Objectives/Objectifs: At the end of this session, participants will be able to discuss the current state of evidence defining muscle dysfunction in women with provoked vestibulodynia (PVD) and identify priorities for future directions, evaluate the effectiveness of a multidisciplinary approach to treating women with PVD, and provide evidenced based rationale for current best practice strategies when treating women with PVD.
Background/Contexte: PVD is the most common form of dyspareunia (recurrent pain during sexual intercourse) in pre-menopausal women and is commonly treated by pelvic health physiotherapists. PVD affects 12–15% of women and has serious negative effects on sexual functioning, psychological well-being, and quality of life (Arnold et al., 2001). PVD is characterized by severe burning pain felt at the vulvar vestibule when pressure is applied to this area, resulting in painful vaginal penetration during sexual intercourse as well as non-sexual activities such as tampon insertion and gynaecological examinations (Bergeron et al., 2001). Although the etiology of PVD is largely unknown and there remains controversy in the conceptualization of PVD, clinicians and researchers agree that it is a multidimensional condition in which biological, psychological, and social influences play a role, and consideration of all associated factors is necessary for proper management of the condition. It has been suggested that an integrated model taking into consideration the biomedical, cognitive, affective, behavioural, and interpersonal factors associated with sexual impairment be adopted in the treatment of PVD (Bergeron et al., 2009).The fragmentation of scientists into specific disciplines, ongoing classification issues, and lack of sound research designs all impede progress concerning the identification of etiological factors and the development of tailored interventions for women with PVD. In order to progress in the management of a multifactorial condition such as PVD, our research methodologies require expansion and the involvement of cross-discipline approaches.
Relevance/Pertinence: The implementation of a biopsychosocial model in the assessment of women with PVD can help establish a successful management program for women with PVD. Each panelist has extensive experience in identifying dysfunctions associated with PVD and implementing treatment strategies to rehabilitate women with PVD. Each panelist contributes to the biopsychosocial model in a unique and collaborative way. The combination of panelists will create a comprehensive understanding of a multifactorial problem that will directly translate into improved clinical awareness during the assessment phase and will lead to improved clinical outcomes. In addition, future directions for research will be identified and discussed.
Target Population/Population cible: The target audience for this session would be clinicians, educators, and researchers working in the area female pelvic health. The session will offer a multifaceted overview of physical dysfunctions and psychological factors associated with PVD, as well as the current physiotherapy management of PVD. The session content will be appropriate for those who have little background knowledge on PVD as well as those with greater knowledge as the speakers will be presenting on the latest understanding and management strategies for women with PVD.
Supporting Evidence/Résumé des faits: The etiology of PVD is unknown, many factors are suspected to play a role. The pelvic floor muscles have been implicated and pelvic floor rehabilitation appears to be a beneficial treatment (Morin and Bergeron, 2009). However, there is a lack of valid and reliable methods for assessing pelvic floor muscle function (Bergeron et al., 2011). Pelvic floor USI can be used to assess pelvic floor muscle (PFM) morphology and function, and in recent years it has gained popularity amongst physiotherapists in the research and clinical settings. The use of ultrasound imaging in combination with dynamometry and electromyography allows for a comprehensive evaluation of muscle function that can help identify dysfunction and ultimately direct treatment decisions.
Pelvic floor rehabilitation aims to increase awareness and proprioception of the pelvic floor muscles, improve muscle relaxation, normalize muscles tone, increase extensibility of the vaginal tissues, desensitize the painful area, and decrease fear of vaginal penetration (Bergeron and Lord, 2002). Pelvic floor rehabilitation achieves this through the use of education, biofeedback, manual therapy, insertional techniques, as well as electrotherapy modalities. Pelvic floor muscle exercises are the foundation of pelvic floor rehabilitation and are often prescribed to improve muscle control and to promote relaxation. Studies have demonstrated the effectiveness of comprehensive pelvic floor rehabilitation programs (Bergeron et al., 2001; Goldfinger et al.,
2009) and multidisciplinary approaches (Spoelstra et al., 2011; Backman et al., 2008) for the treatment of PVD. A comprehensive program has been shown to be effective in significantly reducing pain associated with intercourse and gynecological examinations, improving sexual function and decreasing pain cognitions, increasing vestibular pain thresholds, normalizing pelvic floor muscle tone and activity, improving relaxation capacity, as well as decreasing pelvic floor muscle contractile responses when a painful pressure stimulus is applied to the vestibule (Bergeron et al., 2002; Goldfinger et al., 2009; Gentilcore-Saulnier et al., 2010).
Physical dysfunction is just one aspect of PVD, it is equally important to consider the cognitive, emotional, behavioral, and interpersonal factors that are associated with PVD when developing treatment programs. Currently, a multidimensional viewpoint in which biological, psychological, and social factors are all seen as fundamental to understanding and treating PVD is accepted by most researchers and clinicians (Goldstein & Burrows, 2008; Weijmar et al., 2005). Cognitive-behavioural therapy (CBT) is a commonly used treatment option for the management of various chronic pain conditions, including PVD. Success rates ranging from 39 to 86% have been reported in several studies in which sex therapy and pain management were combined in a group format (Abramov et al., 1994; Bergeron et al., 2001; Bergeron et al., 2008; Weijmar-Schultz et al.,
1996). Results from a randomized trial indicate that although the effects of group CBT may take longer to present, it is as effective as vestibulectomy in reducing intercourse pain intensity (Bergeron et al., 2001; Bergeron et al., 2008). These results indicate that a directed treatment approach including both cognitive and behavioural techniques for pain management may yield better outcomes and greater satisfaction than a less directive approach.
Overall, there is a need to investigate a variety of treatment options for PVD. There is still much that needs to be investigated in terms of the role of adherence and other factors in predicting and explaining the process of improvements. There is also a need to develop methods for objective quantification of PFM functioning in women with PVD in order to reliably measure functional impairments at baseline and investigate change in PFM components following treatment.
Session Format/formule de la session: Four panelists will present on the management of PVD. Panelist 1 and
2 will report on the most current understanding of muscle morphology and dysfunction in women with PVD based on the evaluation using ultrasound imaging, dynamometry, and EMG. The third panelist will speak to psychological factors and non-medical treatments associated with PVD, as well as highlight interesting findings from studies on pelvic floor rehabilitation in women with PVD and a randomized study comparing pelvic floor rehabilitation with cognitive behavioral therapy. The fourth panelist will examine the current physiotherapy best practice strategies for treating women with PVD. All four will emphasize where the literature stands now and make recommendations for future directions.
