干预措施:

Interventions:

组别:

taVNS组

样本量:

50

Group:

The taVNS group

Sample size:

干预措施:

将刺激电极置于左侧耳甲部位,每日2次,每次干预持续30分钟,持续4周。刺激参数为200 μs的单相、方波,4/20Hz频率交替(4Hz持续3s,20Hz持续7s),调整至个体在不引起疼痛的情况下可耐受的最强感觉,通常为4-6 mA

干预措施代码:

Intervention:

Place the stimulating electrodes on the left auricle area. Perform the intervention twice a day, each session lasting 30 minutes, for a total of 4 weeks. The stimulation parameters are a 200 μs single-phase, square wave at a frequency of 4/20 Hz (4 Hz for 3 seconds, 20 Hz for 7 seconds), adjusted to the strongest sensation that the individual can tolerate without experiencing pain, typically at 4-6 mA.
