Summary

Posttraumatic Stress Disorder (PTSD) is a common and serious condition affecting many Veterans. There are effective treatments for PTSD, but additional treatments are needed in order to better serve Veterans suffering from PTSD. Transcranial magnetic stimulation is one such promising treatment. It involves use of powerful magnet to stimulate the specific brain regions in Veterans with PTSD. Transcranial magnetic stimulation has been shown effective in treating depression, but currently it is unclear if it is an effective treatment for PTSD. This is a randomized clinical trial enrolling 91 Veterans with PTSD comparing the effectiveness of transcranial magnetic stimulation treatment and sham transcranial magnetic stimulation in treating PTSD. The hypothesis is that those who receive transcranial magnetic stimulation will experience improved functioning.

Detailed description

Background Posttraumatic Stress Disorder (PTSD) is an often chronic and disabling condition prevalent in the Veteran population. While there is sufficient evidence to demonstrate the effectiveness of medications and psychotherapy for improving PTSD symptoms, there has been limited study of functioning as an outcome, and the role of other treatments such as somatic therapies. One promising but understudied somatic treatment for PTSD is repetitive transcranial magnetic stimulation (TMS). The characteristics of TMS treatment are different than those of existing treatments and may provide alternative treatment to Veterans who do not respond to medications and psychotherapy. Further, it is possible that TMS may have a greater effect on functioning and lead to higher rates of recovery compared with medications or psychotherapy. Objective To determine whether Veteran participants with PTSD who receive TMS delivered to the right dorsolateral prefrontal cortex at 1 Hz have greater improvements in: PTSD symptoms, functioning, and depressive symptoms than Veterans receiving sham treatments at treatment completion and at 3 and 6 months after treatment completion. Method 91 Veterans with PTSD will be randomly assigned to receive low frequency TMS or sham TMS. All TMS will be applied to the right dorsolateral prefrontal cortex. PTSD symptoms, functional outcomes, and depressive symptoms will be measured for all participants at treatment completion, 3 months, and 6 months after completion. Hypothesis Veterans with PTSD receiving TMS will have greater improvements in PTSD symptoms, functioning, and depressive symptoms at treatment completion and at three and six months after treatment completion compared to Veterans receiving sham TMS.

Interventions

Type	Name	Description
DEVICE	TMS 1 hz	High-performance magnetic stimulator designed for clinical use or use in clinical trials. This specific device has a coil designed with one side that delivers active treatment and the other side that delivers sham (no stimulation) treatment. The sham side is externally identical to the active side, but internally it has a shield that prevents any magnetic energy from interacting with the patient. This arm will use the active side.
