Before your baby's first adjustment, our doctors run a scan. It takes a couple of minutes, involves no needles and no discomfort, and it is easy to nod along without fully understanding what it is measuring or why it matters. If you have wondered what that scan actually shows, or what a follow-up scan looks like once your baby has been in care for a few weeks, here is the plain-language version.
What the Scan Is Actually Measuring
INSiGHT scanning does not look at bones or joints the way an X-ray would. It measures how your baby's nervous system is functioning right now, in real time. A thermal scan run along either side of the spine picks up small temperature differences that show where the autonomic nervous system, the part that runs digestion, heart rate, and the shift between stress and calm, is working evenly and where it is not. A surface EMG reading measures muscle tension held along the spine, which tends to build up wherever a baby's nervous system has been working overtime to manage stress. Heart rate variability adds a third piece, showing how well your baby's system is able to shift between alert and calm states rather than getting stuck in one.
Put together, these three readings give our doctors an actual picture of where tension is being held in your baby's nervous system, rather than a guess based on symptoms alone. For a colicky baby, this usually means looking closely at the upper neck and mid back, where the vagus nerve and the nerves reaching the stomach and intestines travel.
What the Colors Mean
The scan output shows up as a color-coded map running down either side of the spine. Cooler, more even colors generally reflect a nervous system that is regulating well in that area. Areas that show up hot, or with a lot of green, blue, or red clustered together, tend to point to spots where nervous system tension has built up and is not resolving on its own. For a baby with colic, it is common to see that pattern concentrated right at the base of the skull and upper neck, exactly where the vagus nerve begins its path down toward the digestive organs.
None of this is meant to alarm you. Newborns go through real physical stress during birth, even in births that look completely uneventful from the outside, and some tension in this area is common. What the scan does is turn a pattern that would otherwise be invisible into something specific enough to work with.
Why a Picture Matters More Than a Guess
Colic gets talked about as one thing, but the crying, the gas, the arching, and the trouble settling can come from slightly different places in different babies. Two babies who look the same from the outside, both crying for hours every evening, can show very different scan patterns underneath. One might show tension concentrated in the upper neck, pointing toward vagus nerve involvement in digestion and settling. Another might show a broader pattern that also touches the mid back, where nerves reaching the stomach and intestines travel.
Rather than treating every colicky baby the same way, the scan lets our doctors see where your baby's particular pattern sits and build the care plan around that, using Koren Specific Technique and Talsky Tonal Chiropractic to work specifically where the readings point.
What a Rescan Looks Like
Our doctors typically bring your baby back in for a follow-up scan every few weeks of care, not because the first scan was wrong, but because a single scan is only a snapshot. What matters more is the direction things move over time.
A rescan that is trending in the right direction usually shows a few things: the hot, clustered coloring in the upper neck and mid back starts to even out and cool down, the muscle tension readings drop toward a calmer baseline, and heart rate variability starts to show more flexibility between alert and calm states instead of staying locked in one. None of this happens instantly. Some babies show a shift within the first couple of visits, and others take longer, particularly if the birth involved more physical stress or if colic is showing up alongside reflux or constipation.
What Parents Can Actually Watch For
- Less crying overall, and crying episodes that end sooner once they start
- An easier latch and calmer feeding sessions
- Less visible gas, bloating, and spitting up
- More regular bowel movements
- Longer, steadier stretches of sleep
These everyday changes usually show up around the same time the scan pattern starts to even out, which is why our doctors watch both side by side rather than relying on either one alone.
Where This Fits Into Your Baby's Visit
The scan is not a pass or fail test, and it is not the only thing that shapes your baby's care. It is one more piece of information, alongside the birth story you share and what our doctors find during a hands-on exam, that helps build a plan specific to your baby rather than a generic one. Many parents find it reassuring to have something concrete to look at, rather than only going off how the last few nights went.
