What this trial studies

This pilot study aims to evaluate the effectiveness of a respiratory training program, known as cardiac coherence, in patients diagnosed with acute stress disorder following a traumatic event. Participants will receive training from a practitioner and will use a smartphone guide along with a diary to track their compliance with the program. The goal is to determine if this approach can prevent the development of chronic post-traumatic stress disorder within three months. The study will also assess the feasibility and acceptability of this complementary therapy for patients.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with acute stress disorder within 3-15 days of experiencing a potentially traumatic event.

Not a fit: Patients with severe cardiac illness, respiratory pathologies, or those currently on specific medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this program could significantly reduce the incidence of chronic PTSD in individuals who have recently experienced trauma.

How similar studies have performed: While the approach of using cardiac coherence is relatively novel, similar studies on breathing techniques have shown promise in managing stress and anxiety.
