Overview

The investigators have developed a novel robot-guided stretching under intelligent control and combine it with active movement training, which helped increase joint ROM, reduce spasticity and joint stiffness, increase muscle force output, and improve locomotion. However, for stroke survivors with sensorimotor impairment, their peripheral muscle may not sufficiently be recruited. Functional electrical stimulation (FES), has been shown its advantage to activate the peripheral muscles for people with neurological conditions. The investigators thus make a hybrid robot-FES rehabilitation system, combining the advantage of robot and FES technologies for stroke motor recovery. The investigators further would like to translate the technologies from lab to home-based training. Thus, the investigators will conduct a randomized, controlled, primarily home-based clinical trial using an ankle robot alone or combined with functional electrical stimulation (FES) to treat sensorimotor and locomotion impairments post-stroke.

Eligibility

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.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
