Trial Outcomes & Findings for Trial to Evaluate Efficacy of Magnetic Resonant Therapy (MRT) in PTSD (NCT NCT02268084)

NCT ID: NCT02268084

Last Updated: 2021-10-01

Results Overview

Mean change in the PCL-M total scores of subjects from baseline to end of the double-blind treatment phase, compared between active and sham groups. The Post-traumatic Stress Disorder Checklist - Military Version (PCL-M) is a 17-item metric for PTSD symptoms, as defined by the DSM-IV. Each symptom is scored on a scale from 1-5; total scores range from 17 (least symptomatic) to 85 (most symptomatic).

Participant Flow

Subjects were screened for eligibility; subjects with history of seizure disorder, history of intracranial lesion, history of intracranial implant, prior transcranial magnetic therapy, and inability to adhere to the treatment schedule were excluded from the study. Eligible subjects were provided with study consent forms. No medication wash-out was required.

Measure
Active
Magnetic EEG/ECG-Guided Resonance Therapy treatments use a coil to deliver pulsed magnetic fields to the cortex of the brain. Active treatments are administered for 6 seconds/minute for 30 minutes/day, 5 days/week for four weeks (two weeks of double-blind treatment, two weeks of open-label treatment).
Sham
Sham treatment devices simulate the behavior of the active devices by mimicking the same noise and sensation of active treatment without applying the magnetic field. Sham treatments are administered for 6 seconds/minute for 30 minutes/day, 5 days/week for two weeks. Active treatment devices were used for the additional 2 weeks of open-label treatment.

Mean change in the HAMD-17 total scores from baseline to end of double-blind treatment, compared between active and sham The Hamilton Depression Rating Scale (HAMD-17) is a 17-item metric to rate subjects on severity of depressive symptoms. Total scores range from 0-52, with higher scores indicating more severe symptoms; a score of 0-7 is generally accepted to be within normal range (or in remission), while a score of 20 or greater indicates moderate to severe depression.

Mean change in each WHO-QOL domain score from baseline to end of treatment, compared between active and sham groups. The World Health Organization's Quality of Life Index - BREF Version (WHO-QOL) is a metric used to establish the subject's quality of life in four domains: physical health (D1), psychological health (D2), social relationships (D3), and environmental health (D4). Higher scores indicate a more positive quality of life; D1 has a score range of 7-35, D2 has a range of 6-30, D3 has a range of 3-15, D4 has a range of 8-40.
