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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a wearable device called a myoelectric-computer interface (MCI) that helps stroke survivors improve arm movement by reducing abnormal muscle co-activation. The device uses muscle signals to guide a video game, providing feedback to retrain coordination. Researchers will enroll 96 people with acute or chronic stroke to test if home use of the MCI is feasible and effective.

What this could mean

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

Active substance
myoelectric-computer interface (MCI) device
What this could lead to
If successful, this could provide a home-based therapy to improve arm function in stroke survivors without medication.
What could go wrong
This is an early feasibility study with only 96 participants, so results may not apply to all stroke survivors. The device may not work better than a sham control.

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 96 people

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

Started

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

Inclusion Criteria: Chronic stroke participants * Hemiparesis from first ever stroke at least 6 months prior to screening * Severe motor impairment (FMA of 7-30) * At least some voluntary shoulder and elbow muscle activation. Acute stroke participants * Hemiparesis from first ever stroke within the past 21 days * Severe motor impairment (FMA of 3-20), or total Manual Motor Score of 1-8 combined in Shoulder Abduction and Finger Extensors Exclusion Criteria: * Cognitive impairment with at least moderately impaired attention, or unable to follow instructions of the MCI task * Visual impairment (such as hemianopia) preventing full view of the screen * Anesthesia or neglect in the affected arm, or visual hemineglect (score of 2 on the NIH Stroke Scale Extinction and Inattention subtest). * Participation in another study on the affected arm within 6 weeks of enrollment or any pharmacological study * Inability to understand or follow commands in English due to aphasia or other reason * Diffuse or multifocal infarcts * Substantial arm pain preventing participation for 90 minutes a day * New spasticity treatment (pharmacological or Botox)
