Trial Outcomes & Findings for Effect and Safety of Electroacupuncture for Symptoms of Menopausal Transition (NCT NCT01849172)

NCT ID: NCT01849172

Last Updated: 2019-04-02

Results Overview

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.

One session will be given every two days, 3 sessions per week (24 sessions in all) and each session lasts for 30 minutes. acupuncture: 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, up 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.

Timeframe: at baseline and week 8

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).

Electroacupuncture
n=180 Participants
Acupoints of RN4, Bilateral EX-CA1, ST25 and SP 6 were used.For acupoints in the abdomen, the needles will be inserted vertically and then slowly and vertically penetrate through the layer of fatty tissue, up into the muscles of the abdominal wall. The needle will be inserted vertically at SP6 to a depth of 1 cun. Paired alligator clips of the EA apparatus will be attached transversely to the needle holders of the bilateral EX-CA1 and ST25. EA stimulation will last for 30 minutes with a dilatational wave of 10/50Hz and current intensity of 0.1 to 1mA. The current intensity will be increased until the skin around the acupoints shivers. The manipulation on RN4 and SP6 mentioned above should be performed every 10 minutes, three times in 30 minutes.Patients will be treated with EA 3 sessions a week on alternate days for 8 successive weeks, 24 sessions for each patient in total.
Sham Electroacupuncture
n=180 Participants
Non-points proximate to RN4 , EX-CA1,ST25 and SP6 were used. After sterilizing the skin, placebo needles of size 0.30×25 mm will be needled into adhesive pads without skin penetration or needle manipulation. The needle will be manipulated slightly with an even lifting, thrusting, and twisting method repeated three times for each point but no deqi. Paired alligator clips of the specially made EA apparatus (power output lines, which connect the alligator clips and the EA apparatus, will be cut inside with an appearance as usual) will be attached transversely to the needle holders of the bilateral sham-ST25 and sham-EX-CA1. The EA apparatus will be turned on with a working power indicator and the same sound as the EA group. The parameters of sham EA apparatus and the treatment course will be the same as in the EA group.

The 24-h hot flash score was daily hot flash episodes multiplied by the corresponding severities. The change from baseline in mean 24-h HF score at weeks 4, 8, 20 and 32 equals the mean 24-h HF score at weeks 4 , 8, 20 and 32 minus the mean 24-h HF score at baseline, respectively. Hot flashes score consisted the number and the degree of hot flashes. The hot flashes score is the sum of the scores of all the hot flashes occurring in a whole day, with a higher score indicating worse symptoms. A 3-point rating scale allows the women to describe the perceived severity of hot flash. 1 point = mild hot flash, 2 point = moderate hot flash, 3 point = severe hot flash.

It composed of 29 items and was divided into four domains: vasomotor (items 1-3), psychosocial (items 4-10), physical (items 11-26), and sexual (items 27-29). Each of the item scores ranges from 0 to 6. The total score will be calculated as the all items ranging from 0 to 174, with lower scores indicating a better quality of life.

The change from baseline in the vasomotor domain of Menopause-Specific Quality of Life Questionnaire (MENQOL) at weeks 4, 8, 20 and 32 equals the vasomotor domain of MENQOL at weeks 4, 8, 20 and 32 minus the vasomotor domain of MENQOL at baseline, respectively. The vasomotor domain contains 3 items (items 1-3). Each of the item scores ranges from 0 to 6. The vasomotor domain score will be calculated as the all vasomotor items ranging from 0 to 18, with lower scores indicating a better quality of life.

Acupoints of RN4, Bilateral EX-CA1, ST25 and SP 6 were used.For acupoints in the abdomen, the needles will be inserted vertically and then slowly and vertically penetrate through the layer of fatty tissue, up into the muscles of the abdominal wall. The needle will be inserted vertically at SP6 to a depth of 1 cun. Paired alligator clips of the EA apparatus will be attached transversely to the needle holders of the bilateral EX-CA1 and ST25. EA stimulation will last for 30 minutes with a dilatational wave of 10/50Hz and current intensity of 0.1 to 1mA. The current intensity will be increased until the skin around the acupoints shivers. The manipulation on RN4 and SP6 mentioned above should be performed every 10 minutes, three times in 30 minutes.Patients will be treated with EA 3 sessions a week on alternate days for 8 successive weeks, 24 sessions for each patient in total.

Non-points proximate to RN4 , EX-CA1,ST25 and SP6 were used. After sterilizing the skin, placebo needles of size 0.30×25 mm will be needled into adhesive pads without skin penetration or needle manipulation. The needle will be manipulated slightly with an even lifting, thrusting, and twisting method repeated three times for each point but no deqi. Paired alligator clips of the specially made EA apparatus (power output lines, which connect the alligator clips and the EA apparatus, will be cut inside with an appearance as usual) will be attached transversely to the needle holders of the bilateral sham-ST25 and sham-EX-CA1.
