Observation on the Therapeutic Effect of Low-Intensity Transcranial Ultrasound Stimulation Combined With Upper Limb Virtual Reality Training on Post-Stroke Depression

"LITUS is conducted using the UE880C model from RuAo Medical Technology Co., Ltd. (Beijing). The parameters are set as follows:Frequency: 800(1+10%) kHz,Pulse repetition period: 25 ms,Duty cycle: 50%,Output power: 1.2 W,Maximum output power duration: 0.6 W,Effective sound intensity: 0.4 W/cm².During treatment, the patient is placed in a quiet room and asked to relax in a seated position. Three ultrasound probes are coated with a coupling agent and positioned on the patient's forehead.The total treatment duration is 20 minutes.~The upper limb rehabilitation virtual training is used by the EM-BURT02-01 model from Eston.The affected limb is fixed to the robotic arm. Each treatment session consists of two virtual games (such as Airplane Battle, Mosquito Smasher, and other motion-based games).Each game lasts for 10 minutes, totaling 20 minutes of treatment. Treatment is administered 5 times a week."

In the sham group, the machine only operates for 30 seconds, then stopping. Due to the physical characteristics of ultrasound, this stimulation cannot be perceived.Treatment is administered 5 times a week.
