About this study

This study is not intended to be definitive and should be considered an exploratory randomized trial to determine conditions for which microcurrent is more effective. Thus, extensive subgroup analyses will be performed so that definitive trials can be developed. This is a double-blind study where subjects will not know if they are receiving microcurrent treatment.

Day 0, Screening visit (may occur during the patient's regular health visit):

  • Obtain and document signed Informed Consent document and HIPAA Authorization.
  • Review past medical history to verify inclusion/exclusion criteria.
  • Proper hydration is essential before any microcurrent therapy. Hydration is ensured by the patient drinking at least 8 ounces of water 1 hour before treatment.
  • Record onset and chronicity of fibromyalgia syndrome
  • Record any medicines that the subject is taking.
  • Collect demographic information to include age, weight (pounds), height (inches), race, ethnicity, and sex.
  • Record any standard treatment subject is receiving. Standard treatment may include, but is not limited to one or more of the following: medications, physical therapy, acupuncture, pain management clinic, dry needling, occupational therapy, osteopathic manipulative treatment,

Randomization: Subjects will be randomized using complete block design with repeated measure into one of two research-related treatment groups: Group 1 (microcurrent) and Group 2 (placebo microcurrent)

Day 1 (may be same day as screening):

  • Subjects will complete the following pre-treatment:
  • Measure Yourself Medical Outcome Profile (MYMOP)
  • Revised Fibromyalgia Impact Questionnaire (FIQR)
  • Pre-treatment measurement of active range of motion of both wrists, knees, trunk, neck, and head with the Myovision 3G Wireless System (Myovision, Seattle, WA) ¹ .

--*(Myovision will be performed for some subjects based off the availability of Myvision trained staff)

  • Proper hydration is essential before any microcurrent therapy. Hydration is ensured by the patient drinking at least 8 ounces of water 1 hour before treatment.
  • Research participant will receive microcurrent according to their randomization group.
  • Post-treatment measurement of active range of motion of both wrists, knees, trunk, neck, and head with the Myovision 3G Wireless System (Myovision, Seattle, WA) ¹ .
  • Research participant will be loaned a microcurrent box to bring home with them for this study. They will be instructed to bring the microcurrent box back. A hand-receipt will be signed by the patient accepting responsibility for device replacement if they fail to return or break it.

Day 2-7 (at home microcurrent application):

-The research participant will self-administer the microcurrent according to their randomization group daily.

Day 8:

  • Subjects will complete the following pre-treatment:
  • MYMOP
  • Revised Fibromyalgia Impact Questionnaire (FIQR)
  • Pre-treatment measurement of active range of motion of both wrists, knees, trunk, neck, and head with the Myovision 3G Wireless System (Myovision, Seattle, WA) ¹ .

Treatment and study plan

Microcurrent Transcutaneous Electrical Nerve Stimulator (TENS) for pain relief

Device
  • Duration: 60 minutes.
  • Electrode placement: There will be one lead placed on the back of the neck and one placed on lower abdomen.
  • Frequency: Each lead delivers a dual channel microcurrent of 10 and 40 Hz simultaneously.
  • Amperage: Adjusted according to BMI: 100 μA for an underweight BMI less 20, 300μA for an overweight BMI greater than 30, and 200μA for normal BMI (20-30). Amperage may be adjusted to 20-300 μA according to comfort.
  • Positioning: The patient remains seated for the first 10 minutes with the investigator watching for any side effects. The patient may stand, sit, lie supine, et cetera for the remainder of treatment.

PLACEBO Microcurrent Transcutaneous Electrical Nerve Stimulator (TENS) for pain relief

Primary outcomes

  1. Revised Fibromyalgia Impact Questionnaire (FIQR)

    Time frame: Day 1

    The FIQR assesses three domains (function, overall impact and symptoms) from which a total score of pain impact is derived. FMS patients have a mean (SD) total score of 56.6 (19.9) and healthy patients have a mean (SD) total score of 12.1 (11.6). FMS patients' means for function, overall impact and symptoms domains are 15.6, 11.0, and 30.0 respectively. Higher total scores are indicative of greater dysfunction or symptom severity. While total scores are slightly negatively skewed favoring severe cases, scores can be assessed with parametric methods.

  2. Revised Fibromyalgia Impact Questionnaire (FIQR)

    Time frame: Day 8

    The FIQR assesses three domains (function, overall impact and symptoms) from which a total score of pain impact is derived. FMS patients have a mean (SD) total score of 56.6 (19.9) and healthy patients have a mean (SD) total score of 12.1 (11.6). FMS patients' means for function, overall impact and symptoms domains are 15.6, 11.0, and 30.0 respectively. Higher total scores are indicative of greater dysfunction or symptom severity. While total scores are slightly negatively skewed favoring severe cases, scores can be assessed with parametric methods.

  3. Revised Fibromyalgia Impact Questionnaire (FIQR)

    Time frame: Day 15

    The FIQR assesses three domains (function, overall impact and symptoms) from which a total score of pain impact is derived. FMS patients have a mean (SD) total score of 56.6 (19.9) and healthy patients have a mean (SD) total score of 12.1 (11.6). FMS patients' means for function, overall impact and symptoms domains are 15.6, 11.0, and 30.0 respectively. Higher total scores are indicative of greater dysfunction or symptom severity. While total scores are slightly negatively skewed favoring severe cases, scores can be assessed with parametric methods.

  4. Measure Yourself Medical Outcome Profile (MYMOP)

    Time frame: Day 1

    The MYMOP employs a 7-point scale (0=as good as it could be, 6=as bad as it could be) for individual items of Symptoms, Activity, and Wellbeing as well as the MYMOP profile score. Normative values are neither available nor meaningful for the MYMOP as it is individual to each patient; however, a clinically meaningful change is considered to be a change in the scores of more than 1. The MYMOP scales are ordinal and will be assess with nonparametric methods.

  7. active range of motion (AROM)

    Time frame: day 1 immediately pre-treatment

    AROM (degrees) will be measured for both wrists, knees, trunk, neck, and head using the Myovision 3G Wireless System. The data is interval and will be assessed with parametric methods.

    MyoVision System: MyoVision DynaROM (Dynamic Range Of Motion) is a functional and objective soft tissue injury test that measures muscle guarding and range of motion by assessing both while a patient moves. Data is sent to computer software and graphed for interpretation. DynaROM is FDA cleared, class II diagnostic equipment.
