Document Summary
Sagittal: bow and arrow cutting through centre of the spine. Frame of reference (not using cartesian or polar); diagrams are important (always add the frame of reference) Critical point a (load is transferred to the spine) Active tissue or muscle wire to express tension. Look at the centre of rotation (lever arms) Measure the point at the hand when it presses against a load cell. Generates resistivity with respect to the force of the hand. Force at the anchorage point (against the muscle) 0. 025 times 50 = fy times 0. 15+ 0. 15 fy= 4. 16 n (acting downwards) lost a relative amount of force (wasting energy with mechanical movement) (opposite of a nut cracker) Force that carries through ertia ( need acceleration and speed to generate enough force and momentum) Monitoring system for cumulative mild traumatic brain injury/concussion gerta liell-cock (headsafe company) Measure functional changes (pupil/visual cortex assessment) , balance/coordination, cognitive impairment.
