Effect and Safety of Electroacupuncture for Symptoms of Menopausal Transition

Effect and Safety of Electroacupuncture for Symptoms of Menopausal Transition -a Multicenter Randomized Controlled Trial

The primary object is to evaluate the efficacy and safety of electroacupuncture for symptoms of women during menopausal transition .

Study Overview

• Status: Completed
• Conditions: Menopausal Syndrome
• Intervention / Treatment: Other: electroacupuncture; Other: sham electroacupuncture

Detailed Description

Menopause transition is called perimenopause in the past time. 40-80% women aged 40 to 65 have symptoms during this period. Hormone therapy is the recommended therapy for menopause and there is not enough evidence in favor of alternative medicine's effect.

Our pilot trial showed that electroacupuncture had better effect for menopause transition symptoms than sham electroacupuncture. We are going to conduct a phase Ⅱ clinical trial to further evaluate the safety and effect of electroacupuncture for menopause transition symptoms.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: electroacupuncture; Electroacupuncture at RN4, EX-CA1，ST25, SP6 (double sides). One session will be given every two days, 3 sessions per week (24 sessions in all) and each session lasts for 30 minutes.	Other: electroacupuncture; Stick adhesive tapes to all points. For ST25, EX-CA1 and RN4, insert the needle vertically through the pads and the skin, and then slowly and vertically penetrate through the layer of fatty tissue, into the muscles of the abdominal wall .For RN4, manipulate the needle with an even lifting, thrusting and twisting method slightly for 3 times. Insert the needle vertically at SP6 to a depth of 1 cm. Manipulate the needle with an even lifting, thrusting and twisting method slightly for 3 times to reach de-qi. Put the electric stimulator on the pair of EX-CA1 and ST25 points with a dilatational wave, 10/50 Hz, 0.5-1.0mA. To turn on the current intensity till the abdomen shivers. The same manipulation methods for RN4 and SP6 will be given every 10 minutes (3 times in all).
SHAM_COMPARATOR: sham electroacupuncture; Sham electroacupuncture at non-points proximate to RN4 (P1), EX-CA1(P2)，ST25 (P3) and SP6 (P4) (double sides).Specially constructed EA apparatus were used with no skin penetration, electricity output, or de qi requirement for needle manipulation One session will be given every two days, 3 sessions per week (24 sessions in all) and each session lasts for 30 minutes.	Other: sham electroacupuncture; Non-points proximate to RN4 (P1), EX-CA1(P2)，ST25 (P3) and SP6 (P4) (double sides) are used.P1 and P3 are at the sites 1 cm (outward in horizontal direction) proximate to RN4 and ST25 respectively. P2 is 2 cm (outward in horizontal direction) proximate to EX-CA1. P4 is at the middle site of the spleen meridian and the kidney meridian (backward in horizontal direction proximate to SP6). Stick adhesive tapes to all points. Blunt needles will be used to be inserted to but not piercing the skin. Even lifting, thrusting and twisting manipulation methods will be given for each non-point for 3 times. Put the sham electric stimulator on the pair of P2 and P3 with the same parameters as the acupuncture group. But there is no current intensity actually.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Menopause Rating Scale Total Score	The change in menopause rating scale (MRS) total score compared with baseline at week 8 equals MRS total score at week 8 minus MRS total score at baseline. MRS is a self-report questionnaire for evaluating the severity of menopausal symptoms in women, which contains 11 items. Each of the 11 symptoms contained a scoring scale from "0" (no complaints) to "4" (very severe symptoms). The total score will be calculated as the all items ranging from 0 to 44, with higher scores indicating worse symptoms. The MRS including 3 dimensions: psychological, somatic-vegetative, and urogenital.	at baseline and week 8
