NCT01929681

Brief Summary

Objectives: To demonstrate the duration of the antidepressant effect of Low Field Magnetic Stimulation (LFMS)in subjects with bipolar depression. Hypotheses: Investigators expect subjects who receive LFMS to show significant mood improvement one week after the start of a three day course of daily stimulation as compared to subjects who receive sham LFMS. Investigators expect subjects who receive LFMS to show immediate mood improvement over the first treatment as measured by the difference in pre and post-treatment PANAS+ ratings. Investigators expect to show that LFMS will be well tolerated in a three-treatment protocol.

Outcome Measures

Primary Outcomes (2)

  • Long Term Change: Montgomery-Ã…sberg Depression Rating Scale (MADRS)

    The Montgomery-Asberg Depression Rating scale assesses 10 symptom areas of depression during an interview. Each of the 10 items received a score ranging from 0 to 6. The scale has a range of 0-60 for the reported total. A higher score indicates increased depression for all items and for the total. This outcome measure is the change from pretreatment baseline acquired at the screening visit to a follow-up visit 7 days after the first treatment.

    Variable based on screening visit schedule, > 2 weeks.

  • Change Over First Treatment: Positive and Negative Affect Schedule (PANAS) Positive Items Subscale

    PANAS consists of 10 positive and 10 negative valence word items. Items are rated by the participant to indicate their assessment of how they are feeling about this item "right now" on a scale of 1(slightly) or not at all through 5 (extremely). 10 of of the items form a positive affect subscale, in which a higher score indicates increased positive affect, with a subscale range of 10 to 50. 10 of the items form a negative affect subscale, in which a higher score indicates more negative affect, with a subscale range of 10 to 50. This outcome measure is change in the 10 item positive affect subscale. This outcome measure is the difference between the scale administered immediately (\<30min) prior to the first treatment and immediately after (\<30min) the first treatment.

    90 minutes; change immediately (<30min) prior to the first treatment and immediately after (<30min) the first treatment.

Secondary Outcomes (3)

  • Rate of of Change in Daily Improvement Over 3 Treatments: Positive and Negative Affect Schedule (PANAS) Positive Items Subscale

    Over 3 days of treatment

  • Rate of Change Over 3 Treatments: Montgomery-Asberg Depression Rating Scale (MADRS)

    Over 3 days of treatment

  • Rate of Change Over 3 Treatments: Positive and Negative Affect Schedule (PANAS) Positive Items Subscale

    Over 3 days of treatment

Study Arms (2)

LFMS - active treatment

EXPERIMENTAL

Low Field Magnetic Stimulation (LFMS) active treatment Active low field magnetic stimulation treatment applied with the LFMS Device; the device is on and magnetic field stimulation is present.

Device: Low Field Magnetic Stimulation

LFMS - sham treatment

SHAM COMPARATOR

Low Field Magnetic Stimulation - sham treatment Inactive low field magnetic stimulation (no stimulation) treatment applied with the LFMS Device; the device is on, however no magnetic field stimulation is present.

Device: Low Field Magnetic Stimulation

Interventions

Low Field Magnetic Stimulation is an electromagnetic technique. It uses low strength electric fields operating at a high frequency.
