About this study
Official title: Feasibility and Effectiveness of Home-based Telerehabilitation Program for Recovery of Upper Limb Functions in Incomplete Spinal Cord Injury
This study evaluates a remotely supervised, home-based therapeutic program to improve upper-limb voluntary movement in adults with tetraplegia caused by incomplete spinal cord injury (iSCI).
Read the detailed description
Spinal Cord Injury (SCI) has been associated with serious reduction in functional independence. Despite compelling evidence that treatment intensity has a profound effect on motor recovery only a small fraction of SCI population are able to receive intensive in-clinic treatment. Difficulty traveling to the clinic, poor adherence to assignments and high cost are limiting factors. Currently, telerehabilitation programs are emerging as an alternative effective method of delivery for rehabilitation services. The literature and our preliminary findings support the model that augmentation of activity in spared corticospinal tract (CST) axons is a critical mechanism of motor improvement, and furthermore that CST activity can be increased by repetitive motor training and by electrical stimulation of the primary motor cortex (M1). However, there is still lack of knowledge on safety, feasibility and efficacy of remotely- supervised home-based therapy programs that incorporates non-invasive brain stimulation and high intensity repetitive arm exercises. To address these questions, 36 adults (above 18 years) with cervical SCI will be randomly assigned to two groups in a 2:1 ratio (active stimulation group, n=24 vs control group, n=12) and receive daily treatment, 10 sessions, over 2-weeks. The anodal tDCS will be applied over primary motor cortex (M1) at an intensity of 2mA for 20 minutes and proceed with 60 minutes of repetitive arm and hand training. Primary outcome measure is change in Graded and Redefined Assessment of Strength, Sensibility, and Prehension (GRASSP) from baseline to immediately after treatment and 4-weeks follow-up. The session will be supervised in real-time via videoconferencing.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Active tDCSDevice
Anodal tDCS will be placed over the primary motor cortex and delivered at 2mA for 20 minutes. Immediately after stimulation ceases, participants will continue with unilateral repetitive arm and finger exercises for 60 minutes. Exercise difficulty will gradually be increased and adjusted per participant's tolerance.
Sham tDCSDevice
Anodal tDCS will be placed over the primary motor cortex and delivered at 2mA for 20 minutes. Immediately after stimulation ceases, participants will continue with unilateral repetitive arm and finger exercises for 60 minutes. Exercise difficulty will gradually be increased and adjusted per participant's tolerance.

Questions about this trial
What is this clinical trial studying?
A study testing Active tDCS in people with Incomplete Spinal Cord Injury, run by The University of Texas Health Science Center, Houston at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 20 Apr 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Arm and Hand Function as Assessed by Score on the Graded Redefined Assessment of Strength, Sensibility and Prehension (GRASSP) (time frame: Baseline). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2025.
