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

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 Results may not be published yet.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

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.

Summary

This study tests different power levels and timing of low-intensity focused ultrasound (LIFUS) to see which best improves arm movement and motor learning in stroke survivors. 24 adults who had a stroke at least 6 months ago and have arm weakness will participate. The goal is to find the optimal LIFUS settings for future therapies.

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

Inclusion Criteria: * age \>=21 years old of any gender or race * First-ever ischemic or hemorrhagic stroke (neuroimaging verified) at least 6 months from the stroke onset of symptoms * Unilateral arm weakness measured by the Fugl-Meyer Upper-Extremity Scale ≤ 62/64 * Inducible resting motor threshold and testing motor threshold recorded from an affected upper extremity muscle Exclusion Criteria: * Bilateral strokes (infarcts and/or hematoma) * Other co-existent neuromuscular disorders affecting upper extremity motor impairment * History of medically uncontrolled depression or other neuropsychiatric disorders despite medications either before or after a stroke that may affect the subject's ability to participate in the study * History of confirmed dementia or taking dementia drugs * Uncontrolled hypertension despite medical treatment(s) at the time of enrollment, defined as SBP≥185 mmHg or DBP≥110 mmHg (patient can be treated, reassessed and enrolled later) * Presence of any MRI/TMS/LIFUS risk factors * Concurrent enrollment in another interventional stroke recovery study * Concerns that the subject cannot comply with study procedures and visits * Pregnant
