NCT02545192

Brief Summary

The investigators propose to make the first observations of LFMS treating a population of subjects with PTSD. A positive outcome for this study could translate directly into a new treatment modality for symptoms of PTSD in both acute and chronic situations. The investigator's goal is to demonstrate the safety and efficacy of LFMS as a possible aid in the treatment of PTSD.

Outcome Measures

Primary Outcomes (2)

  • Change in depression

    Change in depression as measured by the Montgomery Asberg Depression Rating Scale in subjects receiving active LFMS treatment relative to sham treatment

    1 week

  • Change in anxiety

    Change in anxiety levels as measured by the Hamilton Anxiety Rating Scale in subjects receiving active LFMS treatment relative to sham treatment

    1 week

Secondary Outcomes (3)

  • Improvement in core PTSD symptoms

    1 week

  • Daily improvements in short-term measures of depression

    24 hrs

  • Daily improvements in short-term measures of anxiety

    24 hrs

Study Arms (2)

Active LFMS treatment

EXPERIMENTAL

20 minutes of active Low Field Magnetic Stimulation using the LFMS device.

Device: Low Field Magnetic Stimulation

Sham LFMS treatment

SHAM COMPARATOR

20 minutes of sham Low Field Magnetic Stimulation using the LFMS device.

Device: Low Field Magnetic Stimulation

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 1000Hz; the magnetic fields are less than 30 Gauss and the electric fields are up to 1.43 V/m. A fully detailed description of the electromagnetic field distribution and waveform has been presented in the IDE submission to the FDA (and determined to be a non-significant risk device).
