Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Electro-acupuncture group
Patients in EA group receive acupuncture at Shuigou (also known as Renzhong, GV26) and Yintang (updated number GV24+, previous number GV29). Paired electrodes from the EA apparatus are clipped to the needle handles at Shuigou and Yintang. The electroacupuncture stimulation lasts for 30 minutes with a wave of rarefaction and condensation (10 Hz / 50 Hz) and a current intensity of the maximum withstand current within 7mA. All patients receive EA at 9 am for 30 minutes once a day for consecutive 14 days.
Electroacupuncture
Electro-acupuncture at Shuigou and Yintang.
Sham electro-acupuncture group
Patients in sham-EA group receive sham-EA at sham-Shuigou and sham-Yintang.Acupuncture needles are inserted into the adhesive pads but do not pierce the skin. Paired electrodes from the EA apparatus via sham connecting cords are clipped to the needle handles at sham-Shuigou and sham-Yintang. The sham connecting cords are similar in appearance to the normal ones, but the inner wires in sham connecting cords are cut off and cannot conduct electricity. All patients receive sham-EA at 9 am for 30 minutes once a day for consecutive 14 days.
