What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This early study tests a robotic leg brace with smart software that senses how a person walks and adjusts its help in real time. Researchers want to see if this adaptive system improves walking speed and balance in stroke survivors compared to a standard brace. About 20 people, including healthy adults and chronic stroke survivors, will walk on treadmills and stairs while wearing the device.

What this could mean

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

Active substance
AI-driven control software for a lower-limb powered orthosis (exoskeleton)
What this could lead to
If it works, this could lead to a smarter exoskeleton that helps stroke survivors walk faster and more naturally, improving daily independence.
What could go wrong
This is a very early pilot study with only 20 participants, so results may not apply to all stroke survivors. The technology is still experimental and may not provide lasting benefits.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 20 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Oct 2026

An estimate. Start dates often move.

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 80 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Cohort 1: Able-Bodied Participants (Initial Validation) * Healthy young adults. * No history of neurological, orthopedic, or cardiovascular impairments affecting gait or balance. * Able to walk independently without assistive devices. Cohort 2: Stroke Survivors (Clinical Efficacy Pilot) * Individuals with a documented history of chronic stroke. * Persistent unilateral lower-limb motor impairment resulting in a pathological gait pattern (heterogeneous gait deficits). * Stable medical condition allowing for participation in intensive physical rehabilitation tasks. * Able to provide informed consent. Exclusion Criteria: * Severe cognitive or communication impairments that prevent the participant from following safety instructions or reporting discomfort. * Co-existing neurological conditions (other than stroke) that independently impair locomotion (e.g., Parkinson's disease, Multiple Sclerosis). * Severe lower-limb joint contractures or orthopedic conditions that mechanically restrict the safe range of motion of the robotic orthosis. * Skin breakdowns, open wounds, or severe unhealed lesions at the contact points where the powered orthosis interfaces with the lower limbs. * Any medical contraindication to intensive walking exercise or treadmill training (e.g., unstable angina, severe unmanaged cardiovascular disease).
