Kynexis Movement Recognition Index

The Early Warning System
for Athletic Movement.

Injuries don’t show up on game day — they’ve been drilling in practice for weeks. Kynexis MRI catches the pattern in the reps, before it costs you the game.

The reps catch it early.

You’ve got choices — pitch counts, velocity trackers, recovery apps. Good tools, all of them. But none of them tell you what’s actually happening underneath: whether your athlete’s movement is quietly building toward an injury. Kynexis MRI does one thing — score that risk, clearly and objectively, in minutes — backed by 11+ years of UCL research and 500+ elbow evaluations. Not a replacement for your program. The missing piece in it.

THE UNCOMFORTABLE TRUTH

You can hear the engine. You can’t see the timing belt.

Watching a pitcher throw and judging whether their mechanics are safe is a little like listening to an engine and guessing whether the timing belt is about to go. A good ear might catch something’s off. It won’t tell you which part, how close it is to failing, or how many more starts it has left in it.

That’s the position most coaches, parents, and even athletes are in every single game day. They can see the fastball. They can hear the pain, once it shows up. What they can’t see is the quiet, technical layer underneath.

The arm wasn’t hiding anything. It was speaking a language nobody in the dugout had been taught to read.

A hip that rotates a few degrees shortBarely visible. Compounds every rep.

A scapula that fires a beat lateNo pain yet. Just a pattern building.

A lunge that leaks force instead of storing itEnergy that should load the throw goes somewhere else.

Season after season, the pattern repeatsShut down. MRI. Diagnosis. Everyone acts surprised — the arm wasn’t.

You don’t need to learn biomechanics to close the gap.

You just need a tool that already has. Kynexis MRI runs five simple movement screens and turns them into one plain-language risk score, backed by 11+ years of UCL research and 500+ elbow evaluations. No jargon. No guesswork. Just an early, honest answer — in time to act on it.

WHAT KYNEXIS MRI MEASURES

Five screens. One number… that tells the truth.

Chosen to expose the specific movement faults linked to throwing-injury risk — scored individually, and rolled into one composite index.

/ 40

Composite Score

01 · SPINE

Thoracic Rotation

Upper-spine rotation to load and release energy

02 · SHOULDER

Scapular Mobility

Shoulder blade moving through its full, stable range

03 · LOWER BODY

Lateral Lunge

Storing and transferring force side-to-side

04 · BALANCE

Single-Leg Mini Squat

Single-leg stability and control under load

05 · HIP

Internal Hip Rotation

Hip mobility that feeds directly into arm timing and stress

MRI Score

24/40

A Single, Clear Risk Score

Five results synthesized into one composite score (e.g., 17/40) — an at-a-glance read on overall injury risk, built on the same framework behind 11+ years of longitudinal UCL research.

Progress Tracking Over Time

Athletes get re-tested, and the app tracks scores across sessions — so you’re seeing whether risk is trending down, or creeping up, as training progresses.

Test-to-Test Comparison Reports

Generate reports comparing one assessment directly against a prior one — showing exactly which patterns improved, which didn’t, and where residual risk still sits.

Plain-Language Narrative Reports

Every assessment generates a report written for coaches, parents, and athletes — not clinicians. No jargon to decode, no chart to interpret alone.

Guided Onboarding

A full onboarding video series walks new users through running each test correctly, plus a companion instructional guide — so results stay consistent no matter who’s administering it.

Field-Ready, No Special Equipment

Screens run in minutes, on-site — no lab, no imaging, no specialized gear required.

SEE IT IN ACTION

What a real assessment looks like.

Actual screens from the Kynexis MRI app — from a single test, to a full player report, to a team-wide view.

Run a Screen

Each test — like Thoracic Rotation — is measured left and right, with specific movement faults flagged as they’re observed.

Get the Score

All five screens roll up into one Overall MRI Score, plus a ranked corrective exercise prescription for every flagged pattern.

See the Whole Roster

Team Reports roll every athlete’s screen into one view — so you know exactly where your team’s risk actually sits.

Track Every Athlete

Every player gets their own dated results, corrective drills, and a running record of what’s changed since the last screen.

Review the Rep

Video-backed measurements for every test — so a score is never just a number, it’s tied to the actual movement.

FROM THE FIELD

Built on decades of catching what the eye can’t.

“I’ve sent my athletes to Chuck for years and highly recommend his transcendent approach to athletic elbow care.”

Youth & Travel Baseball CoachClient of Human Motion Associates

“When I developed elbow pain in high school, my coach sent me to Chuck, who quickly suspected a serious issue and referred me to a top orthopedic surgeon. After my diagnosis, Chuck’s gait and motion analysis revealed limited hip mobility and flawed mechanics, including an overly long stride that stressed my elbow. With his guidance, I rehabbed, improved my mechanics, and now throw more efficiently with greater command and velocity while reducing stress on my arm.”

Former High School PitcherClient of Human Motion Associates

Not just for baseball and softball.

The five screens inside Kynexis MRI are universal to any sport, or any activity of daily living. Coaches across other sports — and trainers working outside of throwing athletes altogether — use the same movement-quality framework to spot limitations before they become compensations.
