Overview
To clarify the clinical efficacy of high-frequency rTMS on patients with post-stroke cognitive impairment, fNIRS and EEG techniques were used to observe the changes in brain functional activities of patients with post-stroke cognitive impairment after rTMS treatment, and to clarify the neuroregulatory effect of rTMS on patients with post-stroke cognitive impairment.
Description
The experimental group will receive rTMS stimulation therapy, which involves applying high-frequency 10Hz rTMS to the patient's head for 20 minutes, once a day, for a total of 20 sessions. The control group will undergo rTMS sham stimulation therapy, using a sham stimulation coil to apply the same parameters and method of stimulation to the head. Although the sham stimulation coil has no difference in appearance and sound from the real stimulation coil, it cannot generate a real magnetic field to stimulate the brain. You need to be evaluated before the treatment begins, after 10 sessions, and 20 sessions of the treatment. The evaluation content includes: Researchers will use relevant clinical evaluation scales to conduct functional evaluations on you, and perform near-infrared and electroencephalogram brain imaging measurements.
