Human-Machine System for the H2 Lower Limb Exoskeleton
(H2-NeuroExo)
What this study is about
This research study will investigate the use of smart lower limb robotic exoskeleton (developed by the CSIC, Spain) in rehabilitation after stroke. It will compare robotic-assisted rehabilitation with supervised motor practice.
View original scientific description
This research study will investigate the use of smart lower limb robotic exoskeleton (developed by the CSIC, Spain) in rehabilitation after stroke. It will compare robotic-assisted rehabilitation with supervised motor practice. Additionally, it will also examine the use of noninvasive scalp electroencephalography (EEG) to learn specific brain wave patterns associated with learning to walk on the powered lower limb exoskeleton. The findings will be used to understand human-robot interaction and to design smart orthotic devices that can be controlled by thought activity and assist those that have lost all or part of their walking abilities.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Sub-acute or chronic stroke i.e., interval of at least 3 months or interval of at least 6 months from stroke to time of enrollment, respectively;
- Cognitive ability to assimilate and participate actively in the treatment protocol (Mini Mental State Examination score \> 24 points, out of a total 30 indicating normal cognitive ability);
- Modified Rankin scale scores 2-4 (Mild-Moderate functional disability post-stroke);
- Modified Ashworth Scale of Spasticity score \<= 2 (ranges from 0-4 with 4 reflecting maximum spasticity);
- Have no skin integrity issues;
- Sufficient passive range of motion at the hip (at least 90 deg flexion, 15-20 deg extension), knee (90 deg flexion, complete extension) and ankle (15 deg dorsiflexion, 15 deg plantarflexion);
- Have no contraindications to standing or walking; able to stand with assistive device for at least 5 minutes, and able to walk with assistive device for 10 m.
Exclusion criteria
- Severe cognitive and/or visual deficit;
- Hemineglect (determined based on medical record or initial clinical assessment);
- Severe sensory deficit;
- Joint contractures of any extremity that limits normal range of motion during ambulation with assistive devices;
- Skin lesions that may hinder or prevent the application of exoskeleton;
- Uncontrolled angina;
- Severe chronic obstructive pulmonary disease;
- Other medical contraindications; any medical co-morbidities that would prevent standard rehabilitation. Inclusion criteria for healthy, able-bodied participants:
- Able to understand and sign the consent form
- Age 18-75 years Exclusion criteria for healthy, able-bodied participants: \- History of neurological, neuromuscular or physical disability.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
