Feasibility Study of Passive Robots for Stroke Rehabilitation

This study is exploring a new way to help people recover arm and hand movement after a stroke. It uses two devices, SepaRRo and NeuRRoFES, which are designed to assist or resist your arm movements during exercises. NeuRRoFES also provides neuromuscular stimulation (gentle electrical pulses to muscles) during these activities. The goal is to see if these low-cost, non-motorized devices are practical and effective for stroke rehabilitation, potentially for use at home. Researchers are looking for 4 participants, aged 18 to 75, who have had a stroke and do not have major sensation problems or severe joint limitations. The study will measure how well the devices work and how easy they are to use immediately after the intervention.

Study design
This is an interventional study with an unspecified phase, aiming to enroll 4 participants. It is designed to evaluate the feasibility of using passive devices for stroke rehabilitation.
What's involved
Participants will perform functional movements with their arms using the SepaRRo and NeuRRoFES devices. Biofeedback may be provided during training.
Compensation
Not stated in the trial record.
Follow-up
Feasibility will be measured immediately following the last session of intervention.
