Leg muscle tests could pave way for smarter exoskeletons

NCT ID NCT07465328

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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 measures how much force leg muscles can produce and how they use oxygen in people with stroke or sarcopenia (age-related muscle loss). Researchers will test hip, knee, and ankle strength at different angles and speeds. The goal is to gather data that could help design better leg exoskeletons for these patients. The study involves 42 participants, including healthy volunteers for comparison.

What this could mean

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

What this could lead to
If successful, this study could help design better leg exoskeletons tailored to the needs of stroke and sarcopenia patients.
What could go wrong
This is a small, observational study (42 people) that measures muscle function, not a treatment trial. The findings may not apply to all patients or lead directly to a device.

This is an AI summary of the original study and may miss details. Read our disclaimer.

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 42 people

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

Started

Feb 2025

Expected to finish

Feb 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 years and older

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.

Post stroke patients: * Must be 18+ years old * Must be three months or more after stroke diagnosis * Have difficulties with gait (FAC level 3-4) Sarcopenia patients: * Must be 65+ years old * Not be able to perform five chair sit to stands within 15 seconds * Grip strength of less than 27 kg for men and less than 16 kg for females * Have difficulties with gait (SPPB ≤ 8) Healthy participants: • No physical injuries that limits the torque production in lower-limb joints
