The motor threshold of 100% intensity, a TBS stimulus train for 2 seconds, including 10 times of 3 intrapascicular stimulation at 50 Hz and interapascicular stimulation at 5HZ, intervals of 10s, 60 repetitions, that is, a total of 1800 pulses per treatment, 6 treatments per day, 50 min apart, a total of 10800 pulses/day, continuous stimulation for 5 days.
The motor threshold of 100% intensity, a TBS stimulus train stimulation for 2 seconds, including 10 times of 3 intrapascicular stimulation at 50 Hz and interapascicular stimulation at 5HZ, intervals of 10s, 60 repetitions, that is, a total of 1800 pulses per treatment, 10 treatments per day, intervals of 50 min, a total of 18000 pulses/day, continuous stimulation for 5 days.
The appearance of the sham stimulation coil was consistent with that of the real stimulation coil, which could simulate the touch and sound of the scalp caused by the real stimulation. The treatment frequency, location, intensity and time of the sham stimulation group were the same as those of the real stimulation group.

The Hamilton Depression Scale (24-items), is a 24 item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. It's considered the gold standard for rating depression severity and used frequently in clinical trials. Higher HAM-D24 score indicates more severe depression, and each item yields a score of 0 to 4. Remission is defined as HAM-D24 ≤8. A reduction of 50% or more in total score from Baseline indicates clinical response.

Hamilton Anxiety Scale is a 17 item diagnostic questionnaire used to measure the severity of anxiety episodes in patients. Each item on the scale is rated on a 5-point scale from 0 (not present) to 4 (severe), with the total score ranging from 0 to 68. The HAMA-17 is often used in clinical and research settings to assess the severity of anxiety symptoms and to evaluate the effectiveness of treatments for anxiety. It is a more comprehensive version of the HAMA that includes additional items to capture a broader range of anxiety symptoms.
Time frame: Baseline to end of stimulation period, an average of 5 days
Beck Scale of Suicidal Ideation is a 21-item self-report instrument that detects and measures the intensity of a patient's specific attitudes, behaviors, and suicide plans during the past week. The BSI score ranges from 0 to 63, with higher scores indicating worse outcomes and lower scores indicating better outcomes.

Scanning functional magnetic resonance. Functional magnetic resonance imaging (fMRI) is a neuroimaging technique that is used to measure changes in brain activity by detecting changes in blood flow. In the context of major depression, fMRI has been used to study changes in brain function that may be associated with the condition. Research using fMRI in major depression has shown that there are alterations in the activity of certain brain regions in people with the condition.
Time frame: Baseline to end of stimulation period, an average of 5 days
Electroencephalogram is collected from 64 electrodes. EEG can be used to identify patterns of brain activity that are associated with the condition and to inform treatment decisions. EEG can be a useful tool for identifying patterns of brain activity that are associated with TRD and for guiding treatment decisions. Neurofeedback and TMS are two approaches that have shown promise in the treatment of TRD. several parameters are analyzed to identify patterns of brain activity that may be associated with the condition. These parameters include:Alpha power, Beta power, Theta power, Delta power,etc.
