简要总结
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.
详细描述
This will be a randomized, single site, controlled, pilot clinical trial, to evaluate the effects of in-office use of a closed-loop, allostatic, acoustic stimulation neurotechnology (High-resolution, relational, resonance-based, electroencephalic mirroring; HIRREM), compared with acoustic stimulation not linked to brainwaves (ambient nature sounds). Assuming a potential drop-out rate of 20%, up to 24 subjects will be enrolled to achieve a goal of having at least 20 subjects (10 per group) complete the study, per protocol. Patients who have blood pressures between 120-139 mm/Hg systolic, and/or 80-89 mm/Hg diastolic, as documented by their health care providers on two separate occasions, and no other exclusions, will be randomly assigned to receive either 8-16 sessions of either acoustic stimulation linked to brainwave activity (HCC), or acoustic stimulation not linked to brainwave activity (NCC), over a maximum of 4 weeks, with both groups continuing their current care throughout. There will be pre- and post-intervention data collection to include systolic and diastolic BP, and many secondary outcome measures including measures of autonomic cardiovascular regulation (continuous recording of BP and HR for calculation of measure of HRV and BRS), behavioral symptom outcomes (ISI, PSQI, ESS, CES-D, GAD-7, PCL-C, PSS), quality of life measure (QOLS), alcohol use (Audit C), and function performance measures (drop stick reaction testing, and grip strength). All measures will be collected at an enrollment visit (V1), and the intervention will begin 1-14 days later. BP and HR recordings will also be repeated prior to the start of the 7th session. Post-intervention data collections will be obtained at 1-7 days (V2), 4-6 weeks (V3, primary outcome), and 12-14 weeks (V4) following completion of the intervention. The primary outcome will be differential change in the systolic and diastolic BP from V1 to V3. Additional follow up (V4) will evaluate durability of effects. Following V4, those in the NCC group will be offered the opportunity to cross over to receive a course of HCC, and will continue to be followed for data collections at 1-7 days (V5), 4-6 weeks (V6), and 12-14 weeks (V7) after completing their crossover HCC sessions. Linear mixed models (LMMs) will be used to contrast longitudinal changes in systolic and diastolic blood pressure between the HCC and NCC groups. Mean contrasts will be used to compare the changes in blood pressures between groups from V1 to V3, our primary test of efficacy. Additional mean contrasts will be constructed to evaluate the consistency of any benefit of HIRREM through subsequent visits beyond V3. Comparisons of changes in all secondary outcomes will be assessed in a similar fashion.
