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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 whether adding functional electrical stimulation (FES) to arm cycling exercises improves aerobic fitness and arm function in people who had a stroke within the last 6 months. 24 participants will be split into two groups: one doing arm cycling alone, the other doing arm cycling with FES, both alongside standard rehab. The goal is to see if the electrical stimulation provides extra benefits for recovery.

What this could mean

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

Active substance
Functional electrical stimulation (FES) combined with upper extremity ergometer training
What this could lead to
If successful, this could point toward a more effective rehabilitation method to improve arm function and fitness after a stroke.
What could go wrong
This is a small, early-stage trial with only 24 participants, so results may not apply to all stroke patients. The intervention is short-term (10 sessions over 4 weeks), and benefits may be modest or not sustained.

Study facts

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 24 people

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

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.

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

Inclusion Criteria: * Inclusion Criteria: * Age between 18 and 85 years * Diagnosis of subacute stroke (≤6 months after stroke onset) * Ischemic or hemorrhagic stroke confirmed by imaging * Unilateral hemiplegia affecting the upper extremity * Brunnstrom upper extremity motor recovery stage between 1 and 5 * Modified Ashworth Scale score \<3 in the affected upper extremity * Ability to follow simple verbal commands and cooperate with assessments * Medically stable and able to participate in an exercise-based rehabilitation program * Voluntary agreement to participate in the study and provision of written informed consent Exclusion Criteria: * Severe cognitive impairment or communication disorder preventing cooperation * Severe cardiopulmonary disease or other medical conditions contraindicating exercise testing or training * Uncontrolled hypertension or cardiac arrhythmia * Severe musculoskeletal disorders of the upper extremity limiting participation in ergometer training * Presence of implanted electronic devices (e.g., pacemaker) contraindicating functional electrical stimulation * History of epilepsy or uncontrolled seizures * Severe spasticity (Modified Ashworth Scale ≥3) * Participation in another interventional study during the study period
