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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested whether robotic training that adjusts errors based on each person's abilities can improve motor learning in healthy adults and people with neurological conditions like stroke. Over 250 participants performed arm tasks with robotic devices while researchers measured movement, force, and brain activity. The goal was to understand how to design better rehabilitation strategies, not to provide a direct treatment.

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 research could point toward more effective, personalized robotic training programs for people recovering from stroke or other neurological conditions.
What could go wrong
This is a completed early-stage study focused on measuring learning and brain activity, not a treatment trial. The findings may not directly translate into a therapy or benefit all patients.

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

259 people

The number who actually took part.

Started

Jan 2019

Finished

Oct 2024

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.

Inclusion Criteria: * Aged ≥18 years * Informed Consent as documented by signature ("Informed Consent" form) * Bodyweight \<120 kg * Ability to communicate effectively with the examiner so that the validity of the patient's data could not be compromised Exclusion Criteria: * Excessive spasticity of the affected arm (Ashworth Scale ≥3) * Serious medical or psychiatric disorder * Orthopaedic, rheumatological, or other disease restricting movements of the paretic arm * Shoulder subluxation * Skin ulcerations at the paretic arm * Cyber-sickness (i.e., nausea when looking at a screen or playing computer games) * Serious cognitive defects or aphasia preventing effective use of the robotic devices * Severe visual and auditory impairments
