简要总结
Few treatments are available for post-stroke rehabilitation. The current study aims to develop a novel, short-term, high-dose repetitive transcranial magnetic stimulation (rTMS) based intervention to improve post-stroke cognitive problems. This study will test the safety as well as changes in cognitive function and brain activation with the administration of an accelerated rTMS protocol in chronic stroke.
详细描述
The goal of this pilot study is to determine whether a repetitive high-dose form of non-invasive brain stimulation is a promising and safe treatment for stroke-related cognitive difficulties. Repetitive transcranial magnetic stimulation (rTMS) is an FDA approved treatment for depression, and is used commonly to treat people for their depression. In studies of rTMS for depression and other disorders, individuals have experienced improved cognitive function. Thus, we are testing here whether cognitive function in individuals with chronic stroke could be improved by rTMS.

研究组 & 干预措施
Dose 1
All participants would receive open-label treatment for approximately eight, 3-minute sessions of intermittent theta burst rTMS on each of three days within a seven-day span. A single session=600 pulses at 120% rMT, iTBS triplets at 50 Hz for 2 s and repeated every 10 s for a total of 190 s to left dlPFC. Total pulses=14,400.
干预措施: Repetitive Transcranial Magnetic Stimulation (rTMS)
结局指标
主要结局
Demonstrate acceptability of an accelerated protocol of rTMS in stroke patients using an acceptability of rTMS questionnaire.
时间窗: Approximately 6 months.
This study will be demonstrating the acceptability of using rapid transcranial magnetic stimulation (rTMS) in stroke patients by using an rTMS acceptability scale. The acceptability scale maximum is 100 and the minimum is 0, a higher score means better outcome.
Incidence of Treatment-Emergent Adverse Events and Side Effects as assessed by iTBS Review of Systems
时间窗: Approximately 6 months.
This study will be demonstrating the safety of using rTMS in stroke patients by assessing adverse events and side effects using the intermittent transcranial brain stimulation (iTBS) Review of Systems questionnaire. The minimum value of the iTBS scale is 0 and the maximum is 75, the higher the score the more severe the side effects meaning a worse outcome.
Assess feasibility, of an accelerated protocol of rTMS in stroke patients looking at retention and using an rTMS a credibility questionnaire pre/post treatment.
时间窗: Approximately 6 months.
This study will be demonstrating the feasibility of using rapid transcranial magnetic stimulation (rTMS) in stroke patients by assessing retention throughout the study and using a credibility scale. The credibility scale maximum is 36 and minimum is 0, a higher ratings means higher credibility score which is a better outcome.
