Acupuncture stimulation procedures. A) Anatomical location of the acupoints LI3 and LI4 on the right hand; used for genuine and sham acupuncture administration. B) Schematic illustration of the timing during treatment blocks. In total, electroacupuncture (EA) treatment was applied for approximately 25 minutes at a frequency of 2 Hz. Treatment was given in blocks of 6.5-minute current ON and four 1.5-minute current OFF blocks. For sham EA, the sham needle was attached to a de-activated EA device, and no current was applied during the 25 minute treatment.
