140. Nervous System Healing with the Rezzimax PainTuner – Trauma Release, Cranial Nerves & New Research; An Interview with Sharik Peck & Katyrra Larson

In this returning episode of The Concussion Coach Podcast, host Bethany Lewis (The Concussion Coach) reconnects with Sharik Peck and Katyrra Larson to explore the latest developments with the Rezzimax PainTuner—an external vagus nerve stimulator that uses gentle resonance (in the frequency range of a cat's purr) to calm the nervous system. Sharik shares exciting updates, including a new Philippines-based study using the device to help breast cancer patients manage stress, pain, and GI dysfunction, as well as ongoing TMJ research in the US. The conversation dives into innovative applications of the tool: a new mouthpiece attachment for cranial nerve stimulation (helping a brain-injured patient regain speech and focus), and scraping techniques that combine vibration with myofascial release. 

Katyrra provides practical calming strategies for acute anxiety and startle responses (including humming with the tongue between the teeth). Sharik also shares a powerful trauma release protocol (Stress Down Regulation/Resilience program) that combines breathing, flexor engagement, and sensory input to help the brain reorganize traumatic memories—a protocol that does not require the device but is accelerated by it. The episode emphasizes nervous system regulation as the cornerstone of concussion recovery, and Bethany shares her personal enthusiasm for the tool, including a listener discount and money-back guarantee.
