INSiGHT scanning technology is a FDA-registered neurological assessment system used in chiropractic settings to objectively measure autonomic nervous system function, paraspinal muscle activity, and spinal thermal patterns. It provides quantitative data on nervous system health that does not rely on patient symptom reporting. At Myrtle Grove Chiropractic in Wilmington, NC, Dr. Margie uses INSiGHT scans as the primary intake and progress assessment tool — because if you cannot measure the nervous system, you cannot track whether care is actually working.

The Three Components of INSiGHT Scanning

1. Heart Rate Variability (HRV) — Autonomic Balance

The HRV component measures the autonomic nervous system's flexibility through analysis of beat-to-beat heart rate variation. The measurement takes approximately 3 minutes and produces a score that reflects the ratio of sympathetic to parasympathetic activity.

INSiGHT HRV analysis uses spectral frequency analysis to separate high-frequency (parasympathetic) and low-frequency (sympathetic) HRV components. This gives a more detailed autonomic picture than simple RMSSD HRV measurements used in wearable devices like Apple Watch or Garmin fitness trackers.

2. Surface Electromyography (sEMG) — Paraspinal Muscle Activity

The sEMG component measures the electrical activity of the paraspinal muscles on both sides of the spine simultaneously. Asymmetrical muscle activation patterns indicate segmental spinal dysfunction — areas where the joint is restricted and the nervous system has altered motor output to compensate.

The INSiGHT sEMG system reads 22 spinal levels from C1 to L5. Abnormal readings appear as colored indicators on a graphical spinal display that Dr. Margie reviews with patients during the report of findings visit. This makes abstract nerve function visible in a format that patients understand immediately.

3. Thermal Scan — Autonomic Nerve Function

The thermal scan component uses dual paraspinal temperature sensors to detect skin temperature differentials along the spine. These differentials reflect the activity of the autonomic nerves that regulate vasodilation and vasoconstriction in the skin's blood vessels. Asymmetrical thermal patterns indicate areas of autonomic nerve dysfunction.

The thermal component is particularly useful for identifying the cervical and thoracic levels where visceral organ innervation is being affected by spinal dysfunction — a clinical finding that connects back to the systemic symptoms (digestive, immune, cardiovascular) that many chiropractic patients present with beyond their primary musculoskeletal complaint.

What INSiGHT Scanning Shows That X-Ray and MRI Cannot

X-ray reveals bone position and disc space. MRI reveals soft tissue structure and disc pathology. Neither measures nerve function. A patient can have a structurally normal MRI and a profoundly dysregulated nervous system — a situation that explains why many MRI-cleared patients continue to experience symptoms that no structural explanation accounts for.

INSiGHT scanning fills this gap. It measures what the nervous system is doing, not just what the spine looks like. This distinction matters for:

• Patients with normal imaging but persistent symptoms

• Patients who want to understand the functional impact of their structural findings

• Patients tracking progress from a neurological (not just pain-based) perspective

• Children who cannot reliably self-report symptom changes

The Scoring System

INSiGHT uses a color-coded scoring system derived from population norms. Green indicates normal neurological function for age. Blue, yellow, and red indicate increasing degrees of dysfunction.

The composite score across all three measurements produces an overall neurological score, which Dr. Margie uses as the primary benchmark for tracking progress. A patient who starts at a score of 420 and improves to 680 over 12 weeks of care has objective evidence of neurological recovery — regardless of how their pain levels have fluctuated during that time.

INSiGHT Scanning in Wilmington, NC

Myrtle Grove Chiropractic is one of the few practices in the Wilmington area using INSiGHT technology as a routine intake and progress assessment tool. New patient evaluations include a full three-component INSiGHT scan, a report of findings that explains the results in plain language, and a care plan recommendation based on the scan data.

Frequently Asked Questions

What is INSiGHT scanning technology? INSiGHT is an FDA-registered neurological assessment system used in chiropractic care to measure autonomic nervous system balance, paraspinal muscle activity patterns, and spinal thermal (autonomic nerve) function through three integrated components: HRV analysis, surface electromyography, and thermal scanning.

Is INSiGHT scanning painful? No. All three INSiGHT scan components are completely non-invasive and painless. The HRV measurement uses sensor clips. The sEMG and thermal scan use surface probes that run along the spine without contact pressure.

How often are INSiGHT scans repeated? At Myrtle Grove Chiropractic, a baseline scan is performed at intake and progress scans are conducted at defined intervals based on the care plan — typically at 12, 24, and 36 visit benchmarks for active care patients.
