. * Spinal cord injury level above T10; * Walking Index for Spinal Cord Injury II (WISCI II) score ≤ 13. * Completion of a standard conventional rehabilitation program prior to enrollment. * Preserved upper limb function sufficient for self-propelling a manual wheelchair. * Sitting balance grade ≥ 1. * Ability to elicit clear electromyographic responses in lower limb muscles (e.g., rectus femoris, biceps femoris, gastrocnemius, tibialis anterior) upon transcutaneous electrical spinal cord stimulation at the T12-L1 vertebral levels. * Willingness to voluntarily participate, and commitment to compliance with all necessary postoperative rehabilitation, assessments, and follow-up visits. Exclusion Criteria: * History of myocardial infarction or stroke within the past 6 months. * Diagnosis of psychiatric disorders with active suicidal ideation or risk. * Current pregnancy or planned pregnancy during the study period. * Bleeding tendency or coagulopathy (prothrombin time ≥18 seconds). * History of alcohol or substance abuse or dependence. * Intellectual disability, cognitive impairment, or personality disorders. * Other chronic medical conditions that may interfere with rehabilitation (e.g., unhealed severe fractures, hepatic or renal failure, severe anemia, etc.). * Implantation of cardiac pacemakers, cardioverters, or defibrillators. * Any other condition deemed inappropriate for participation by the investigators.
