Brief Summary:
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.

Detailed Description:

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:

  1. To assess the change in EEG alpha brain waves in women with CPP after guided imagery sessions with tDCS actual or sham treatments.
  2. To assess the change in pain, urinary symptoms, and quality of life in women after guided imagery sessions with tDCS actual or sham sessions.

Endpoints:

Primary objective/endpoint: Change in alpha wave frequency on EEG after 10 sessions of tDCS and guided imagery, versus 10 sessions of sham tDCS and guided imagery compared to baseline.

Secondary objective/endpoint:

Change in pain levels (0-10) on a Visual Analog Scale (VAS) after 10 intervention sessions and at end of study compared to baseline.

Hypothesis:

The combination of tDCS and Guided Imagery (GI) will enhance patient outcomes, as evidenced by differences in alpha brain wave changes, pain and quality of life (QOL) measures between tDCS actual and sham treatment groups.

Arm Intervention/treatment
Experimental: 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.
Other: Guided imagery plus active tDCS
The subject will be positioned in the sitting/reclining position in a quiet room with the lights dimmed. The tDCS device and audio headphones will be placed on the subject's head. The tDCS device to be used is the Soterix Medical 1X1 device using 2.0 mA of current. The electrodes that will be used will be standard sponge electrodes. The subject will listen to a scripted guided imagery CD specifically developed for women with chronic pelvic pain through the audio headphones. The guided imagery plus active tDCS arm will have tDCS for 20 minutes concurrently with Guided Imagery.

Sham Comparator: 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.
Other: Guided imagery plus Sham tDCS
The subject will be positioned in the sitting/reclining position in a quiet room with the lights dimmed. The tDCS device and audio headphones will be placed on the subject's head. The tDCS device to be used is the Soterix Medical 1X1 device using 2.0 mA of current. The electrodes that will be used will be standard sponge electrodes. The subject will listen to a scripted guided imagery CD specifically developed for women with chronic pelvic pain through the audio headphones. The sham arm will have 30 seconds of tDCS, but after 30 seconds the device will be turned off. The device will remain in place until the subject has listened to 20 minutes of the guided imagery CD.




Primary Outcome Measures :
  1. Change in alpha wave frequency on EEG [ Time Frame: Up to 21 days after the first treatment of tDCS +GI or sham tDCS +GI ]
    Change in alpha wave frequency on EEG between baseline and up to 21 days after the first treatment of tDCS +GI, versus sham tDCS +GI


Secondary Outcome Measures :
  1. Change in pain levels on a 0-10 (no pain to most severe pain) Visual Analog Scale (VAS) [ Time Frame: Up to 21 days after the first treatment of tDCS +GI or sham tDCS +GI ]
    Change in pain levels (0-10) on a Visual Analog Scale (VAS) between baseline and up to 21 days after the first treatment of tDCS +GI, versus sham tDCS +GI
