Brief Pain Inventory BPI short form [ Time Frame: Baseline through 4 weeks post baseline ] The BPI is a 9-item questionnaire that assesses severity of pain, impact of pain on daily function, location of pain, pain medications and amount of pain relief in the past 24 hours or the past week. Patient Health Questionnaire [ Time Frame: Baseline through 4 weeks post baseline ] The PHQ-9 is a 9-item reliable, valid, measure that rates depression symptom severity on a 4-point scale.

This study examines the impact of an innovative audiovisual stimulation AVS program on human brainwaves, and its usefulness to improve sleep. The AVS intervention, if demonstrated to be efficacious for sleep promotion, could benefit millions of people worldwide. Detailed Description:. Common comorbidities associated with OA include poor sleep, pain, depression, and fatigue. OA patients with insomnia tend to report greater pain than those without insomnia. A recent systematic review concluded that sleep disturbance is a stronger predictor of chronic pain than vice versa.

Prescription medication has good short term efficacy but benefits do not persist after treatment discontinuation and there are notable side effects. Treatment effects for CBT-I are comparable to or exceed those for medications, and have been shown efficacious for persons with OA pain. However, CBT-I practitioners are not yet available in many healthcare systems.

New, effective, and easy-to-use self-management alternatives could greatly help reduce the burden of insomnia and potentially decrease pain, depression, and fatigue in individuals with OA. We propose to test a novel, easily-used, self-management intervention to improve OA-related insomnia, pain, depression and fatigue: open-loop neurofeedback Audio Visual Stimulation AVS. AVS uses preprogrammed light and sound patterns to evoke brainwave potentials at pre-set deated Need visual stimulation. The AVS intervention consists of 30 minutes of light and sound pulsing stimuli that gradually descend from alpha 10 Hz to delta 2 Hz frequencies.

AVS placebo consists of 30 minutes of constant dim light slowly changing in color, and a steady monotone at ultra-low frequency below 1 Hz. This proposed Need visual stimulation builds upon our successful completion of three pilot studies using AVS. Based on the pilot findings, we hypothesize that the use of active AVS at bedtime induces delta brainwaves, but additional testing is needed to determine how long AVS should be used to produce ificant improvements in subjective sleep quality relative to placebo control.

In addition, we propose to experimentally test the effect of blue light, which is known to suppress melatonin production, as a potential confounding variable in the AVS intervention. We propose a trial of AVS in 75 community dwelling older adults with chronic comorbid insomnia and OA pain. Participants will self-administer AVS at bedtime nightly for one month.

Insomnia severity will be similarly assessed to determine the most efficacious AVS treatment duration and color array for improving insomnia symptoms. OA-related symptoms pain, depression, and fatigue and objective sleep outcomes will also be assessed. FDA Resources. Arms and Interventions. Active AVS-2 consists of a minute pulsing lights red, green and sounds that gradually descend from alpha 10 Hz to delta 2 Hz. Outcome Measures.

Primary Outcome Measures : Insomnia of Severity Index [ Time Frame: Baseline through 4 weeks post baseline ] A 7-item questionnaire that is a global measure of perceived insomnia severity. Cortical activity will be evaluated using a channel quantitative electroencephalographic system Discovery 24E, BrainMaster with a standard electrode cap that has 22 sensors attaching to the scalp.

Self-rating of overall sleep quality and disturbances using 7 sleep components. The BPI is a 9-item questionnaire that assesses severity of pain, impact of pain on daily function, location of pain, pain medications and amount of pain relief in the past 24 hours or the past week. The PHQ-9 is a 9-item reliable, valid, measure that rates depression symptom Need visual stimulation on a 4-point scale.
