Telerehabilitation and Biomarkers of Recovery After Stroke in Brazil (TR-BR-1)

June 9, 2026 updated by: Taiza G. S. Edwards, PhD, University of Sao Paulo

Telerehabilitation and Biomarkers of Functional Recovery After Stroke in Brazil: TR-BR-1 Clinical Trial

The purpose of this research study is to provide preliminary evidence of whether telerehabilitation targeting arm movement, when added to usual care, improves arm function and reduces global disability after stroke, compared to usual care alone in Brazil. Evaluate the safety and feasibility of telerehabilitation in the Brazilian context. Explore the clinical, neuroimaging, neurophysiological, and economic factors that influence telerehabilitation efficacy in functional recovery following stroke.

Detailed Description

This is a two-arm phase II randomized controlled trial with blinded outcome assessment. A total of 20 post-stroke participants will be randomized to either telerehabilitation added to usual care (TR+UC) or usual care alone (UC). The primary outcome measure is the Action Research Arm Test (ARAT), which assesses upper extremity motor function. Secondary measures will include feasibility and intervention-related outcomes.

Study participation will span approximately 4 months and includes 6 in-person assessment visits. At these visits, participants will complete a battery of assessments, including upper extremity motor function tests, resting-state functional electroencephalography (EEG), and a single magnetic resonance imaging (MRI) scan of the brain. Participants assigned to the TR+UC group will receive structured arm motor training consisting of 36 sessions of prescribed exercises, interactive games, and stroke education delivered over 6 weeks at a frequency of 6 days per week, with each session lasting approximately 70 minutes. TR+UC participants will continue all usual care concurrently. Participants in the UC group will continue all therapies recommended by their medical team without participating in telerehabilitation.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Usual Care
Participants in the usual care group will receive no TR, but will continue with the recommendations made by their care team.
Usual care rehabilitation refers to the recommendations made by their care team.
Active Comparator: Telerehabilitation + Usual Care
In addition to the usual care, patients will receive 36 telerehabilitation sessions targeting arm motor function in addition to their usual care. TR consists of 70 minutes/day of activities targeting arm function, 6 days/week for 6 weeks. Half of these sessions are supervised by a licensed therapist, and the other half are done independently.
