Study type | Interventional |
This randomized, controlled clinical pilot trial will evaluate the effects associated with in-office use of closed-loop, acoustic stimulation neurotechnology (High-resolution, relational, resonance-based, electroencephalic mirroring; HIRREM), compared with acoustic stimulation not linked to brainwaves (ambient nature sounds), for participants with pre-hypertension. Data collection will occur at baseline, and at intervals after completion of the intervention. Outcomes include blood pressure, measures of autonomic cardiovascular regulation, behavioral symptom outcomes, quality of life, alcohol use, and functional performance measures. The primary outcome will be change in blood pressure from baseline to 4-6 weeks after intervention.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Blood Pressure | Change in systolic and diastolic blood pressure | Data used for analysis of primary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | Insomnia Severity Index (ISI) | The severity of insomnia symptoms is measured using the ISI with each data collection visit. The ISI is a 7 question measure, with responses from 0-4 for each question, yielding scores ranging from 0-28. | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | Pittsburgh Sleep Quality Index (PSQI) | The PSQI is a 19 item inventory that assesses sleep quality over a 1-month time interval. Items are weighted on a 0-3 interval scale. A global PSQI score is calculated by totaling the seven component scores, providing an overall score ranging from 0 to 21, where lower scores denote a healthier sleep quality. | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | Epworth Sleepiness Score (ESS) | The ESS measures a person's general level of daytime sleepiness, or their average sleep propensity in daily life. The simple questionnaire is based on retrospective reports of the likelihood of dozing off or falling asleep in a variety of different situations. Rated on a 4-point scale (0-3), it evaluates their usual chances of dozing off or falling asleep while engaged in eight different activities. The ESS score (the sum of 8 item scores, 0-3) can range from 0 to 24. | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | Center for Epidemiologic Studies Depression Scale (CES-D) | The Center for Epidemiologic Studies Depression Scale (CES-D) is a depression scale which will help to assess this co-morbidity. CES-D is a 20-item survey assessing affective depressive symptomatology to screen for risk of depression. Scores range from 0-60, with a score of 16 commonly used as a clinically relevant cut-off. | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | Generalized Anxiety Disorder-7 (GAD-7) | The Generalized Anxiety Disorder-7 (GAD-7) is a seven item screening tool for anxiety that is widely used in primary care. GAD-7 is a brief, reliable and valid measure of assessing generalized anxiety disorder. | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | PTSD Checklist for Civilians (PCL-C) | The PTSD Checklist for civilians (PCL-C), measures the American Psychiatric Association's Diagnostic and statistical manual of mental disorders (DSM-IV) Criteria B, C, & D of PTSD symptoms based on traumatic life experience related to military service. Seventeen items are rated on a Likert scale with a composite score range of 17 to 85. A score of 44 or higher correlates with probability of civilian-related PTSD. | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | Perceived Stress Scale (PSS) | The Perceived Stress Scale (PSS) is a ten-item psychological instrument for measuring the perception of stress. It is a measure of the degree to which situations in one's life are appraised as stressful. Items were designed to tap how unpredictable, uncontrollable, and overloaded respondents find their lives. The scale, with answers rated from 0-4, also includes a number of direct queries about current levels of experienced stress. | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | Quality of Life Scale (QOLS) | The Quality of Life Scale (QOLS) is a 16-item scale that was modified from a 15-item scale used in chronic disease patients. Topics include different components of daily life such as relationships, community engagement, personal fulfillment, and recreation. Each item is scaled from 1 to 7 and a sum score is calculated to represent higher levels of satisfaction in life (range is 16-112). | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | AUDIT-C | The AUDIT-C is a short, 3-item alcohol screening for hazardous drinkers or active alcohol use disorders. This measure consists of 3 questions to assess an individual's alcohol use. Each question has five possible answers ranging from of 0-4 with a total scoring scale of 0-12. A total score of 3 or more in women and a score of four or more in men is suggestive of hazardous drinking or active alcohol use disorders. This form is modified from the longer, 10-item AUDIT instrument. | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | Reaction Testing | Reaction testing will be evaluated by a drop-stick, clinical reaction time apparatus. It is constructed from a meter stick covered in friction tape with gradations. The modified meter stick is fixed to a weighted rubber cylinder. The apparatus is placed between the thumb and index finger of the subject and released at a random time during a countdown. The subject catches the apparatus and the distance fallen (cm) is converted to reaction. Following two practice trials, subjects perform eight trials, and a mean distance value is used for analysis. This is repeated with a second set of 8 trials later during the enrollment visit, and the mean distance value from the second trial will be used as the baseline value. Use of the average distance from the second set of trials will be used as the baseline value so as to avoid the impact of learning effect for this test. | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention | |
Secondary | Grip Strength | Grip strength will be evaluated using a hydraulic hand dynamometer (Baseline Hydraulic Hand Dynamometer). The greatest force generated during three trials will be used for analysis. | Data used for analysis of secondary outcome is collected at the enrollment visit, 1-7 days after the intervention is completed, 4-6 weeks after the intervention is completed, and 12-14 weeks after completion of the intervention |
