- 14 aspects of causationtemporal, specificity, reversibility, strength
- 2temporalbefore cause and effect
- 3specificitythis cause always leads to this effect
- 4reversibilitycut off cause, use effect
- 5Biomechanical plausibilityforces from an event imposed on an anatomical region are sufficiently high to exceed the tolerance limits of that region
-separate, measure causes and model effects
- - 6hippocratesdocumented relationships between fall height, landing surface and features, and head injury and fatality
- 7De Haven- examined post crash integrity of cockpit and seat hairness to understand how he avoided contact injuries
- 8Cairns- changed helmet design to just around sides and not crown
- 9laneplanes should be airworthy and crash worthy
- 10modelling injury effect(Abbreviated injury score)
- scored based off fatality rate
- minor, moderate, serious, severe, critical, maximum - 11Eadward Muybridgecreator of moving pictures
- 12david sutherlandinvented the ideas of motion capture
- frame to frame of the body - 13timeHow much time is between 2 consectutive samples
- serial samples vs real time samples - 14space/scaleconsistently accurate known relationship between video world spatial units and real world spatial units in multiple dimensions
- 15define and organizedspace and time relationship, X and Y direction
- 16space and time relationshipkinematics, how far in specific directions (displacement) how fast (velocity) the changing rate (acceleration)
- 17X and Y directionAngular kinematics, what size did the angle change between
- 18phases of whip lashlordosis position, retraction position, extension position, rebound position
- 19lordosis positionlordosis means concavity to the dorsal (anterior). neck flexes a bit as head gets left behind
- 20retraction positionretraction, forward motion of the spine and T1
- 21differential translation- parts are sliding and translating differently
- creates an S curve - 22extension positionends with contrast with head rest, refexivity of the neck, kinetic chain causes this
- 23rebound positionhead comes back around
