Acupoints including bilateral BL23, BL32, BL33, BL35 and SP6 are inserted with acupuncture needles(size 0.30 × 40 mm and 0.30 × 75 mm or 0.40 × 100 mm,Hwato Brand). Bilateral BL32 and BL33 are needled to a depth of 70-95 mm with an angle of 60°-75° inward and downward, into the second and third sacral foramen. Bilateral BL35 are needled to a depth of 60-70 mm in a slightly superolateral direction. Bilateral BL23 and SP6 are vertically needled to a depth of 25-30 mm. After deqi is evoked, electric stimulators with a 5Hz continuous wave (5-10 mA intensity) are separately connected to bilateral BL32, BL33,BL35 and SP6.
