graphs Flashcards
what do you need for a pedotti graph
the vertical, anterior, posterior force components and the centre of pressure on the plane of interest for each movement.
draw pedotti for heel strike
draw pedotti for loading
draw pedotti for midstance
draw pedotti for push off
draw pedotti for toe off
when is vertical force greater than body weight
after 10% of gait cycle
draw energy while walking
what can be seen as a inverted pendulum model and what as a double
walking, our stance leg is inverted and the swing leg is double.
when the freud number is above one what happends
the support limb comes off the ground.
who will easily get thier freud number over zero
kids, as to why they have to run faster and short legs. or less gravity
draw the energy while running
heel strike running GRF draw.
what happens in the heel strike GRF.
double peak in Fz, impact transient and push off. Fy shows braking and propulsion.
draw farefoot running GRF.
what happens in the farefoot GRF.
this is associated with carefoot/minimal shoe running. single peak: transiet rounded off by more gradual deceleration. load taken up by achilles rather than heel and compressive forces.
draw the gastrocnemius medialis activation in farefoot anf heel foot running.
draw the soleus activation in farefoot anf heel strike running.
which calf activation is eccentric and which is concentric.
gastroc. high eccentric early in fore foot stride.
soleus high concentric activation mid stance in rarefoot stride.
