Clinical Results

What can a DSB treat?
- Post-Traumatic Stress Disorder
- Anxiety
- Long-COVID

Post-Traumatic Stress Disorder (PTSD) is brought on by a physically or emotionally traumatic life event. Today, the CDC defines trauma as an experience marked by a sense of horror, helplessness, serious injury, or the threat of serious injury or death.

Anxiety refers to persistent feelings of fear and dread that are not always triggered by a single, identifiable source. Anxiety often prompts physical changes, like: increased blood pressure, rapid heart rate, excessive sweating, dizziness, headaches, pain, and sleep irregularities.

Some common Long COVID symptoms—fatigue, oxygen deficiency, and brain fog—are related to nervous system dysfunction. By bringing the nervous system down from a heightened fight-or-flight state, DSBs can rapidly alleviate nervous system-related symptoms.
