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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looked at how older adults (65+) adapt their walking when one leg moves faster than the other on a split-belt treadmill. Researchers measured brain activity and balance to understand the link between automatic walking and mobility. The goal was to learn more about how aging affects walking adaptability, not to test a treatment.

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

44 people

The number who actually took part.

Started

Nov 2021

Finished

May 2025

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

19 years and older

Sex

Anyone

Healthy volunteers

Accepted

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

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

Inclusion Criteria: * 19 years old or older. * Body Mass Index of 35 or less. Muscle activities will be recorded for distinct muscles in the legs and fatty tissue could interfere with these measurements. * Able to walk without a hand held device * Able to walk for 5 minutes at their self-paced speed Exclusion Criteria: * Any past or present history of neurological disorders, heart or respiratory disease, brain injury, seizures, spinal cord surgery, or strokes. * Pregnancy. * Unable to follow two part commands; * Uncorrected vision or severe visual impairment with visual acuity \< 20/70 with best correction; * Cognitive impairments defined as modified mini-mental score \<84; * orthopedic or pain conditions (lower extremity pain, back pain, calf pain); * refuse to walk on a treadmill; * hospitalized 6 months prior to the study for acute illness or surgery, other than minor surgical procedures; * lower extremity orthopedic surgery within 1 year; * uncontrolled hypertension (\> 190/110 mmHg); * diagnosed dementia; * dyspnea at rest or during daily leaving activities; * use supplemental oxygen, resting heart rate\> 100 or \<40 beats per minute; * fixed or fused hip, knee, or ankle joints; * progressive movement disorder such as Multiple Sclerosis (MS), Amyotrophic Lateral Sclerosis (ALS), or Parkinson's disease
