Interventions
DEVICEAcupuncture
Hwato brand disposable acupuncture needles (size 0.30 × 40 mm and 0.30 × 75 mm) and adhesive pads will be used. Acupoints of Ciliao, Huiyang, Shenshu, Guanyuan, Shuidao, Sanyinjiao, Zusanli, Taixi, Hegu, and Taichong will be used for every participants. Those with sleep or mood disorders will also use acupoints of Shangyintang, Shenmen and Neiguan. Those with tenderness points on the abdominal wall will also use Ashi points no more than five. The needles will be inserted to 60-70mm in Ciliao and Huiyang, 6-10 mm in Shenmen and 10-20mm in other acupoints through adhesive pads. Needles will be lifted, thrusted and twirled gently for 3 times (except for Ciliao) to achieve deqi sensation and manipulated every ten minutes during 20-minute maintenance in prone and supine position respectively. Participants receive acupuncture treatment three times a week in the first four weeks and twice a week in the last four weeks.
DEVICESham Acupuncture
Hwato brand disposable placebo needles (with the handle identical to the needles in the acupuncture group and the body at a size 0.30 × 25 mm) and adhesive pads will be used. Acupoints of Ciliao, Huiyang, Shenshu, Guanyuan, Shuidao, Sanyinjiao, Zusanli, Taixi, Hegu, and Taichong will be used for every participants. Those with sleep or mood disorders will also use acupoints of Shangyintang, Shenmen and Neiguan. Those with tenderness points on the abdominal wall will also use Ashi points no more than five. The needles will be inserted into adhesive pads without skin penetration. Needles will be lifted, thrusted and twirled gently for 3 times to mimic real acupuncture. No manipulation will be conducted during 20-minute maintenance in prone and supine position respectively. Participants receive sham acupuncture treatment three times a week in the first four weeks and twice a week in the last four weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of participants with at least 50% reduction of numerical rating scale (NRS) score on average pain. | Weeks 5-8 | Participants will rate their average chronic pelvic pain each week on a 0-10 NRS scale, where 0 refers to no pain and 10 refers to the worst pain imaginable. The final NRS score on average pain is defined as the mean of the average pain scores of the four weeks. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The change from baseline in the numerical rating scale (NRS) score on the worst pain. | Weeks 1-4, 5-8, 9-12, 13-16, 17-20. | Participants will rate their worst chronic pelvic pain each week on a 0-10 NRS scale, where 0 refers to no pain and 10 refers to the worst pain imaginable. The highest worst pain score of the four weeks will be taken as final NRS score on the worst pain. |
| Proportion of participants with at least 30% reduction of numerical rating scale (NRS) score on the worst pain. | Weeks 1-4, 5-8, 9-12, 13-16, 17-20. | Participants will rate their worst chronic pelvic pain each week on a 0-10 NRS scale, where 0 refers to no pain and 10 refers to the worst pain imaginable. The highest worst pain score of the four weeks will be taken as final NRS score on the worst pain. |
| The change from baseline in the interferes score of Brief Pain Inventory (BPI) short form. | Weeks 4, 8, 12, 16, 20 | The Brief Pain Inventory (BPI) short form assesses the degree to which the chronic pelvic pain interferes with activities over the prior week in terms of general activity, mood, walking ability, normal work (including housework), relations with other people, sleep and enjoyment of life using a 0- to 10-point scale (0 \[Does not interfere\] to 10 \[Completely interferes\]). |
| The proportion of participants rates their overall improvement as very much improved or much improved based on the Patient Global Impression-Change (PGI-C) . | Weeks 8 and 20 | The Patient Global Impression-Change (PGI-C) is a 7 point scale depicting a patient's rating of overall improvement. Patients rate their change as very much improved, much improved, minimally improved, no change, minimally worse, much worse or very much worse. |
| The change from baseline in the Female Sexual Function Index (FSFI) score. | Weeks 8 and 20 | The Female Sexual Function Index (FSFI) is a 19-item self-report inventory designed to assess female sexual function, which comprises six domains of desire, arousal, lubrication, orgasm, satisfaction, and pain. |
| The change from baseline in the total and sub scores of Hospital Anxiety and Depression Scale (HADS). | Weeks 4, 8 and 20 | Hospital Anxiety and Depression Scale (HADS) consists of 14 items, divided into two 7 item subscales to reflect a state of generalized anxiety and the depression. The respondent rates each item on a 4-point scale ranging from 0 (absence) to 3 (extreme presence). |
| The change from baseline in the EuroQol-5 Dimensions-5 Levels (EQ-5D-5L) questionnaire. | Weeks 4, 8 and 20 | EuroQol-5 Dimensions-5 Levels (EQ-5D-5L) Questionnaire is used to measure health-related quality of life. It consists of five questions about mobility, self-care, usual activities, pain and discomfort, and anxiety and depression, and a visual analogue scale on the general health state during the day. |
| Proportion of participants with at least 50% reduction of numerical rating scale (NRS) score on average pain. | Weeks 1-4, 9-12, 13-16, 17-20. | Participants will rate their average chronic pelvic pain each week on a 0-10 NRS scale, where 0 refers to no pain and 10 refers to the worst pain imaginable. The final NRS score on average pain is defined as the mean of the average pain scores of the four weeks. |
