    Author: Fitzwater JB, Kuehl TJ, Schrier JJ.
    Journal: J Reprod Med; 2003 Aug; 48(8):573-7. PubMed ID: 12971135.
    Abstract:
    OBJECTIVE: To evaluate experience with intravaginal electrical stimulation for the relief of pain when used as adjunctive therapy in women with chronic pelvic pain and levator ani spasm. STUDY DESIGN: A retrospective cohort of consecutively treated patients from 1999 and 2000 was identified using billing records. Systematic chart review was completed using standardized data collection forms for all patients receiving electrical stimulation for pain from levator ani spasm. Data collected were objective for major variables and subjective for outcomes. Demographic data were reported as means and standard deviations. Stimulation characteristics were compared using ANOVA. Survival analysis was performed using life table methods. RESULTS: Medical records from 66 consecutive patients treated during an 18-month interval were reviewed. Demographic characteristics included mean age of 38.7 years, 13 years of education and parity of 2. Married women composed 75% of the study group, with 81% white, 10% Hispanic and 9% black. Of the 66 patients studied, 50 had follow-up documentation with an average duration of 14.5 weeks. Overall, 34 patients (52%) demonstrated improvement in pelvic pain following vaginal electrical stimulation. Using survival analysis, 51% of patients had persistent improvement 30 weeks after treatment. There were no differences in age, race, education or parity between patients reporting a sustained benefit of stimulation and those not reporting a benefit. CONCLUSION: Vaginal electrical stimulation may help a selected population of women with pelvic pain due to levator ani spasm.
