This clinical trial compares two types of robotic hand rehabilitation-brain wave (EEG)-timed therapy versus simple repetitive therapy-to see which is more effective for recovering hand function in patients with chronic stroke. Participants will be randomly assigned to either group and will attend sessions using a wearable robotic hand device while wearing an EEG cap. In the EEG-timed group, the robot assists hand movements when participants successfully imagine moving and create specific brain signals, whereas in the repetitive group, the robot moves the hand automatically at set intervals. Both groups will receive a matched dose of robotic training to ensure a fair comparison of how the brain and hand function respond to the therapy.

Exclusion Criteria:
Note: Patients with an MMSE score of 15 or below may still be included if the Principal Investigator (or a delegated physician) determines that they have the capacity to perform the tasks and provide .
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Device: EEG-Timed Robot Operation
Device: Repetitive Robotic System
A wearable hand robot that activates in real-time when the patient successfully generates a specific brain signal (ERD) during movement observation and motor imagery.
A wearable robotic hand that provides repetitive hand opening and closing movements at fixed intervals, without requiring EEG signal triggering.
Change in Event-Related Desynchronization (ERD) During Motor Tasks
Event-Related Desynchronization (ERD) is continuously measured using multi-channel EEG over the sensorimotor cortex while participants perform action observation and motor imagery (AO+MI) tasks. ERD represents the decrease in EEG power in specific frequency bands (e.g., mu or beta rhythms), which reflects the level of cortical activation. A greater magnitude of ERD indicates stronger and more active neurophysiological engagement of the motor cortex.
Time frame: Baseline, Week 2, Week 4, and Week 6
Change in Upper Extremity Motor Function Assessed by the Fugl-Meyer Assessment (FMA-UE)
The Fugl-Meyer Assessment for Upper Extremity (FMA-UE) is a stroke-specific, performance-based index designed to assess motor impairment. It evaluates movement, coordination, and reflex action of the shoulder, elbow, forearm, wrist, and hand. The total FMA-UE score ranges from 0 to 66. Higher scores indicate better motor function and less impairment.
Time frame: Baseline, Week 2, Week 4, and Week 6
Change in Upper Extremity Motor Performance Assessed by the Action Research Arm Test (ARAT)
The Action Research Arm Test (ARAT) is an observational, performance-based measure used to assess upper extremity function, specifically focusing on grasping, gripping, pinching, and gross movement. The total score ranges from 0 to 57. Higher scores indicate better arm and hand motor performance and greater upper limb dexterity.
Time frame: Baseline, Week 2, Week 4, and Week 6

Start is estimated for Mar 2026; primary completion for Mar 2028, 24 months later.
Of 3,108 non-industry interventional studies with no phase under Stroke, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 46. This study's planned 24 months is close to that.
Counting every sponsor, half of 3,252 studies reached it within 23 months; a quarter within 10 and three quarters within 46.
