Screening 3 weeks
Treatment Varies
Follow Up at any point during or immediately following intervention on day of lifus application

LIFU Trial Summary

This trial is testing different intensities and frequencies of ultrasound to find a safe and tolerable option for stroke patients.

Who is the study for?
This trial is for adults over 21 who have had a stroke confirmed by CT or MRI at least 2 months ago, with mainly one-sided motor issues and can still induce muscle responses in the affected hand. It's not for those with other neurological disorders affecting arm function, severe pre-stroke dementia, inability to practice motor skills, or risks from MRI/TMS/ultrasound like metal implants or pregnancy.Check my eligibility
What is being tested?
The study aims to determine the safest and most tolerable settings for Low Intensity Focused Ultrasound (LIFU) therapy in stroke patients. Researchers will adjust the intensity and frequency of LIFU to find optimal parameters that could help improve cortical modulation after a stroke.See study design
What are the potential side effects?
While specific side effects are not listed, LIFU may potentially cause discomfort at the stimulation site, headache, or skin irritation. Since it's non-invasive and focuses on brain modulation post-stroke, serious side effects are unlikely but will be monitored.
