FieldCheck walks through mechanism, exam findings, and differential diagnosis the way a sports medicine clinician does. Pick a region to begin — each module is a self-contained trainer.

Training tool only. Not a substitute for evaluation by a physician, athletic trainer, or other licensed provider. Always seek professional care for real injuries.
FieldCheck · v0.6
Step 1 of 6 · Athlete
Age and sport shape the diagnosis.
Skeletally immature athletes have entirely different pathologies that overlap clinically with adult conditions but live in a different diagnostic neighborhood.
Step 2 of 6 · Pain Location
Where exactly does it hurt?
Location alone narrows the differential dramatically.
Step 3 of 6 · How it happened
What was the mechanism?
Mechanism + location = the most powerful predictor of which structure is involved. Select every mechanism that applies — real injuries are often compound.
Step 4 of 6 · Red Flags
Red flag screening.
Validated decision rules and can't-miss findings that change the disposition immediately.
Step 5 of 6 · Symptoms
The diagnostic trio.
Pain, swelling, function. Time since injury matters — acute vs. chronic changes the whole differential.

Step 6 of 6 · Clinical Exam
Which tests are positive?
Tap any test that reproduces pain, instability, or a positive sign. Tap again to toggle off. Tests stress specific structures — that's how the differential narrows.
