    Section 02 -- Lifespan Evolution

    How gait, posture, and compression change with age

    From the wide-base toddler to the cautious 80-year-old, gait reorganizes around the body's capacity. The cervical, thoracic, lumbar, and pelvic orientations shift -- and with them, the compression load and pathology risk profile.

    Section 03 -- Sex Differences

    Female vs. male biomechanics -- anatomy meets neuromuscular control

    The sex gap in injury and pathology profiles is mostly mechanism, not destiny. Anatomy creates a default loading pattern -- but the neuromuscular system is modifiable.

    Section 04 -- Population Strategies

    Three populations, three intervention hierarchies

    The same eight phases -- but the leverage points differ. Switch the population to see modifiable concerns and the strategies that move the needle.
