Awards & highlights

Summary

This trial will test whether specific time windows for combined brain and nerve stimulation are more effective than random time windows in improving post-stroke hand function.

Who is the study for?
This trial is for individuals who have had a stroke at least 6 months ago and now struggle with hand function due to upper extremity hemiparesis. They must be mentally fit (with a Mini Mental State Exam score over 24), willing to participate, able to consent, and have some movement in their affected arm but not full recovery (Fugl-Meyer score under 66).Check my eligibility
What is being tested?
The study tests whether delivering paired corticomotoneuronal stimulation (PCMS) during specific brain states improves hand function after stroke compared to random timing of PCMS. It aims to strengthen the neural pathways that control the hand by using combined brain and nerve stimulation.See study design
What are the potential side effects?
While side effects are not explicitly listed, potential risks may include discomfort or mild pain from nerve stimulation, headache or scalp discomfort from TMS, and possible temporary worsening of motor symptoms.
