Abstract:

objective:To study whether post-stroke depression can be improved through low-intensity transcranial ultrasound stimulation combined with upper limb virtual reality training, explore its possible mechanisms, and provide new rehabilitation strategies for further treatment of post-stroke depression patients.

Methods:30 patients with PSD were selected as the subjects, and randomly divided into sham control group and combination treatment group according to computer randomization. Each group was 15 cases. The combined treatment group was subjected to LITUS, virtual reality upper limb training, routine medication and rehabilitation treatment. The control group only conducted virtual upper limb training, routine medication and rehabilitation treatment, and TUS was a false stimulation treatment.
