The Research Team Aims to Elucidate the Impact of ITBS (intermittent Theta Burst Stimulation) on the HPA Axis and Post-stroke Negative Emotions/depression by Conducting Human Experiments That Target Various Brain Regions.
Sponsor: The Second Affiliated Hospital of Kunming Medical University
Summary
The project team will categorize stroke patients into three groups receiving iTBS stimulation targeting distinct brain regions: the cerebellum, the dorsolateral prefrontal cortex (DLPFC), and the primary motor cortex (M1), with 20 patients allocated to each group. Neurofunctional scores, anxiety and depression assessments, and transcranial magnetic stimulation evoked potentials (TEP) will be assessed pre- and post-treatment within each group. The relationship between anxiety and depression scores and brain network characteristics associated with emotions will be examined to investigate the impact of iTBS stimulation on post-stroke negative emotions. Furthermore, plasma and saliva samples will be collected from stroke patients in each group post iTBS intervention. ELISA will quantify ACTH levels in plasma and cortisol levels in both plasma and saliva, with the aim of exploring the effects of iTBS stimulation on the HPA axis across different brain regions.

iTBS
Sixty patients experiencing post-stroke negative emotions were recruited and categorized into groups based on their conditions. The group with post-stroke balance dysfunction underwent intermittent theta burst stimulation (iTBS) of the cerebellum, while the group with post-stroke cognitive dysfunction received iTBS stimulation of the left dorsolateral prefrontal cortex (DLPFC), and the group with post-stroke motor dysfunction underwent iTBS stimulation of the primary motor cortex (M1).The TMS stimulation protocol consisted of 20-minute sessions, five times a week, for a total of ten sessions, utilizing a figure-of-eight coil (model B9076, coil diameter 92 mm, manufactured by Yiruide Company in Wuhan, China, transcranial magnetic therapy device model NS5000). The stimulation intensity was set at 80% of the active motor threshold, with the coil positioned tangentially to the scalp and the handle oriented upwards.
