Validating Brain Performance with HQP and Brain Gauge: A New Frontier for NeuroVIZR
Contributor: Dr. Michael Kessler, DC – Co-Founder, HeartQuest Global, LLC
At HeartQuest Global in Arizona, we specialize in helping practitioners measure what matters—using objective, science-backed tools to validate the effects of health technologies and treatments. One of our key platforms, HeartQuest Professional (HQP), is a 5-minute biofeedback system that gives a window into nervous system function, hormonal balance, mitochondrial health, and even traditional meridian systems.
Recently, we’ve been working to integrate HQP with the NeuroVIZR, combining our data-driven insight with brain-based stimulation. The goal? To quantify how NeuroVIZR impacts the brain and nervous system—and to help practitioners see exactly how their sessions are working.
Why HRV Matters for Validation
Heart Rate Variability (HRV) reflects the balance between the stress (sympathetic) and recovery (parasympathetic) branches of the autonomic nervous system. Think of it as a measure of how well the body adapts to stress—and it’s one of the most widely recognized biomarkers for nervous system health, resilience, and emotional regulation.
While most consumer devices give basic HRV data, HQP goes deeper with:
- 1,000 Hz sampling (vs. 250–500 Hz in standard systems)
- Multi-dimensional insights (neuroendocrine, meridians, biorhythms, and more)
- Real-time recommendations, including NeuroVIZR session suggestions
- Bioenergetic feedback, connecting HRV to energetic patterns seen in TCM and Ayurveda
Importantly, HQP captures the Very Low Frequency (VLF) range—an often-overlooked signal linked to chronic stress and brainstem activity. Many wearables miss this entirely.
Key HRV Indicators We Track
As we begin applying NeuroVIZR protocols, we monitor changes in core HRV markers:
- LF (Low Frequency): Stress/adrenal response
- HF (High Frequency): Rest, recovery, and vagal tone
- VLF (Very Low Frequency): Brainstem and CNS regulation
- Total Power: Overall autonomic energy and vitality
-
Stress Index: Sympathetic dominance and fight-or-flight activation
We'll be sharing real-world case examples in upcoming newsletters—showing how NeuroVIZR improves these indicators in areas like memory and cognition.
Adding Brain Gauge: A Visual for Brain Recovery
To further enhance our validation tools, we've integrated Brain Gauge, a cutting-edge neurosensory assessment platform that evaluates cognitive speed, accuracy, plasticity, and more.
Think of Brain Gauge like an eye exam for your brain. It uses precise fingertip response tasks to assess how well different brain networks communicate. As NeuroVIZR sessions progress, we can visually track improvements on a radar screen—highlighting gains in:
- Speed – Sensory processing
- Accuracy – Judgment and response control
- Plasticity – Neuroplastic potential (a key target of NeuroVIZR)
- Time perception – Coordination and timing
- Fatigue – Neural endurance
- Focus – Sustained attention
- Overall cognitive function
For example, in a recent case with a TBI (traumatic brain injury) patient, we saw a clear visual improvement in radar plot scores after a series of neuroVIZR sessions.
Why This Matters
Together, HQP and Brain Gauge allow us to objectively measure how the brain and body respond to NeuroVIZR—validating what clients are feeling with real data. Whether it's boosting parasympathetic tone, restoring attention, or improving neurological fatigue, this integrated approach is helping practitioners personalize treatment, track progress, and accelerate recovery.
We’re excited to continue sharing results and insights from our ongoing research—and we welcome any NeuroVIZR partners who want to explore these tools in their own practices.
