lumbar stabilization Flashcards
what are the three management approaches in the panjabi model of lbp?
medical management
rehabilitation management
self-care management
what are three rehabilitation approaches in the panjabi model of lbp?
symptom modulation
movement control
functional optimization
what is the closed system of lumbar stabilization?
control: neural
passive: bone-ligament-disc
active: muscle
what is are three components of the neutral zone hypothesis?
- neutral zone: area where joint is freely moveable and not constrained by passive stabilizers
- muscle is key stabilizer in neutral zone
- if passive stabilizers (in disc) become weakened, neutral zone becomes larger creating more motion and a greater demand on system
what mechanisms of the expansion of the neutral zone mechanism would lead to instability?
attenuation of passive stabilizers
abs keep you from falling forward or backward?
backward
what type of muscular control do intrinsic back muscles use for counteraction of flexion?
isometric or eccentric
what are the two pieces of the longissimus thoracis?
pars thoracis
pars lumborum
describe the pars thoracis, area and type of moment?
spans the thoracic and lumbar regions
larger extensor moment
superficial
describe the pars lumborum, where is it, type of action, force, etc.
runs from psis to lumbar vertebrae
extends and applies posterior shear force
deeper
what action is being resisted by an extension moment?
flexion
when is peak emg activity of the erector spinae? when is the greatest moment arm of the erector spinae? same or different?
peak: slight forward flexion
greatest moment arm: full fold
not the same-discs and ligaments doing the work at bottom
in patients with chronic lbp, what is the activation dysfunction of the erector spinae?
erector spinae seem to stay active the whole movement
if i side bend to the r, which side are my erector spinae most active on?
left
if i have positive results for neural tension tests, what is the treatment?
neural mobilization
if symptoms aggravated, reclassify patient into symptom modulation
