Clinical Trial Summary

Background and Purpose: The purpose of the study is to test the efficacy of an audio-visual stimulation program for sleep promotion in adults with chronic pain. The hypothesis is that hyper-arousal plays an important role in insomnia. Brainwave entrainment from 8 to 1 Hz reduces arousal, and thereby improves sleep. Improved sleep may change how people perceive pain.

Methods: Using a double-blind, randomized controlled trial design, we plan to enroll 30 adults (21-65 years old) experiencing both nonmalignant pain and insomnia. Exclusion criteria include: seizure disorder, sleep disorder, and night shift workers. After a one-week baseline measure, participants will be randomized to intervention or placebo group. Participants in both groups will be asked to self-administer the audio-visual stimulation program every night at bedtime for one month. Upon completion, post intervention measures will be collected.


Clinical Trial Description

Background: The purpose of this pilot study was to test the efficacy of an open-looped Audio-visual Stimulation program (AVS) for sleep promotion in older adults with osteoarthritis pain. In this study, the AVS program was tested in a randomized controlled design. Specifically, this pilot study examined a 30-minute audio-visual stimulation program that gradually ramped from 10 Hz down to 2 Hz, to be used at bedtime for delta brainwave induction, in a randomized controlled design. The placebo control AVS program consisted of 30-minutes of constant dim light that slowly changed in color, and a steady monotone at ultra-low (<1 Hz) frequency (outside of the entrainment range).

Method: A total of 30 older adults (mean age 68 ± 5.1, 90% women) with comorbid insomnia and osteoarthritis pain participated in this 2-week study. Participants were randomly assigned to either AVS active program or AVS placebo control program. After the baseline assessment (which included questionnaires [sleep, pain, depression], and quantitative electroencephalogram (QEEG) during AVS induction), participants were asked to self-administer their group specific AVS program nightly at bedtime for two weeks. Post-treatment questionnaires (sleep, pain, depression) were then collected. ;
