Introduction Physical therapy (PT) may reduce the pain associated with provoked vestibulodynia (PVD) based on previous findings that pelvic floor muscle dysfunction (PFMD) is associated with PVD symptoms. Aims The goals of this study were: (i) to determine whether women with and without PVD differ on measures of pelvic floor muscle (PFM) behavior; and (ii) to assess the impact of PT treatment for women with PVD on these measures. Methods Eleven women with PVD and 11 control women completed an assessment evaluating PFM behavior using surface electromyography (SEMG) recordings and a digital intravaginal assessment. Women with PVD repeated the assessment after they had undergone eight PT treatment sessions of manual therapy, biofeedback, electrical stimulation, dilator insertions, and home exercises. Main Outcome Measures Superficial and deep PFM SEMG tonic activity and phasic activity in response to a painful pressure stimulus, PFM digital assessment variables (tone, flexibility, relaxation capacity, and strength). Results At pretreatment, women with PVD had higher tonic SEMG activity in their superficial PFMs compared with the control group, whereas no differences were found in the deep PFMs. Both groups demonstrated contractile responses to the painful pressure stimulus that were significantly higher in the superficial as compared with the deep PFMs, with the responses in the PVD group being higher than those in control women. Women with PVD had higher PFM tone, decreased PFM flexibility and lower PFM relaxation capacity compared with control women. Posttreatment improvements included less PFM responsiveness to pain, less PFM tone, improved vaginal flexibility, and improved PFM relaxation capacity, such that women with PVD no longer differed from controls on these measures. Conclusion Women with PVD demonstrated altered PFM behavior when compared with controls, providing empirical evidence of PFMD, especially at the superficial layer. A PT rehabilitation program specifically targeting PFMD normalized PFM behavior in women with PVD.

Aims-The purpose of this study was to determine the effect of a 12-week pelvic floor muscle (PFM) training program on urethral morphology and mobility in women with stress urinary incontinence (SUI).Methods-Forty women with SUI were randomly assigned to one of two groups: the treatment group received 12 weekly physiotherapy sessions during which they learned how to properly contract their pelvic floor muscles (PFMs) and a home exercise program was prescribed, reviewed, and progressed; the control group received no treatment. Before and after the 12-week study period, ultrasound imaging was used to evaluate bladder neck position and mobility during coughing and Valsalva maneuver in supine and in standing, as well as urethral morphology. Secondary outcome measures included a 3-day bladder diary, 30-min pad test, the Incontinence Impact Questionnaire (IIQ-7) and the Urogenital Distress Inventory (UDI-6).Results-The women in the treatment group demonstrated reduced bladder neck mobility during coughing and increased cross-sectional area of their urethra after as compared to before the training. These changes were not evident in the control group. No differences in the resting position of the bladder neck or in bladder neck excursion during Valsalva maneuver were noted in either group. Concomitantly the women in the treatment group demonstrated significant improvements in the 3-day bladder diary and IIQ-7 after the PFM training and improved significantly more than the control group.

Introduction Research suggests that increased tension in the pelvic floor muscles of women with provoked vestibulodynia (PVD, the most common form of chronic vulvar pain) may play an important role in maintaining and exacerbating their pain. However, no prospective studies of pelvic floor physical therapy (PFPT) for PVD have been carried out. Aim This study prospectively examined the effectiveness of a PFPT intervention in treating the pain and sexual and psychological components of PVD, and determined predictors of greater treatment success. Methods Thirteen women with PVD completed eight sessions of PFPT. Participants were assessed at pre- and post-treatment via gynecological examinations, vestibular pain threshold testing, structured interviews, and standardized questionnaires. A 3-month follow-up interview assessed any further changes. Main Outcome Measures Outcome measures included: vestibular pain thresholds, gynecological examination and intercourse pain ratings, sexual function and intercourse frequency, mental health, negative pain cognitions, and success rates. Results Following treatment, participants had significantly higher vestibular pain thresholds and significantly lower pain ratings during the gynecological examination. Participants reported significant reductions in pain intensity during intercourse and were able to engage in significantly more pain-free activities. Although overall sexual function significantly improved, various components of sexual function and frequency of intercourse did not. Participants’ mental health did not significantly improve; however, pain catastrophizing and pain-related anxiety significantly decreased. The treatment was considered to be successful for 10 of the 13 participants, and predictors of greater treatment success included greater reductions in helplessness and a longer period of time in treatment. Conclusions Results provide preliminary support for the effectiveness of PFPT in treating the pain of PVD, as well as some of the sexual and cognitive correlates of PVD. The results also indicate the need for large-scale, randomized studies of the effectiveness of PFPT in comparison and in conjunction with other treatment options.

The survey results suggest that WHPTs practising in Canada seek post-professional training with an emphasis on pelvic floor assessment and treatment, obstetrics and gynecology, urogenital concerns, complications of cancer, wellness and health promotion, and research. Future research should focus on the barriers to devoting full-time practice hours to WHPTs.
