Rhythmic Entrainment Intervention™ (REI) is an auditory brain stimulation program that uses musical rhythm to stimulate and re-pattern neurological function. A unique blend of modern advances in brain research and ancient rhythmic techniques, REI facilitates long-term behavioral and cognitive improvement in individuals with neurological disorders.
REI was borne out of ethnomusicological research REI creator Jeff Strong began in the early 1980’s. For over a decade Mr. Strong immersed himself in time-tested rhythmic techniques, studying with traditional practitioners from around the world. He then extracted the core mechanisms of these techniques and began researching them in a controlled setting.
After 11 years of extensive clinical and scientific research, including several double-blind, placebo-controlled studies, Mr. Strong and the Strong Institute research staff identified hundreds of rhythmic combinations that correspond to specific behavioral and cognitive symptoms. This research resulted in two important findings:
The REI Custom Program was created in 2004. Careful collection and analysis of data have allowed the composition, protocols and efficacy of the program to continually evolve. The current REI Custom Program is the most effective presentation of REI to date.
We learned early on while developing the REI Custom Program that each person responds to a different type and level of stimulus. Our first formal institutional study in 1994 used custom-made recordings, employing the same protocol as our earliest research. That is, REI creator Jeff Strong performed live for each subject while the listener's responses were tracked. A recording was made based on this data. This recording was then played once a day and adjusted as the listener progressed.
This process has varied only slighty in the last 2 decades. Though Jeff rarely performs live for a client, our focus on customization is stronger than ever: We ensure you receive the progressive stimulation that meets your needs.
As you complete the REI Custom Program Intake process, we identify the major issues you face and create a map of the appropriate stimulation to meet your goals. We use sophisticated algorithms to assemble the proper rhythms for your first REI Audio Track; each subsequent track is created in 10-day intervals according to your progression through the program.
This ensures the most efficient and effective program possible. Indeed, this is where we excel: Custom stimulation for optimal client improvement.
Since 1994, the REI Custom Program™ has been used successfully by tens of thousands of people from around the world. Our clientele consists of both children and adults who come to us with a variety of conditions, including:

"I can't express how grateful we are for the REI Custom Program. Our son didn't sleep for YEARS until he started listening to your music. I have to admit the concept sounded a bit like snake oil at the beginning but now I am a true believer. I sing your praises to anyone who mentions sleep issues. Kids with autism (and their parents) have many challenges every day and it is so difficult to make progress when completely exhausted. It's 7am and our son is still sleeping!! Wahoo!" Jenn L, Mother of a 5 year-old with autism
“I would definitely recommend (the REI Custom Program™), absolutely. I think the children that have these certain issues benefit from all kinds of therapies and interventions and this is one we’ve seen-- like I said, the fog has lifted in so many ways. He seems so much sharper." Nancy D. Mother of a 7 year-old with PDD
“Her frustration level has improved greatly… Her concentration has improved. She’s more willing now to try new things. [It] makes a difference. Also her writing has improved… It was pulling together; I couldn’t believe it.” Maureen B. Mother of 14 year-old girl with Autism
“When we had the CD made, we put it in while he was in a session with his craniosacral therapist. He responded instantly! His system was calming down, and to the surprise of his therapist, he started vocalizing. …We went from nothing to something with vocalizing… He is now starting to put sentences together, and I’m very pleased.” Leslie J. Mother of a 19 year-old with autism
“There are real positive changes. He actually gave me a REAL hug – without prompting. His hugs are usually a little pat on the back… He is more polite, easier to talk to, more attentive, and more focused. He’s a pleasure to be around.” Linda M. Grandmother of a 14 year old with ADD and Oppositional Behavior
“We would definitely recommend the REI Custom Program™ to other parents with children on the Autism Spectrum. We tried other therapies including the Gluten/Casein Free Diet and the Tomatis Listening Program with mixed results. We have definitely seen improvements with our son while on the REI Custom Program.” David S. Father of a 9 year-old with autism
"I'm focusing better and getting a lot more done at work [since starting REI]. I can stay with a project a lot longer without climbing out of my skin. I'm also falling asleep easier and waking up much earlier in the morning." Josh B. 22 year-old with ADD and sleep issues
"Since beginning the REI Program, My husband is less forgetful, more organized, and more cheerful. He's whistling for the first time in years, a sign that he's happy. He's taking the initiative to play his CDs everyday. I'm so grateful to have my old husband around again." Barbara Z. Wife of 67 year-old with AD/HD and mood issues
"Rhythmic Entrainment Intervention is the best intervention we‘ve tried for our son. Thank you for making this therapy available!" Helen G. Mother of a 9 year-old with autism
“[My REI Custom Program] definitely helps me with falling asleep more quickly, better quality of sleep, and more energy to face the day. I really feel the differences, day to day. [I’m] less anxious, more awake, more centered. I feel more of a sense of groundedness...” Kristen K. 28 year-old with sleep and anxiety issues
“After just one week using the REI Custom Program, I’m sleeping like a rock -- and I do have sleep issues!” Lisa M. 53 year-old with sleep and anxiety issues
“Our daughter has had very few temper tantrums. She is also developing the ability to stop herself and calm herself down, usually within about one minute of when the recording starts. She’s been getting along much better with her brothers and sisters. Her attention span has increased--she can sit quietly and read a book for longer periods of time. She’s paying attention more in school and staying on task.” Lisa D. Mother of an 8 year old with AD/HD
“Overall, our son is much calmer, a lot less impulsive and interacts with others much more frequently. For the first time he seems to realize he’s not separate from the rest of the world. His eye contact has improved dramatically. His tantrums are fewer and when he does have a tantrum, they are more like outbursts of emotion rather than anger and defiance. He hasn’t had any panic attacks in the past two months. At the beginning (of the REI Custom Program™) he didn’t even seem to realize that speech has a purpose. He has gone from saying only one or two words a day at the beginning to about 30 or 40 a day now. His pronunciation has also improved. He now seems to realize that speech has a purpose, and he has been putting a lot of effort into talking.” Diane A. Mother of a 7 year-old with autism
“I’m sleeping, dreaming and waking up fresh. My depression has lifted completely. Although I’m 52, I’m feeling like I’m back at 27. Thank you for giving me my life back!" Marsha M. 52 year-old with sleep and mood issues
