Abstract

Purpose

Several treatment options are proposed for the management of pelvic floor myofascial pain (PFMP). Manual therapy, such as vaginal stretching (VS), is one of these options. Photobiomodulation therapy (PBMT) with a laser device is a treatment option for PFMP that has been tested on other muscles. The aim of this study was to evaluate the effect of VS combined or not with PBMT for PFMP treatment.

Methods

One hundred three women with PFMP were enrolled in a double-blind randomized trial and assigned to VS+PBMT (10 treatments over 2 weeks with 100 mw delivering 12 joules to surface intravaginally, using near-infrared light 808 nm) and VS+shamPBMT treatment groups. Pain severity was assessed by Visual Analog Scale (VAS). Pelvic floor muscle function was assessed by Oxford Scale and surface electromyography. Urinary symptoms were evaluated by ICIQ-OAB and ICIQ-SF questionnaires, and intestinal constipation was assessed by ROMA criteria.

Results

There was a significant improvement in pain intensity (VAS) after treatment in both groups, with no difference between groups (p = 0.46). More than 50% of the women complained of severe pain before treatment, and after treatments, it was reported by less than 20% of women (p < 0.001), with no difference between groups (p = 0.08). Urinary symptoms improved in both groups (p < 0.001) with no difference between groups (p = 0.37). Intestinal constipation improved in the VS+PBMT group only (p = 0.01).

Conclusion

VS and VS with near-infrared vaginal laser therapy were equally effective at decreasing myofascial pelvic pain and reducing urinary symptoms
