Hybrid robot and electrical stimulation for stroke rehabilitation

Assessment Followed by Home-based Hybrid Robot + FES Rehabilitation Post-stroke

Phase1; Phase2 Interventional University of Maryland, Baltimore · NCT04550728

This study is testing a new way to help stroke survivors recover by using a robot for stretching along with electrical stimulation to see if it improves their movement and muscle strength.

What this trial studies

This clinical trial investigates a novel rehabilitation approach for stroke survivors that combines robot-guided stretching with functional electrical stimulation (FES) to enhance motor recovery. The study aims to improve joint range of motion, reduce spasticity, and increase muscle force output through a hybrid system that integrates robotic training and FES. Participants will be randomly assigned to receive either ankle robot training alone or in combination with FES, primarily in a home-based setting. The goal is to translate advanced rehabilitation technologies from the lab to everyday use for stroke patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-85 who are at least six months post-stroke and can ambulate at least 10 meters with or without assistance.

Not a fit: Patients with severe pain in the paralyzed lower limb or those with implanted electronic devices may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance motor recovery and functional independence for stroke survivors.

How similar studies have performed: While the combination of robotic training and FES is a novel approach, similar studies have shown promise in enhancing rehabilitation outcomes for neurological conditions.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Age 18-85;
* Able to ambulate at least 10 meters without human assistance, with or without an assistive device
* ≥ 6 months post stroke;
* having a caregiver to assist in training at home.

Exclusion Criteria:

* having expressive and receptive aphasia;
* an inability to follow multi-step commands;
* enrolled in another lower limb rehabilitation program;
* having severe pain in the paralyzed lower-limb;
* \>30º ankle plantar flexion contracture;
* Having implanted electronic device such as a pacemaker, spinal cord, or deep brain stimulator because FES may potentially interfere with their functions.
