Summary

This trial tests if Low Level Laser Therapy (LLLT) can reduce pain and improve sexual function in women with provoked vestibulodynia (PVD) or PVD with vaginismus. LLLT uses red and infrared light to help repair cells. Low-level laser therapy (LLLT) has been used for various conditions requiring pain relief, inflammation reduction, and tissue repair.

Experimental Treatment

Placebo Group

Group I: Low Level Laser Therapy GroupExperimental Treatment1 Intervention

15 treatments will be provided over a 12 week period using a protocol developed in collaboration with BioFlexTM Laser. Each treatment will last approximately 45 minutes and will include the laser array first being applied to the skin overlying the sacral spine in a horizontal placement then in oblique placement bilaterally (red and infrared light) while a laser probe is applied over the base of the spine (red and infrared light). Next, the array will be applied to the surface of the perineum (red and infrared light) and the focal probe will be applied to painful sites on the perineum. Finally, the infrared light probe will be applied to the skin overlying branches of the pudendal nerve. All the stages will involve use of the same array and probe placement, but at each stage the dosage will be increased according to the BioFlex protocol. During teach treatment session, women will listen to an audio recording of a mindfulness-based meditation on CD through noise cancelling headphones.

Group II: Sham Low Level Laser Therapy GroupPlacebo Group1 Intervention

15 treatments will be provided over a 12 week period using the same protocol developed in collaboration with BioFlexTM Laser, but at an intensity of 1% output for all sites and at all stages. Each treatment will last approximately 45 minutes. At each visit, the laser array will first be applied to the skin overlying the sacral spine in a horizontal then oblique placement bilaterally (red and infrared light) concurrently with a laser probe applied over the base of the spine (red and infrared light). Next, the array will be applied to the surface of the perineum (red and infrared light), followed by treatment at specific painful sites using the red light probe. Finally, the infrared light probe will be applied to the skin overlying branches of the pudendal nerve. Participants randomized to this group will listen to an audio recording of a mindfulness-based meditation on CD through noise cancelling headphones while receiving the sham laser treatment.
