Trial Outcomes & Findings for Effect of Acupuncture on Patient Vulvodynia Outcomes (NCT NCT03364127)

NCT ID: NCT03364127

Last Updated: 2025-05-30

Results Overview

The subject calls the pain intensity a number ranging between the minimum value, 0 and 10, the maximum value. Zero represents "no pain" and 10 represents"pain as bad as it could be". Higher scores mean more pain. The PINS will include three items (pain now, least and worst pain in the past 24 hours), which are used to calculate the average of pain intensity. The PINS with the three items and standardized instructions is part of PAINReportIt® which is an electronic version of the 1970 version of the McGill Pain Questionnaire.

Participant Flow

Four-hundred and fifty women were assessed for eligibility of which 290 did not meet eligibility criteria and 71 declined to participate. Eighty-nine participants were enrolled between February 2018 and September 2022. Participants were recruited from community settings as well as from medical clinics throughout the Chicagoland area, from healthcare provider referrals, and from the National Vulvodynia Association website.

No participants were excluded after randomization and assignment to the groups.

PRIMARY outcome

Timeframe: baseline and after the 10th acupuncture treatment week 5

Population: Participants receiving active acupuncture and placebo acupuncture

The subject calls the pain intensity a number ranging between the minimum value, 0 and 10, the maximum value. Zero represents "no pain" and 10 represents"pain as bad as it could be". Higher scores mean more pain. The PINS will include three items (pain now, least and worst pain in the past 24 hours), which are used to calculate the average of pain intensity.

SECONDARY outcome

Timeframe: baseline and after the 10th acupuncture treatment week 5

Population: Participants receiving active acupuncture and placebo acupuncture.

The Dyspareunia Subscale of the FSFI measures pain with sexual intercourse. The FSFI consists of three items scored using a scale ranging from zero to five. The scores of the three items are then summed and multiplied by a factor of 0.4, resulting in a minimum score of 0 and a maximum score of 6.0, with higher scores indicating less pain with sexual intercourse.

SECONDARY outcome

Timeframe: baseline and after the 10th acupuncture treatment week 5

Population: Participants receiving active acupuncture and placebo acupuncture.

The FSFI is a 19-item, multi-dimensional, self-report measure that measures overall sexual function from six domains of sexual response: desire, arousal, lubrication, orgasm, satisfaction, and dyspareunia. The six subscale scores are measured on a scale of 0-5 for each item. Individual item responses from each of the 6 domains are added together to achieve a domain score and are each multipled by a factor (desire, 0.6; arousal, 0.3; lubrication, 0.3; orgasm, 0.4; satisfaction, 0.4; and dyspareunia, 0.4). These final domain scores are summed to obtain the Total Score of the FSFI, ranging from 2.0 to 36.0, with higher scores indicating better overall sexual function.

SECONDARY outcome

Timeframe: after the 10th acupuncture treatment weekly up to 12 weeks post last acupuncture treatment.

Population: Participants receiving active acupuncture and placebo acupuncture that entered the Duration of Effect phase. Participants with a clinically meaningful reduction in pain intensity (at least 1.5 points) at the 10th acupuncture treatment compared to pretest, will measure Vulvar Pain Intensity weekly until pain returns to pretest or up to 12 weeks after the 10th acupuncture treatment.

The subject calls the pain intensity a number between 0, the minimum value and 10, the maximum value. Zero is "no pain" and 10 is "pain as bad as it could be." Higher scores indicate a worse outcome. The PINS will include one item (vulvar pain intensity). The PINS with vulvar pain intensity and standardized instructions is part of PAINReportIt® which is an electronic version of the 1970 version of the McGill Pain Questionnaire.
