A Pilot Study of Integrated Listening Systems for Children with Sensory Processing Problems (Download as PDF) iLs PDF Document

Sarah A. Shoen, PhD, OTR, Lucy J. Miller, PhD, OTR, and Jillian Sullivan, PhD
Journal of Occupational Therapy: Schools and Early Intervention, 8: 1-21 2015
Summary: This study explores the effects of iLs on individualized parent goals for children with sensory processing impairments.  The 40-session iLs program was implemented at home and in clinic over a 3-month period. Important and clinically meaningful gains were achieved by all participants in both home and educationally-related goals.  Individualized goal achievement was supported by gains in standardized measures of behavior and adaptive functioning. Changes in physiological arousal (measured by EDA – electrodermal activity) suggest the iLs program is impacting underlying regulation mechanisms that may be contributing to the observed behavioral changes.  Behavioral changes included increased relaxation, fewer meltdowns and a generally calmer disposition for participants whose arousal decreased.

A Study of Non-Pharmacological Sleep Intervention Study (Download as PDF )

Sharon A. Gutman, PhD, OTR, FAOTA, Associate Professor, Columbia University Medical Center
Summary:  The purpose of this study is to determine the effectiveness of two non-pharmacological interventions for people who experience disordered sleep but do not have a medical problem causing the sleep disturbance. The study will compare the effectiveness of the iLs Dreampad audio pillow and the iRest yoga meditation method in a 2-week intervention period with healthy adults ages 25-65. Status: in progress.

Abstract: A controlled study involving 64 K-2 at risk students was conducted by U of New Mexico researcher Anne Calhoon, Ph.D. Students participated in the Alpha Program,* a program combining iLs with art therapy. The average improvement in reading over the 3-month intervention was 2 years.

An Investigation to Evaluate the Benefits of the Integrated Listening Systems (iLs) in Primary/Early Elementary Classrooms (K-3): The Case of Valley View Academy in Northern California(Download as PDF )

Jeannie Dubitsky, Ed. D., University of California, Davis, 2014
Abstract: Ten students were measured over an academic year of using iLs while at school. Students showed improvement in all areas evaluated – physical, academic, social and emotional development – after experiencing the iLs program.

iLs Home Program Autism Study (Download as PDF) iLs PDF Document

Theresa May Benson, PhD, OTR/L
Abstract: Study on the effect of the iLs home program on 18 children diagnosed with autism
The purpose of this multi‐site intervention study was to examine the effectiveness of the iLs Focus home program with 18 children 4 to 8 years of age with Autism Spectrum Disorder (ASD). Results found significant gains across multiple subjective and objective outcome measures in areas of social skills and emotional regulation, number and severity of autistic behaviors, and overall functional adaptive behavior skills.

Auditory Processing Disorder (Download as PDF) iLs PDF Document

Julia Harper, PhD, OTR/L and Aimee Levine Weiner, Aud; published in Advance OT Magazine
Abstract: Therapeeds, a private clinic in Ft. Lauderdale, Florida, reports the results of 29 children diagnosed with APD who completed the Therapeeds’ H.O.P.E. sensory motor program combined with iLs. Among the pre- and post-program tests are the following:
Vestibular: Pre-testing indicated 0 of the 29 children had intact vestibular processing skills measured by the PrN and functional skills. Post-testing showed all 29 in normal range.
All Auditory Processing Skills: Post-intervention, 22 of the 29 children had auditory processing skills that were completely within normal limits in every area.
Medications: Seven of 29 children began this therapy on medication for attention-related concerns. By the end of the program, the medications for all 7 had all been discontinued.
ABR Binaural Summation: Pre-intervention ABR tests showed all 29 children had little difference between listening with one ear and listening with both ears (binaural summation). Post-intervention, all 29 tested in the normal range.

Denver Area Schools
Abstract: A variety of normed, standardized tests were used to assess 20 children with learning difficulties before and after iLs programs. The report includes each child’s pre- and post-program test scores as well as teacher and parent comments. Teachers involved in the program reported “significant improvement” in 19 of the 20 children. The criteria for “significant improvement” includes at least one of the following: being transitioned from special education to regular education, having an IEP removed or overcoming a substantial behavioral challenge. escription: Data on the efficacy of iLs in school programs.
