Robotic arm for upper limb rehabilitation after stroke

Mobile Electromyography (EMG)-Driven Exoneuromusculoskeleton for Upper Limb Rehabilitation After Stroke

Not applicable Interventional The Hong Kong Polytechnic University · NCT03752775

This study is testing a new robotic arm to see if it can help stroke patients recover their arm movement better than regular therapy.

What this trial studies

This study evaluates a new robotic arm designed for multi-joint coordinated rehabilitation of the upper limb in stroke patients. The mobile exo-neuro-musculo-skeleton integrates features of exoskeletons, soft robotics, and neuromuscular electrical stimulation to provide a noninvasive and comfortable rehabilitation experience. Patients with both subacute and chronic strokes will participate, receiving device-assisted therapy compared to conventional rehabilitation methods. The effectiveness of this innovative approach will be assessed through pre- and post-treatment clinical evaluations.

Who should consider this trial

Good fit: Ideal candidates include individuals who have experienced a stroke within the last six months and have specific motor function limitations.

Not a fit: Patients who are currently pregnant, have language deficiencies, or do not meet the inclusion criteria will not benefit from this study.

Why it matters

Potential benefit: If successful, this device could significantly improve motor function in stroke patients, enhancing their rehabilitation outcomes.

How similar studies have performed: Other studies have shown promise with robotic-assisted rehabilitation approaches, suggesting potential success for this novel device.

Inclusion Criteria:

For the subacute groups:

* Two weeks after the onset of stroke, however less than 0.5 year
