Mod 3 queensland Flashcards
what % of people pass the TA test
10%
how does the muscular system componsate for instability
increasing stiffness of the L/S + decresing size of neutral zone
what is the local vs global system
local- serve a more proprioceptive role, closer to spine, need for stability
Global- generally more lat and responsible for moving heavy loads
which muscle/patt doest go silent during full flex
medial QL
how much does TA activation decreae extensor muscle contraction
12-20%
How does the TA fire and superficial muscles
Ta- tonic
Superficial- phasic
when does the diaphram and pelvic floor and during respiration turn on compared to the TA
diaphram same as TA
Pelvic floor same as TA
respiration delays TA activation
what are monoacrticular muscles and examples (3)
close, associated w joint
VMO, Rotator cuff, glut med
what is cocontraction good for and bad for
good- stability
bad- insufficient from an energy POV
if u just train the quads what happens to the hams
decreased cocontraction (less stability)
what is the downside to cocontraction
high compressive pentaly
In ind with petelo femoral pain what happens to VMO contraction
goes from tonic to phasic/eratic
what type of muscles is resistent to reflex inhibition and which are succeptible
single joint- more succeptible
multijoint- less affected by reflex inhibition
how is the queensland group different from other stabalization protocols (4)
- percise contraction of TA and multifidus
- decrease global activation
- selection of strat pt. specific
- tx continusly changes
3 steps of progression from queensland
- formal motor skills training
- gradual incorporation of skill into light functional tasks
- progression to heavy loaded tasks
