Pain, psychological distress and motor pattern in women with provoked vestibulodynia (PVD) - symptom characteristics and therapy suggestions

Background and aims: Provoked vestibulodynia (PVD) represent a longstanding pain syndrome that affects large numbers of women worldwide. However, no standardized guidelines for PVD treatment exist. In a cross-sectional pilot study we examined 30 PVD patients on multidimensional parameters including pain, psychological distress and quality of movement, in order to obtain a broader understanding of the somatic and psychological symptoms in PVD, and for the future to develop better interventions. Additionally, we compare the findings to previously published results regarding the same parameters in women with chronic pelvic pain (CPP). Methods: Thirty women with PVD recruited from a tertiary care university clinic of gynecology were assessed for demographic data, pain intensity (VAS), psychological distress (GHQ-30 and Tampa scale of Kinesophobia) and quality of movement (standardized Mensendieck test, SMT). Results: Average age of the PVD women was 24.7 +/- 3.60 years, 60% of them were in permanent relationships, all were nulliparous, none had been subjected to surgical procedures, 100% were working full or part time and 90% were educated to at least undergraduate level. Mean VAS score was 7.77 +/- 1.97 (mean +/- SD), kinesiophobia 24.4 +/- 3.95 and anxiety domain of GHQ-30 9.73 +/- 4.06. SMT scores were particularly low for the domains of respiration and gait (less than 50% of optimal scores). Conclusions: PVD women display reduced quality of movement, especially for gait and respiration patterns, increased level of anxiety and high average pain scores. These findings are similar to what we have previously reported in CPP patients. However, in contrast to CPP group, PVD women are on average younger, have higher work participation, higher education level and have not been subjected to surgical procedures. Implications: Since PVD women display similar, although somewhat less severe, symptom profile than CPP, we suggest that a multidimensional approach to treatment, such as "somatocognitive therapy" should be investigated in this group as it has previously been shown to be promising in treatment of CPP.
