Non-surgical interventions for the management of chronic pelvic pain

Chronic pelvic pain in women: an epidemiological perspective

Chronic pelvic pain (CPP) is common in women of reproductive age and has a significant impact on quality of life, work efficiency and healthcare utilization. CPP can be a manifestation of many different, often multifactorial conditions, and in the absence of an identified cause, the management can be particularly challenging. High quality epidemiological studies would improve the understanding of CPP and identify risk factors which may be targeted for the development of appropriate management strategies. This review focuses on what is known about the prevalence, risk factors, individual and societal burden of CPP and outlines important management strategies.

Prevalence and use of complementary health approaches among women with chronic pelvic pain in a prospective cohort study

OBJECTIVE

The aim of this study was to examine the prevalence of and factors associated with use of complementary health approaches among women with chronic pelvic pain (CPP).

DESIGN

We analyzed data from the Study of Pelvic Problems, Hysterectomy, and Intervention Alternatives, a prospective cohort study of women seeking care for noncancerous pelvic problems with intact uteri at enrollment. Among a subset of 699 participants who reported having CPP, we analyzed the prevalence of complementary health approaches used and associated patient sociodemographic and clinical characteristics, health-related quality of life, attitudes and beliefs, and conventional health care practices.

RESULTS

At baseline, slightly over one-half (51%) of women with CPP used at least one complementary health approach in the past year, including acupuncture (8%), special foods or diets (22%), herbs (27%), and vitamins and minerals (29%). During follow-up surveys conducted annually for 4 years, a substantial proportion of women (44.8%) used complementary health approaches at more than half of the assessments. Users of complementary health approaches were more likely to undergo a hysterectomy or oophorectomy or to use gonadotropin-releasing hormone agonists or opioids during the study compared with nonusers. Women with CPP who used complementary health approaches also had more optimal health-related quality of life measured by the Pelvic Problem Impact Questionnaire (31.6 vs 25.6, P < 0.001).

CONCLUSION(S)

Many women with CPP consistently use complementary health approaches. The substantial interest in and high prevalence of complementary health approaches used alongside conventional medical approaches highlight the need for better understanding of multimodal approaches to address the complex condition of CPP.

A pilot randomized trial of levator injections versus physical therapy for treatment of pelvic floor myalgia and sexual pain

INTRODUCTION AND HYPOTHESIS

Our aim was to determine the effects of pelvic floor physical therapy (PT) and levator-directed trigger-point injections (LTPI) on sexual function and levator-related pelvic pain.

STUDY DESIGN

A randomized trial among women with pelvic floor myalgia (PFM) was performed wherein participants received either PT or LTPI. Pain was assessed and 1 month posttreatment completion. Levator-based pain was assessed using a numeric rating scale (NRS) and the Patient Global Impression of Improvement (PGI-I) scale. Sexual function was assessed using the Female Sexual Function Index (FSFI).

RESULTS

Twenty-nine women completed the study (17 had PT, 12 had LTPI). Both groups reported reduction in vaginal pain: mean NRS change from baseline of 4.47 [standard deviation (SD) 2.12) for PT and 4.67 (SD 1.72) for LTPI (p = 0.8)]. A >50 % improvement in NRS was documented among 59 % of women receiving PT and 58 % receiving LTPI (p = 1.0). Consistent with NRS scores, mean PGI-I score was 2.50 (SD 1.17) for PT and 2.17 (SD 1.01) for LTPI (p = 0.5). Mean change in FSFI favored PT [PT +8.87 (SD 5.60), LTPI +4.00 (SD 5.24), p = 0.04], reflecting improvement in the sexual pain domain favoring PT (p = 0.02). However, the time in weeks to effect improvement favored LTPI if controlling for the degree of change in NRS (p = 0.01) and FSFI (p = 0.01).

CONCLUSIONS

Vaginal myalgia and sex-related pain improved with pelvic floor PT and LTPI. Time-to-effect improvement and significance of therapy are dependent on treatment type.
