Let’s talk about one of the most exciting tools in chiropractic care: HRV (Heart Rate Variability). The nervous system is the control center of everything the body does—stress, recovery, performance, you name it. But here’s the kicker: most patients have no idea how their nervous system is doing until something goes wrong.

That’s why HRV matters. It’s like a spotlight on nervous system health. It shows how well the body handles stress and bounces back. With tools like CLA’s neuroPULSE, you can make the invisible visible. It’s not just about helping patients feel better—it’s about showing them how their nervous system is performing.

Let’s break it down. What is HRV, why is it perfect for chiropractic care, and how can you use it to build a practice patients trust and stick with?

What is HRV, and Why Does It Matter?

Heart Rate Variability measures the changes in the time between heartbeats. These tiny variations are controlled by the autonomic nervous system (ANS), which balances the sympathetic (fight or flight) and parasympathetic (rest and recover) systems.

Think of HRV as a nervous system performance score:

For chiropractors, HRV is a powerful way to see what’s happening with a patient’s nervous system—and to show them why care is needed.

Why HRV Fits Perfectly in Chiropractic

Chiropractic is all about the nervous system. That’s where everything starts and ends. But how do you show patients what’s happening when stress builds up or when a subluxation is causing nerve interference?

HRV scans are your answer. With tools like the neuroPULSE, you get real data on how the nervous system is managing stress and recovery.

Here’s what HRV helps you do:

When patients see their HRV improve, they understand that chiropractic isn’t just about fixing what’s wrong—it’s about building resilience for the future.

How HRV Scans Work

An HRV scan is simple, fast, and completely non-invasive. Using CLA’s neuroPULSE, you record heart rate variability and analyze how well the nervous system is balancing stress and recovery.

Here’s the process:

  1. The patient puts their hand into the neuroPULSE with the tips of their fingers under the main sensor. If the scan is being performed on a child, they can wear a small sensor clip during the scan instead.
  2. The system tracks heart rate variability in real time.
  3. The data shows whether their nervous system is thriving or struggling, displayed in a report with what we call the “Rainbow Graph”, a visual and easy-to-understand chart that plots where on a spectrum the patient’s nervous system stress is.

The best part? Patients can see the results for themselves. It’s no longer a mystery what’s happening inside their body—they can see the impact of stress and how chiropractic is making a difference.

HRV and Adaptability: Why It Matters

Here’s the big picture. HRV isn’t just about heartbeats, it’s about how well the nervous system adapts to life’s challenges.

When HRV is low, it’s a sign that the body is stuck in survival mode. This can lead to:

Chiropractic adjustments help reset the nervous system, improving HRV and building adaptability. This is where you go beyond symptom relief and focus on long-term health.

HRV and the CORESCORE™: The Full Picture

HRV is just one piece of the puzzle. When paired with neuroCORE (sEMG) and neuroTHERMAL, it becomes part of a bigger story about nervous system health.

The CORESCORE™ combines these three scans into one number that shows the full picture of a patient’s neurological function:

This combination lets you show patients exactly how their nervous system is responding to care. The CORESCORE™ simplifies the data into something they can see and understand, keeping them engaged and motivated.

How HRV Scans Boost Retention

Retention comes down to one thing: trust. Patients need to see that their care is making a difference. HRV scans provide that proof.

Here’s why HRV helps you keep patients:

Retention isn’t just about getting patients to come back. It’s about helping them see the value of consistent care for their nervous system.

With HRV, you’re not just adjusting spines—you’re helping patients see the connection between care and health in a way they can’t ignore.

FAQs About HRV in Chiropractic

What does HRV measure?
HRV measures the time between heartbeats to assess how well the nervous system is adapting to stress and recovery.

How often should HRV scans be done?
HRV scans are most effective when used regularly, such as during follow-up visits or progress checks, to track changes over time.

Are HRV scans safe?
Yes. HRV scans are completely safe and non-invasive.

Can chiropractic care improve HRV?
Yes. Chiropractic adjustments help reduce nerve interference, improving nervous system adaptability and increasing HRV.
