OMM

Start here. Core Tenets, TART criteria, structural exam, acute vs chronic SD, barriers, Fryette's Laws (all three), naming somatic dysfunction, and direct vs indirect treatment. The mental model every other OMM page assumes you have.

Deep dive on the coupling mechanics: neutral group vs single F/E segment, why sidebend and rotation go the same or opposite direction, and how to apply both laws when the question stem gives you a transverse process finding.

L-spine mechanics, Fryette's Laws at the lumbar level, Type I group vs Type II single-segment diagnosis, and why that distinction determines your treatment choice on the board.

Dextro vs levo naming, structural vs functional, rib humps, Fryette's Type I applied to the whole curve. Interactive spine + name-the-curve challenges + quiz.

C0-C7 mechanics. OA, AA, and typical cervical dysfunctions. Fryette's does NOT apply here. Rotation and sidebend couple the same direction at all cervical levels (that's the trap).

Anterior and posterior innominate rotation: ASIS, PSIS, leg length findings, and how each rotation pattern presents on the structural exam table.

Superior/inferior shears, in-flare vs out-flare, and how pelvic asymmetry patterns differentiate from rotations on clinical questions.

Tender point locations, 90-second hold, and the indirect logic behind counterstrain. Lumbar and pelvic points with positioning diagrams.

How organ pathology creates palpable somatic findings. The reflex arc, facilitated segments, and how a cardiac patient can present with T1-T5 tissue changes.

T1-L2 SNS vs S2-4 PSNS spinal level rules, splanchnic pathways, viscerosomatic palpation, and OMT targets that calm or fire each system.

CV4, EV4, fluid drive mechanics, four vagus-governed cranial nerves, and tap-to-reveal lesion patterns for CN III, VII, IX, X.

Deep buttock pain, sciatic nerve entrapment, figure-4 stretch, counterstrain vs muscle energy positioning, and the stretch matching game.

Anterior vs posterior fibular head. The seesaw model, muscle energy positioning, HVLA thrust. Interactive diagram + quiz.

Anterior or posterior: one rule, two directions. Play the catch game to build both dysfunctions, then run the quiz until neither catches you.

L-on-L, R-on-R, L-on-R, R-on-L. Forward vs backward torsion. The axis, the L5 finding, the ILA, and the treatment position. Morphing tabs + elimination game.
