Body-based therapies and transcranial magnetic stimulation for posttraumatic stress disorder: a proposed integrative...

Posttraumatic stress disorder (PTSD) remains difficult to treat, with 30-50% of patients retaining their diagnosis after first-line trauma-focused psychotherapies. Body-based therapies (BBTs) and transcranial magnetic stimulation (TMS) have each shown preliminary benefit for PTSD but have not yet been studied in combination. To our knowledge, this is the first proposal to integrate these modalities as a combined therapeutic approach. PTSD involves disrupted coordination across multiple levels of neural organization, from cortical regulatory networks to limbic threat circuits and autonomic systems. BBTs are theorized to engage bottom-up processes, including autonomic regulation and interoceptive recalibration, while TMS operates through top-down modulation of prefrontal-limbic circuitry and large-scale network connectivity. This complementarity suggests that a combined approach could engage a broader range of PTSD-related dysfunction than either intervention alone. This article reviews the evidence and proposed mechanisms for each modality, places both within current models of PTSD neurocircuitry, and examines potential pathways of interaction including neuroplasticity priming and autonomic stabilization. Important risks are also addressed, including autonomic destabilization, unknown optimal sequencing, and the open question of whether mechanistically distinct treatments produce additive benefits. The case for combining BBTs and TMS is presented as a hypothesis warranting further investigation.
