Acupuncture Therapy, Hot Flashes, Perimenopausal Disorder, Postmenopausal Symptoms
Conditions
Brief summary
The investigators plan to conduct the randomized controlled trial to evaluate the effectiveness of electro-press needle (EPN), a novel acupuncture needle combining shallow and gentle insertion with transdermal electrical stimulation, on menopause-associated hot flash in comparison with waiting-list group among women during menopausal transition and postmenopausal periods.
Detailed description
As the most common type of menopause-associated symptoms, hot flashes affect up to 85% of women aging between 40 and 65 years . In China, women suffer from hot flushes as long as 4 to 5 years on average, some of whom may bear the symptoms for 12 years.Hormone replacement therapy (HRT) is generally recommended to relieve menopause-associated hot flashes.However, long-term usage of HRT may increase the incidence of endometrial, breast and ovarian cancer, thrombosis and strokes.Results of previous studies indicated that acupuncture might help to relieve the symptoms.There is insufficient evidence supporting its effectiveness for relieving the hot flash symptom.
Interventions
DEVICEElectro Press needle
Body acupoints will be stimulated by the press needles 0.25mm in diameter and 2mm in length and ear acupoints will be stimulated by the press needles 0.25mm in diameter and 0.9mm in length (all from ZhenXing Brand, Hangzhou Yuanli Medical Appliance Factory, China). After sterilization of the local skin, the needle will be pressed to the acupoints and the tape will be sticked to the skin. Then, the electric device (φ44×15.8mm Type ZXHPAMDZB-02C) together with the electrode patch will be sticked to the surface of skin (on top of the sticky tapes of the press needle) in the area of CV4 and bilateral EX-CA1, and bilateral SP6 respectively. The electric device will be switch to the mode of dense intermittent wave, and the current intensity will be increased gradually till the muscles around jumps slightly.All the needles on the body acupoints will be removed after each session, while those on the auricular acupoints can be kept for as long as 6 hours (removed before going to bed).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| the proportion of patients with a reduction of 50% or more on the mean 24-hour HF score from baseline | week 6 | The mean 24-hour HF score = (1 × number of mild HF + 2 × number of moderate HF + 3 × number of severe HF + 4 × number of very severe HF)/Number of days reported. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The proportion of patients with at least a 50% reduction in the mean 24-hour HF severity from baseline | week 3,6,18,30 | The mean 24-hour HF severity = (1 × number of mild HF + 2 × number of moderate HF + 3 × number of severe HF + 4 × number of very severe HF)/ Number of HF reported. |
| The changes in the mean 24-h HF score from baseline | week 3,6,18,30 | The mean 24-hour HF score = (1 × number of mild HF + 2 × number of moderate HF + 3 × number of severe HF + 4 × number of very severe HF)/Number of days reported. |
| The change of Menopause rating scale (MRS) score from baseline | week6, 18 and 30 | MRS is a common menopause specific subscale, including 11 items from psychological, somatic to urogenital, with 5 as minimal clinically important differences(MCID). |
| TThe change of Menopause-Specific Quality of Life Questionnaire (MENQOL) score from baseline | week 6, 18 and 30 | MENQOL consists of 29 items assessing four domains: VMS, physical symptoms, psychological symptoms, and urogenital/sexual symptoms,with 4 as minimal clinically important differences(MCID). |
| The proportion of participants reporting significantly reduced or moderately reduced based on Global Response Assessment (GRA) | week 3 ,6, 18 and 30 | The response of participants to the treatments are divided into seven grades by GRA: significantly reduced, moderately reduced, slightly reduced, no change, slightly aggravated, moderately aggravated and significantly aggravated. The proportion of participants reporting significantly reduced or moderately reduced are recorded as the response rate of the overall efficacy. |
| The proportion of participants with a reduction of 50% or more on the mean 24-hour HF score from baseline | week 3,18,30 | The mean 24-hour HF score = (1 × number of mild HF + 2 × number of moderate HF + 3 × number of severe HF + 4 × number of very severe HF)/Number of days reported. |
| The proportion of participants with a reduction of 50% or more in the mean 24-hour HF frequency from baseline | week 3,6,18,30 | The mean 24-hour HF frequency = total number of HF reported/Number of days reported. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Participants' expectations of improvement to menopausal associated hot flashes | Baseline assessment week 0 | Participants in the EPN group will answer the following question before the first intervention: Do you think acupuncture will be effective for improving menopausal associated HF? The participants can answer Yes, No, or Unclear. |
