Summary

This study is testing whether combining two types of electrical stimulation with a robotic arm trainer can help people who had a stroke at least six months ago improve their arm movement. 65 participants will receive 20 sessions over 4-7 weeks. The goal is to see if this approach can improve motor function and reduce muscle stiffness.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: Electrical stimulation (trans-spinal and neuromuscular) combined with a rehabilitation robot
What this could lead to: If it works, this could point toward a more effective way to restore arm movement after a stroke, improving daily life for survivors.
What could go wrong: This is a small, early-stage study with no control group, so results may not be conclusive. The therapy is intensive and may not work for everyone.

Inclusion Criteria: * Subjects in the chronic stage (start from 6 months after the onset of stroke) with a pure unilateral motor paresis after a stroke (ischemic or hemorrhagic); * Sufficient cognition to follow simple instructions as well as understand the content and purpose of the experiment (Mini-Mental State Examination (MMSE) score\>23); * Be able to sit up for 60 minutes (with or without assistance); * Muscle strength graded from 1 to 3 in biceps brachii, triceps brachii, extensor carpi radialis, flexor carpi radialis, and abductor pollicis brevis in the affected side. * The voluntary electromyographic signals of the wrist extensor and wrist flexor muscle groups can be detected. Exclusion Criteria: * Patients with secondary stroke; * Severe dysphasia (either expressive or comprehensive) with inadequate communication; * Any additional medical or psychological condition affecting their ability to comply with the study protocol; * History of other neurological disease, psychiatric disorder, including alcoholism and substance abuse; * currently pregnant; * epilepsy; * pacemaker implantation or deep brain stimulation; * involved in drug studies, other clinical trials, or concurrent medication/occupational/physical treatments on the upper limb; * skin disease at the area of the electrodes; * High hypertension and cannot maintain normal blood pressure despite daily intake of antihypertensive medication.
