lumbar disorders Flashcards
muscles affecting lumbar vertebrae functioning
multifidus
longissimus
spinal muscles
psoas major
function of LV
support
stability
weight bearing
truncal movements
load transfer
control leg movements
ligaments on LV
ligamentum flavum
anterior longitudinal ligament
posterior longitudinal ligament
spinal instability
laxity area around the spinal neutral segment
spinal stability model
passive subsystem
active subsystem
neural control subsystem
passive subsystem
composed of vertebrae
discs
facet joints
ligaments
active subsystem
muscles and tendon
neural control subsystem
CNS and spinal nerves
guide and control active system to ensure dynamic stability
dynamic stability
global muscle system
local muscle system
global muscle system
muscles with no direct attachment to the spine
produce large torques
no segmental effect on spine
muscles are
rectus abdominis
quadratus lumborum
external oblique
local muscle system
they have direct attachment to the spine
pelvic floor
transverse abdominis
multifidus
major core muscles
abdominals
diaphragm
internal and external oblique
erector spinae
multifidus
minor core muscles
latissimus dorsi
gluteus maximus
trapezius
strain
when muscle is stretched too far and tears or damaging itself
sprain
over stretching and tearing affects ligaments
