What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study explores whether a robotic device that amplifies a person's own walking movements can help improve balance in people who have had a stroke. Participants with chronic stroke (more than 6 months ago) will do two treadmill walking sessions—one in a normal environment and one with the movement-amplifying robot. The goal is to see if this novel training helps them control their balance better during walking.

What this could mean

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

Active substance
robotic movement amplification device
What this could lead to
If it works, this could lead to a new gait training method that improves walking balance and quality of life for stroke survivors.
What could go wrong
This is a small, early-stage study with only 30 participants, so results may not apply to everyone. The training is short-term and may not produce lasting improvements.

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 30 people

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

Started

Aug 2024

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

A government agency

The lead sponsor is a US federal agency other than the NIH.

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

Inclusion Criteria: * History of chronic stroke (more than 6 months post-stroke) with weakness on one side * Ability to ambulate over ground for 10 meters with or without a single cane, and/or ankle-foot orthosis * Ability to tolerate 10 minutes of standing Exclusion Criteria: * Presence of cognitive impairment (score of 22/30 on the Montreal Cognitive Assessment scale (MoCA)) * Presence of aphasia (score of 71/100 on the Mississippi Aphasia Screening Test (MAST)) * Excessive spasticity in lower limbs (score of \> 3 on the Modified Ashworth Scale * Severe cardiovascular and pulmonary disease affecting gait and balance * History of recurrent fractures or known orthopedic problems in the lower extremities (i.e. heterotopic ossification) affecting gait and balance * Concomitant central or peripheral neurological injury (i.e. traumatic head injury or peripheral nerve damage in lower limbs) affecting gait and balance * Evidence of cerebellar ataxia * Presence of unhealed decubiti or other skin compromise * Enrollment in concurrent physical therapy or research involving gait or balance training * Use of braces/orthotics crossing the knee joint * Known pregnancy
