A pulsed magnetic stimulation device (M‐100 Ultimate; Shenzhen Yingchi Technology Co. Ltd., Shenzhen, China) was used for rTMS therapy in ID patients. Stimulation was performed with a figure‐of‐eight stimulation coil at the left DLPFC (site: Cz to the left 3–5 cm, forward 5 cm). The following stimulation parameters were used (Zhang et al., 2018): stimulus frequency, 1 Hz; stimulus intensity, 80% of the motion threshold (motion threshold defined as the lowest stimulation power that can produce five finger movements out of 10 stimuli), stimulation number 10 pulses/string, string interval 2 s, a total of 150 strings, total stimulation pulses 1500, total stimulation time 30 min, one session per day, and 5 days per week for a 4‐week treatment course (2 days off each weekend). Sham rTMS was also performed, as the coil was turned away from the skull at 90°. No side effects were reported during or after brain stimulation.
