fNIRS for Monitoring Cortical Activity in Stroke Recovery
Functional Near-infrared Spectroscopy (fNIRS) is an Ideal Tool to Monitor Cortical Brain Activity and Understand the Mechanism Underlying Recovery Following Stroke
This clinical trial aims to investigate the mechanisms of brain reorganization underlying motor recovery following end-effector (EE) and exoskeleton (Exo) robot-assisted hand training in individuals with stroke. Using functional near-infrared spectroscopy (fNIRS), the study will (1) investigate brain activation patterns during EE and Exo robot-assisted hand movements in healthy adults and individuals with stroke and (2) examine longitudinal changes in brain activation and motor recovery over a 6-week intervention.
For Part 1, a cross-sectional observational study will be conducted to examine brain activation using fNIRS while participants perform EE and Exo robot-assisted movements. Healthy adults and individuals with stroke will each perform one session of each type of robot-assisted movement.
For Part 2, an evaluator-blinded randomized controlled design will be used. Participants will be stratified based on the level of motor impairment and the side of the brain lesion and then randomly assigned to either the EE or Exo robot-assisted training group. Both groups will receive training 3 times per week, with each session lasting 60 minutes, for a total of 6 weeks. Each session will include 40 minutes of robot-assisted therapy and 20 minutes of functional training.
Outcome assessments will be conducted at four time points: prior to the intervention (baseline), mid-intervention (during weeks 3-4 of the intervention), immediately after the intervention, and at the 3-month post-trial follow-up. These assessments will be used to evaluate motor recovery and longitudinal changes in brain function.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: End-Effector (EE) robot-assisted training group
Robot-assisted therapy (EE system) and functional training
|
Each group will receive intervention 3 times per week, 60 minutes per session, for a total duration of 6 weeks.
The intervention will consist of 40 minutes of robot-assisted therapy and 20 minutes of functional training.
For the robot-assisted therapy, participants will receive training using either the EE or EXO system according to group allocation.
The functional training component will be conducted without robotic assistance and will focus on task-oriented activities to facilitate the transfer of motor learning to functional performance.
