How We Scan the Nervous System (and Why It Matters)

There's a Reason You're Still Searching for Answers.

You've tried the diets. The supplements. The sleep training, the therapies, the meds. Maybe things got a little better—or maybe nothing worked at all.

What if the root cause isn’t in the gut, or the behavior, or the immune system?

What if the issue is deeper—in the control center of the body itself: the nervous system?

At Three Nails Chiropractic, the first thing we do is look where no one else has looked—and we use advanced technology to do it.

Why the Nervous System Matters

Your nervous system controls everything—movement, digestion, emotions, focus, sleep, immune response… literally every function in the body.

When the nervous system is stressed or out of balance, it throws everything else off too. But here's the challenge: nervous system dysfunction is invisible on blood tests, MRIs, or even most physical exams.

That’s where our INSiGHT Scans come in.

What Are INSiGHT Scans?

INSiGHT Scans are a suite of non-invasive, painless tools that allow us to measure exactly how your nervous system is functioning. No guesswork. No "wait and see." Just real data.

We use three types of scans to get a full picture of how your body is functioning:

1. Heart Rate Variability (HRV)

Measures how your body is handling stress and recovering from it. Low variability = stuck in fight or flight. High variability = healthy adaptability.

2. Thermography

Detects temperature imbalances along the spine, revealing areas of tension and dysfunction in the autonomic nervous system (think digestion, immune function, hormones, sleep).

3. Surface EMG

Measures the energy and tone in the muscles along the spine—especially important for kids with ADHD, sensory issues, sleep struggles, or emotional dysregulation. It tells us if the brain is "stuck on the gas pedal."

📊 These scans give us a digital fingerprint of your stress patterns—and help us track how they change over time with care.

Why This Matters for Your Child

So many kids we see are stuck in sympathetic overdrive—their bodies are constantly on alert. This can show up as:

• Anxiety

• ADHD

• Sleep problems

• Chronic constipation

• Immune struggles

• Emotional outbursts

• Sensory meltdowns

• Speech or developmental delays

Most of the time, families are told they’ll “grow out of it” or are offered a medication to manage symptoms.

But we’re not interested in just managing symptoms.

We’re here to find the root cause—and help your child’s nervous system finally shift into healing mode.

How We Use These Scans to Help You Heal

Once we’ve completed the scans, we:

• Walk you through a full, clear explanation of the results

• Show you how the patterns of stress have developed over time

• Create a customized care plan based on your unique scan findings

• Track progress with follow-up scans every 12 visits to make sure we’re on the right track

Parents often say the scan results give them the first real answers they’ve gotten. Many even get emotional seeing how much stress their child has been carrying—without anyone noticing.
