Efficacy of Repeated Transcranial Magnetic Stimulation Based on Near-infrared Imaging in Patients With Post-stroke Depression

To evaluate the efficacy and safety of low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) for the right dorsolateral prefrontal cortex (DLPFC) in patients with post-stroke depression (PSD), and explore the possible neural mechanism of rTMS with Functional near-infrared spectroscopy (fNIRS). Patients were randomly assigned to the rTMS and control groups. the treatment effect was assessed by the Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), National Institutes of Health Stroke Scale (NIHSS), and Barthel Index (BI). Meanwhile, fNIRS was used to detect the changes of blood oxygen concentration in the frontal cortex. After treatment, the score of the HAMD scale in the rTMS group decreased more significantly than in the control group (P\<0.05). The value of CH17 oxyhemoglobin (HBO) and the value of CH6 deoxyhemoglobin (HBR) were decreased after rTMS. The HbR of CH6 and CH8 decreased significantly, the HbR of CH12 and CH15 increased significantly (P\<0.05). The HAMA, NIHSS and Barthel scores improved more significantly in the rTMS group.
