What is the SSP?

Developed by Dr. Stephen Porges, the SSP is a five-day intervention designed to reduce stress and auditory sensitivity while enhancing social engagement and resilience. By calming the physiological and emotional state, the door is opened for improved communication and more successful therapy.

The SSP is a research-based therapy showing significant results in just five days in the following areas:

  • Social and emotional difficulties
  • Auditory sensitivities
  • Anxiety and trauma related challenges
  • Inattention
  • Stressors that impact social engagement

Emotional and physiological state are critical to how we approach the task at hand. So when a client has better state control, not only can they be more socially engaged, they are more open to therapy. Better state regulation improves therapeutic outcomes. Read more about how the SSP is helping clients.

This non-invasive intervention involves listening to music that has been processed specifically to retune the nervous system (regulating state) to introduce a sense of safety and the ability to socially engage. This allows the client to better interpret not only human speech, but, importantly, the emotional meaning of language. Once interpersonal interactions improve, spontaneous social behaviors and an enhanced ability to learn, self-regulate and engage are often seen.

The SSP is available to professionals only. View SSP training information. For ways you can use the SSP at home, please call 303-741-4544.

The SSP is a Patent Pending intervention.

*Training is required before ordering the SSP system which is offered on a subscription basis.



  • Calms the emotional and physiological state by improving vagal regulation of the heart and improving auditory functions
  • Addresses difficulties in social communication


  • One hour of vocal music per day for five consecutive days, may be implemented in 30-minute segments
  • May be implemented by clinician, assistant, caregiver or self-administered in clinic or home


  • Quick and easy to administer
  • Accelerates subsequent therapies

How does it work?

Based on Dr. Porges’ Polyvagal Theory, the program is derived from nearly four decades of research on the relationship between the autonomic nervous system and social-emotional processes. It is designed to stimulate nervous system regulation by exercising and systematically challenging the auditory system with specifically processed music.

The music trains the auditory pathways by focusing on the frequency envelope of human speech. As the client learns to process these speech-related frequencies, they improve the functioning of two cranial nerves that are important for promoting overall social behavior. Cranial Nerve VII (Facial Nerve) helps clients focus on human voice and tune out irrelevant frequencies. Cranial Nerve X (Vagus Nerve) enables self-soothing and autonomic regulation.

Following successful completion of the intervention, individuals will be better able to focus in school, therapy, and everyday life and experience a calmed emotional and physiological state.  This is based on studies that suggest that skills such as attention, state regulation and the ability to engage socially will be enhanced.

Client and Therapist Testimonials

“My stomach has a bit of a smile, with eyes that blink very happy. That’s why I am very happy. I feel free.”

– Bente, 6 year old girl

“This girl and her family have attempted many different therapeutic interventions over the developmental years and unfortunately were discouraged with the outcomes. The positive results on the SSP have provided this family with encouragement and hope.”

– From the therapist of a 15 year old with ASD

“There seems to be a better sense of control about my emotions and a sense of balance and calm. It has been extremely rewarding to be more deliberate and aware of my reactions. This change has improved the communication and conflict resolution in some of my most important relationships.”

– From a 53-year old client struggling with sleep, attention and motivation problems following the death of her husband 1 ½ years ago

Two Peer-Reviewed Studies (involving 292 children)

Respiratory Sinus Arrhythmia and Auditory Processing in Autism: Modifiable Deficits of an Integrated Social Engagement System?

In this peer-reviewed study, higher functioning individuals with ASD were tested using an early version of the SSP.  The study showed that auditory processing and state regulation improved following the intervention.

Reducing Auditory Hypersensitivities in Autistic Spectrum Disorder

In a second peer-reviewed study, children with Autism Spectrum Disorder (ASD) who used an early version of the SSP experienced significant improvements in emotional organization, listening, spontaneous speech and hearing sensitivities.

5 clinical trials in progress to evaluate the effectiveness of the LPP/SSP in:

  1. Children with a trauma history. Funded by the Australian Childhood Foundation.
  2. People with ADD who have difficulties with autonomic and/or behavioral regulation. In cooperation with: ADD Centre and Biofeedback Institute of Toronto.
  3. Emotionally disturbed and learning-challenged young people who have difficulties with autonomic and/or behavioral regulation. Funded by the Reiss-Davis Child Study Center of Vista Del Mar, California.
  4. Decreasing the atypical features of the Social Engagement System in adolescents with Prader Willi Syndrome. In cooperation with the Latham Centers School in Brewster, Massachusetts.
  5. Reducing chronic pain in a sample of older adults. In cooperation with the Meadowood Retirement Community in Bloomington, Indiana.

“Collectively, the data from the current trials and Porges et al. provide convergent preliminary support that LPP (precursor to the SSP) enhances function of the Polyvagal “social engagement system” manifested in improved auditory processing, reduced auditory hypersensitivities, increased vagal regulation of the heart, and increased spontaneous social behaviors (e.g., sharing).”
