简要总结
This is a single blind, randomized controlled pilot trial of transcranial direct stimulation (tDCS) intervention or tDCS sham administered with a standardized guided imagery intervention. Up to 25 adult women with chronic pelvic pain will be enrolled and randomized (like a flip of the coin) to achieve a total sample size of 20 women. 10 women in one arm of the study will receive guided imagery with tDCS stimulation. 10 women in the other arm of the study will receive guided imagery with sham tDCS. Subjects will remain blinded until the end of the study.
详细描述
Chronic pelvic pain (CPP) is a common and often debilitating problem among women. It occurs below the umbilicus and is severe enough to cause functional impairment or require treatment. One of the challenges of treating women with CPP is that a single cause is often lacking. CPP presents as a syndrome of symptoms involving gynecologic, gastrointestinal, urologic, and musculoskeletal symptoms as well as psychosocial conditions such as depression that negatively impact quality of life.
The study will consist of one screening visit that may be divided into two visits if needed to accommodate subject's schedules. The screening visit(s) should take place within four weeks prior to starting the intervention schedule. The following will be completed at the screening visit(s): pelvic/levator exam, body mass index (BMI), last menstrual period, medication use, electroencephalogram (EEG), questionnaires (CAGE-AID Questionnaire, Beck Depression Inventory, Interstitial Cystitis Symptom/Problem Index, Generalized Anxiety Disorder 7 item scale, McGill Pain Questionnaire, Pain Catastrophizing Scale, Visual Analog Scale for pain). The subject will complete 16 intervention visits over 12 weeks.
The study intervention visits will be conducted on the Beaumont Hospital- Royal Oak campus by licensed nurses and/or physicians. The initial 10 sessions will occur Monday through Friday, within a 21-day period (allowing for missed days due to unexpected emergencies and/or inclement weather). Excluding weekends, there should be no more than 2 days between the intervention sessions. Each intervention is 20 minutes in duration. After completing the initial 10 sessions, subjects will complete an additional 6 weekly maintenance sessions according to treatment group.
Objectives:
- To assess the change in EEG alpha brain waves in women with CPP after guided imagery sessions with tDCS actual or sham treatments.
- To assess the change in pain, urinary symptoms, and quality of life in women after guided imagery sessions with tDCS actual or sham sessions.

排除标准
- •Pacemaker

- •History of head injury resulting in more than a momentary loss of consciousness during the last 2 years
- •Note: For the sake of preserving scientific integrity, one or more of the eligibility criteria have been left off the list posted while the trial is ongoing. A full list of eligibility criteria will be posted upon completion of the trial.
研究组 & 干预措施
Guided imagery plus active tDCS
Subjects will receive 2 milliamps of electrical stimulation to the brain (transcranial direct stimulation-tDCS) for 20 minutes concurrently while listening to a guided imagery CD specifically designed for women with chronic pelvic pain.
干预措施: Guided imagery plus active tDCS (Other)
Guided imagery plus Sham tDCS
Subjects will receive 2 milliamps of electrical stimulation to the brain (transcranial direct stimulation-tDCS) for only 30 seconds and then the device will be turned off. The device will remain in place, however, for 20 minutes while the subject listens to a guided imagery CD specifically designed for women with chronic pelvic pain.
干预措施: Guided imagery plus Sham tDCS (Other)
