Study of the Acute Effects of Guided Imagery and tDCS on Pain Levels in Women With Chronic Pelvic Pain
A Randomized, Single Blind, Exploratory Study of the Acute Effects of Guided Imagery and Transcranial Direct Current Stimulation (tDCS) on Electroencephalogram (EEG) Alpha Brain Waves and Pain Levels in Women With Chronic Pelvic Pain

Detailed Description
Chronic Pelvic Pain (CPP) is a common and often debilitating problem among women. CPP is pain that is felt below the belly button and is severe enough to cause feelings of pressure, pain while sitting or standing for long periods of time, pain with intercourse, painful urination, and pain with bowel movements. Transcranial Direct Current Simulation (tDCS) is a non-invasive brain stimulation technique. As tDCS modulates nerve activity and connectivity, it is also expected to cause measurable changes in brain activity. Guided imagery is a form of hypnosis using words to direct one's thoughts and attention to imagined sensations. Guided imagery has demonstrated efficacy in reducing pain related to many conditions including cancer pain, chronic lower back pain, and post-operative pain. More information is needed to evaluate the effects of tDCS and guided imagery in the treatment of chronic pelvic pain.
The study will consist of one visit. After informed consent is obtained, the following will be collected/completed: health history, demographics, vitals, and questionnaires (BDI, CAGE-AID, PCS, and VAS for pelvic pain). A urinalysis will be collected to assess for infection and a urine pregnancy test for women of child bearing potential. If a subject qualifies they will be randomized. Before treatment, subjects complete an EEG. Treatment will be delivered based on randomization group assignment. After treatment an EEG, VAS, GRA will be collected. Study staff will assess for adverse events during and after treatment.

Description
Inclusion Criteria:
- Female
- Age 18 to 64 years
- Women must either be unable to become pregnant (surgically sterile or postmenopausal) or must use an approved method of birth control throughout the study period.
- Self-reported CPP defined as pelvic pain that is not related to menstrual cycle and of at lease 6 months duration and refractory to other treatments.
- Subject agrees to not start any new treatments (medication or otherwise) throughout the study participation.
- Subject agrees to maintain stable doses of all current medications throughout study participation.
Exclusion Criteria:
- History of seizures during the last 2 years or diagnosis of epilepsy
- Pacemaker
- Use of carbamazepine, oxcarbazepine, phenytoin, pramipexole or cabergoline within the past 6 months as self-reported
- Parkinson's Disease
- Any condition, including neurological or psychiatric illness, which per investigators' judgment, may increase subject risk
- History of Hunner's lesions
- Lactation, pregnancy, or refusal to use medically approved/reliable birth control in women of child-bearing potential
- Sacral or pudendal Interstim or spinal cord stimulator that is "on"
- Contraindications to tDCS stimulation (e.g. metal in the head, implanted brain medical devices, scalp wounds or infections, etc.)
- History of head injury resulting in more than a momentary loss of consciousness during the last 2 years
Deferral Criteria
- If a subject has a confirmed UTI, she will be deferred until treatment is completed and symptoms resolve
- Participating in another intervention study, or received an investigational drug or device within 4 weeks prior to screening
- Subject received bladder hydrodistention within the past 12 weeks
- Within the past 4 weeks, initiation of any new medications or any intravesical treatment for treatment of IC/BPS
- Within the past 24 weeks received any surgery or procedure which may impact the pelvic floor
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Active tDCS with guided imagery
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.
|
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 20 minutes of stimulation with 25 minutes of guided imagery.
|
EXPERIMENTAL: Active tDCS alone (no guided imagery)
Subjects will receive 2 milliamps of electrical stimulation to the brain (transcranial direct stimulation-tDCS) for 20 minutes while remaining seated, no guided imagery will be provided.
|
The subject will be positioned in the sitting/reclining position in a quiet room with the lights dimmed.
The tDCS device 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.
Active tDCS arm alone without guided imagery, will have 20 minutes of tDCS stimulation without guided imagery.
|
SHAM_COMPARATOR: Sham tDCS with guided imagery
Subjects will receive 2 milliamps of electrical stimulation to the brain (transcranial direct stimulation-tDCS) for only 30 seconds and then the device will turn off.
The device will remain in place, however, for 25 minutes the subject listens to a guided imagery CD specifically designed for women with chronic pelvic pain.
