A Pilot Study of Audio–Visual Stimulation as a Self-Care Treatment for Insomnia in Adults with Insomnia and Chronic Pain

摘要: This pilot study tested the efficacy of an audio–visual stimulation (AVS) program for promotion sleep in individuals with chronic pain. Insomnia and pain are common comorbid conditions their relationship has been viewed as bidirectional. Recent studies suggest a relatively dominant role this dyad. The premise was that AVS enhances low frequency while reducing high brain activity resulting decreased hyperarousal improved potential consequent reduction We conducted intervention using pre–post design. Participants self-administered 30-min nightly at bedtime 1 month. Sleep were assessed baseline conclusion 4-week phase. Nine adults (mean age 33 ± 15.8 years; female, 89 %) completed study. After device 4 weeks, significant improvement seen reported insomnia (ISI, p = 0.003), severity (BPI, 0.005), interference functioning 0.001). Large effect sizes (Partial η2 0.20–0.94) (Cohen’s d 0.44–1.45) observed. results may be efficacious decreasing both symptoms. In order to better assess possible reduction, more definitive randomized controlled trials will needed. These should include appropriate sample sizes, objective measures pain, longitudinal follow-up.
