REI - Rhythmic Entrainment Intervention

 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.

Specific rhythms and techniques facilitate improvements in many of the symptoms associated with a variety of neuro-developmental disabilities such as autism, ADHD, and learning disabilities.

Origins of Rhythmic Entrainment Intervention

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:

  • Exposure to specific musical rhythm patterns elicits immediate calming and focusing effects.
  • Repeated exposure to these rhythms results in long-term behavioral and cognitive improvements.

Those who have benefited from REI:

Those who have benefited from rhythmic entrainment intervention program consists of both children and adults who come to us with a variety of conditions, including:
