A Novel Approach for Brain Stimulation in Severe Stroke
In Brief
A Early Phase 1 clinical trial evaluating New Repetitive Magnetic Stimulation (rTMS) Approach and Conventional Repetitive Magnetic Stimulation (rTMS) Approach for Stroke. Completed, enrolled 16 participants across 1 site.
Detailed Summary
The long-term goal of this project is to develop upper limb rehabilitation interventions that can be utilized for stroke survivors, specifically survivors with more severe limitations in use of their affected upper limb. This study will utilize a novel method of non-invasive brain stimulation in conjunction with upper limb training given for 12 visits over a period of 6 weeks. The study will include the following site visits: * Eligibility Screening and Informed Consent Visit * An MRI visit * Two testing visits in which motor function of the upper limb and neurophysiology will be measured * 12 intervention visits during which patients will receive upper limb training in conjunction with non-invasive brain stimulation * Repeat testing of motor function of the upper limb and neurophysiology * Repeat MRI testing * A follow-up visit completed 3 months after the completion of interventions

Timeline
Interventions
Participants in this arm will receive rTMS-based facilitation of the contralesional dorsal premotor cortex (cPMd) located in the non-stroke hemisphere before start of each session. High-frequency rTMS (5-Hz) will be delivered using 42 10-sec trains of 50 pulses each (total 2100 pulses) for a period of 24 minutes. Immediately after the completion of rTMS, participants will undergo upper limb training for a total of one hour. Participants will receive these interventions 2 days a week for 6 weeks, i.e., for a total of 12 sessions.
Participants in this arm will receive rTMS-based facilitation of the ipsilesional primary motor cortex (iM1) before the start of each session. iM1 will be stimulated with high-frequency rTMS (5-Hz) using 42 10-sec trains of 50 pulses each (total 2100 pulses) for a period of 24 minutes. Immediately after the completion of rTMS, participants will undergo upper limb training for a total of one hour. Participants will receive these interventions 2 days a week for 6 weeks, i.e., for a total of 12 sessions.
