A start-to-finish walkthrough of the platform, the science behind every number, and exactly how to run a scan. Built so anyone on your team can do it — no clinical background required.
Use ← → arrow keys, or the buttons at the bottom, to move through the slides.
Front desk, MA, nurse, provider — anyone can run a RootSignal™ scan. You do not need to be clinical. If you can follow a recipe, you can run RS.
We define every term from scratch. Nothing is assumed.
RootSignal™ turns a 2-minute scan and a short symptom form into one simple, branded health score — the Vitality Index — plus a map of where a patient's body is under strain. A $199 saliva panel then completes the score.
One 0–100 score that says, in plain terms, "how well is my body actually running?"
7 body systems, each shown Low / Moderate / High — so care is targeted, not guesswork.
The first score is deliberately incomplete. The saliva panel closes the loop — and that drives the visit and the care plan.
Every clinic runs the exact same 8 steps. The rest of this deck teaches each one.
Parts 2 explains the science. Part 3 shows you the clicks.
LIFE = Longevity Internal Function Evaluation. It's the short form the patient fills out before the visit, on their phone. It has three parts.
7 short sections about how they've been feeling. (Detailed in the next slides.)
A checklist of major life changes — the stress the body has been carrying.
A short privacy consent so you can use their answers to prepare their results.
The LIFE form isn't a random survey. Each part is built on an established, published instrument — so it stands up to scrutiny.
Stress/HPA is weighted heaviest because the scan directly measures it — so it carries the most signal.
Each event carries a Life Change Unit (LCU) value from the original 1967 research, ranked by how much readjustment it demands. The patient's total is the sum of what they checked.
Notice even "good" events (marriage, vacation) count — because the body still has to adapt.
A small sensor reads the patient's pulse — on a finger, ear, or wrist; wired or Bluetooth. RootSignal™ measures the tiny gaps between heartbeats and reads a lot from them. The next slides define each number the scan produces.
Every one of these comes from the same thing: the inter-beat interval — the time (in milliseconds) from one heartbeat to the next.
A car's suspension. A stiff, rigid ride (low HRV) feels every bump. A responsive suspension (high HRV) absorbs the road. HRV is your nervous system's suspension.
RootSignal™ reports HRV two ways — RMSSD and SDNN — on the next two slides.
Higher is better. Measured in milliseconds (ms).
RMSSD = the root mean square of successive differences — take the gap change between each pair of beats, square it, average it, square-root it. It highlights the fast, breath-driven wiggle that the vagus nerve controls.
SDNN = the standard deviation of all the inter-beat intervals — how widely the beat-to-beat timing spreads out over the recording. A tiny spread means a rigid, "flat" heart rhythm; a healthy spread means a responsive one.
Higher is better. It rises when someone breathes slowly (~6 breaths/min).
Rhythm was smooth and ordered — the target state. More time here is better.
On the way to coherent — partially in sync.
Jagged, stress-pattern rhythm — not yet coherent.
This is called respiratory sinus arrhythmia (RSA) — the natural heart-rate rise/fall with each breath. RootSignal™ finds that oscillation in the heart-rhythm signal and converts its frequency to breaths per minute.
One glance = "how am I doing?" The systems map tells them why.
The scan + form give a real score — but it's deliberately incomplete without the hormone panel. So RootSignal™ shows it as Preliminary and holds it back by ~10%. It's an honest "we're not done yet."
The picture is missing the objective hormone data, so we present the score conservatively — under-, never over-stated.
The real lab values resolve the score to its true number. It usually rises — but will drop if the labs reveal a real driver. That honesty is the point.
The daily pattern matters as much as any single value — that's what saliva timing captures.
The next slides mirror exactly what's on your screen.
Pressing Next opens the Results Review deck — a guided, glowing-body walkthrough you present with the patient, system by system, ending on their report.
Right on the results, the patient chooses — and the system routes them automatically:
The complete Vitality Index + the systems map are the perfect springboard into your clinic's core program. RS did the hard part — it made the invisible visible and gave the patient a reason to go deeper.
Review the true number and what the labs revealed.
Point the plan at the highest-burden systems.
Re-scan later to show progress — this is what keeps patients.
| Metric | What it is (plain) | Better = | Bands |
|---|---|---|---|
| Vitality Index | Overall "how well the body runs," 0–100 | Higher ↑ | Preliminary until ASI, then Complete |
| System burden | Strain in one of the 7 systems, 0–100 | Lower ↓ | Low <45 · Moderate ≥45 · High ≥70 |
| Coherence | How smooth/ordered the heart rhythm is | Higher ↑ | Low <1 · Medium 1–1.9 · High ≥2 |
| Time in Coherence | % of the scan spent High/Med/Low | More High ↑ | watch the High % |
| HRV · RMSSD | Fast beat-to-beat flex (recovery system) | Higher ↑ | <20 Low · 20–39 Reduced · ≥40 Healthy (ms) |
| SDNN | Total variability across the read | Higher ↑ | ms — bigger spread = more adaptable |
| Respiration | Breaths per minute, read from the pulse | ~6/min for calm | slow & steady = coherent |
| Life Events (LCU) | Holmes-Rahe life-stress load | Lower ↓ | Low ≤149 · Moderate ≤299 · High 300+ |
Remember: a higher Vitality Index is better; a lower system burden is better.
That's the whole job — and now you know the science behind every step. This deck lives in your Provider Portal for whenever you need a refresher.
