Outcome Measures
Primary Outcomes (4)
Mean Change in Hamilton Depression Rating Scale (HAM-D) (17 Item) in Subjects With Bipolar Depression
A multiple choice questionnaire used to rate depression severity. Mean change from pretreatment score. 17 items reflecting depression symptoms are scored on scale of severity; 9 items are scored 0 = Absent 1 = Trivial 2 = Mild 3 = Moderate 4 = Severe 8 items are scored 0 = Absent 1 = Mild 2 = Severe. Items are summed; minimum score is 0, maximum score is 52. Higher scores represent more severe depression.
Once just before and once just after treatment
Mean Change in Hamilton Depression Depression Rating Scale (HAM-D) (17 Item) in Subjects With Major Depressive Disorder
A multiple choice questionnaire used to rate depression severity. Mean change from pretreatment score. 17 items reflecting depression symptoms are scored on scale of severity; 9 items are scored 0 = Absent 1 = Trivial 2 = Mild 3 = Moderate 4 = Severe 8 items are scored 0 = Absent 1 = Mild 2 = Severe. Items are summed; minimum score is 0, maximum score is 52. Higher scores represent more severe depression.
Once just before and once just after treatment
Visual Analog Scale (VAS) in Subjects With Bipolar Depression
Eleven point Likert scales indicating immediate depression state. Mean change from pretreatment score. Participant marks an 'X' on a numbered line anchored by 0 = no depression and 10 = most depressed ever been.
Once just before and once just after treatment
Visual Analog Scale (VAS) in Subjects With Major Depressive Disorder
Eleven point Likert scales indicating immediate depression state. Mean change from pretreatment score. Participant marks an 'X' on a numbered line anchored by 0 = no depression and 10 = most depressed ever been.
Once just before and once just after treatment

Sham (inactive) Treatment BPD
SHAM COMPARATOR20 minutes of sham treatment with the Low Field Magnetic Stimulation Device (LFMS)in bipolar depressed subjects
Active LFMS treatment in BPD
ACTIVE COMPARATOR20 minutes of active treatment with the Low Field Magnetic Stimulation Device (LFMS)in bipolar depressed subjects

Interventions
The LFMS Device is an electromagnetic coil situated on a cylinder with an inside diameter of 13.2 inches. It produces weak electromagnetic fields at a frequency of about 1 kHz; the magnetic fields are less than 30 Gauss and the electric fields are up to 1.43 V/m. Subjects will receive one 20 minute treatment.

Limitations and Caveats
A limitation of the current trial was that it was underpowered to detect moderate but clinically significant benefits of LFMS in diagnostic subgroups.
