About

The goal of this randomized controlled trial is to determine whether the use of a novel vibrating pelvic floor therapeutic device ("Kiwi") improves sexual function in sexually active women aged 18 and older with genito-pelvic pain and penetration disorder (GPPPD) more effectively than traditional vaginal dilators.

The main questions it aims to answer are:

1. Does the use of the Kiwi device lead to higher sexual function scores compared to traditional vaginal dilators
2. Does the Kiwi device improve sexual distress, pain, and overall symptom severity more effectively than traditional vaginal dilators?

Researchers will compare the Kiwi vibrating device to traditional cylindrical vaginal dilators to assess whether the Kiwi device results in greater improvements in sexual function and symptom relief.

Participants will:

• Be randomly assigned to use either the Kiwi device or traditional vaginal dilators.
• Use the assigned device three times per week for 15 minutes per session over four weeks.
• Complete surveys before and after the study, including assessments of sexual function, pain, and overall improvement.

Full description

This randomized controlled trial (RCT) aims to evaluate the efficacy of a novel vibrating pelvic floor therapeutic device (the "Kiwi") compared to traditional vaginal dilators in improving sexual function outcomes in sexually active women aged 18 and older with genito-pelvic pain and penetration disorder (GPPPD).

The primary objective is to determine whether the Kiwi device leads to higher Female Sexual Function Index (FSFI) scores after four weeks of use compared to traditional dilators.

Secondary objectives include assessing improvements in:

• Sexual distress (Female Sexual Distress Scale - Desire/Arousal/Orgasm, FSDS-DAO)
• Pelvic pain (Vulvar Pain Assessment Questionnaire, VPAQ-screen subscale)
• Overall symptom severity (Patient Global Impression of Severity, PGI-S)
• Perceived improvement (Patient Global Impression of Improvement, PGI-I)

Participants (n=60) will be randomized into two arms:

1. Kiwi device group - a commercially available vibrating pelvic floor therapeutic product.
2. Traditional dilator group - a standard graduated cylindrical vaginal dilator set.

Participants will use their assigned device three times per week for 15 minutes per session over a four-week period. Data will be collected at baseline and at the end of the study using validated questionnaires.

The study hypothesizes that participants using the Kiwi device will demonstrate greater improvements in FSFI scores compared to those using traditional vaginal dilators, reflecting enhanced sexual function and reduced symptom severity.

Kiwi (Commercially available therapeutic vibrating pelvic floor product)

Experimental group

Description:

Kiwi is a therapeutic vibrating pelvic floor product that includes an option for external massage and stimulation. The V- shaped massager, is designed to bridge anatomical variety and has three main massage ends. 1. The cylindrical end is comparable in application to traditional vaginal dilators. However, one significant difference is its tapered shape; this allows for continuous and gradual diameter increase, as opposed to discrete increments in the traditional dilator sets. The tapered end has an optional vibration mode with 4 different intensity settings. This cylindrical shape can also be used as a tool to apply external pressure point massage to the muscles of the urogenital triangle, such as the perineal muscle and the bulbospongiosus muscles. 2. A wider flat surface area has an additional motor to apply vibration to the glans clitoris. This end can also be used for massage. 3. The rounded bottom end of Kiwi can be used as a broad area massage tool.

Silicone Dilator Arm

Active Comparator group

Description:

A commercially available set of graduated cylindrical vaginal dilators. The standard of care is a 6-piece, progressive-sizing, silicone dilator set. Dimensions of the silicone dilators are (WxH): (1) 0.7"x4.75", (2) 0.9"x5.25", (3) 1.0"x5.45", (4) 1.1"x5.85", (5) 1.3"x6.35", (6) 1.5"x6.85". These dilators are not battery powered, have no buttons, and no removable pieces.
