A Study of Participants Ages 21-65 Diagnosed With Dyspareunia and the Effects of Low Intensity Shockwave Treatment

Randomized Controlled Trial for Use of Low Intensity Shockwave for Patients With Dyspareunia

Dyspareunia is defined as a complaint of persistent or recurring pain or discomfort associated with attempted or complete vaginal penetration

e purpose of this study is to determine the effectiveness of low intensity shockwave treatment for patients with dyspareunia and their ability to tolerate sexual activity, (i.e., penetration of vagina, self or partnered pleasure).

Participants will:

• Be given a preliminary physical therapy examination and evaluation.
• Be asked to attend weekly low intensity shockwave treatment visits.
• Be asked to complete 3 Month follow up questionnaires

This study seeks to determine the effectiveness of low intensity shockwave (LiSWT) for patients with dyspareunia, with the primary objective being the ability to tolerate penetration of the vagina and sexual activity, (self or partnered pleasure). A secondary objective of the study is an improved quality of life.

This is a single blind, randomized controlled trial, with randomized placebo phase design.

A total of 60 participants enrolled at 4 clinical sites will be blinded to the group they are assigned to, (treatment or sham). Clinical investigators cannot be blinded to treatment or sham in order to deliver the treatment.

There are two arms of the study: the Intervention arm where subjects receive active low intensity shockwave treatment plus typical physical therapy. Intervention is the delivery of shockwaves to the pelvic floor region using Softwave Tissue RegenerationTechnologies OrthoGold 100 MTS OP155 unfocused parabolic probe electrohydraulic device.

The Control arm subjects receive sham shockwave treatment plus typical physical therapy.

Each clinical site will have an envelope with pre-determined even and odd numbers determining randomization. Upon enrollment a random number from the envelope will be drawn and assigned to the participant.

At 4-6 weeks participants in the control arm will be given the option of moving to the shockwave (intervention) arm. Participants will spend 4 to 4 1/2 months in the study receiving treatment once per week, 4-6 weeks duration for both treatment arms. Subjects will then be contacted for a 3-month follow-up by phone completing their study participation.
