Leg stiffness Flashcards
1
Q
3 methods of measuring change in leg length?
A
Greater trochanter to foot marker (Grimmer et al., 2008).
Greater trochanter to point of force application (Stafilidis and Arampatzis, 2007).
Vertical position of trochanter to ground (Rapport et al. 2003).
2
Q
Equation?
A
Max GRF/Change in leg length
3
Q
Description?
A
Measure of resistance to change of leg length after application of internal/external forces (Serpell et al., 2012).
4
Q
When are leg stiffness and vertical stiffness calculated as the same?
A
When using prediction models during hopping/vertical jumping (with 0 horizontal displacement.
