lumbar muscle energy Flashcards
muscle energy
first used by dr. mitchell sr DO
active/direct
indications of muscle energy
mobilize joint i which movement is restricted
stretch tight muscle and fascia
improve local circulation
alter related respiratory and circulatory function
balance neuromuscular relationships to alter muscle tone
oculocertival (oculogyric reflex)
patient makes eye movements, certain cervical and muscles reflexively contract and antagonist muscles relax
respiratory assistance
physician directs the forces of respiration while simultaneously uses a fulcrum to direct the SD through the barrier
postisometric relaxation
mitchell jr
following increased tension on the golgi tendon receptors (contraction), there is a refractory period in which there is a muscle relaxation (lengthening)
joint mobilization using muscle force
similar to HVLA but patient actively contracts muscles to cause movement
use patient positioning and muscle contractions to restore motion
reciprocal inhibition
contract an agonist to relax the antagonistic muscles (biceps/triceps)
muscle energy absolute contraindications
fracture, dislocation or severe joint instability at treatment site
uncooperative patient
muscle energy relative contraindications
moderate to severe muscle strains
advanced osteoporosis
severe illness
lumbar vertebral body
large size-designed to support postural weight
wedge shaped-higher in front, maintains lordosis
L4-at level of iliac crest
vertebral processes
spinous process-same level as vertebral body
transverse process-long and thin, easiest to palpate distally
intervertebral motion
flexion/extension- primary motion in lumbar
facets align backward and medial, couples with ventral-dorsal translatory slide
sidebending-couples with contralateral lateral translatory slide
rotation-couples with disk compression
latissimus dorsi
origin- T7-12, iliac crest, thoracolumbar fascia
insertion-humerus (intertubercular groove)
action: adducts, extends, internally rotates arm, extension and sidebending of lumbar spine
innervation-thoracodorsal nerve (c6-8)
hypertonicity in lat dorsi yields
pain in the shoulder
gluteus maximus
origin-thoracolumbar fascia, dorsal sacrum, sacrotuberous ligament, ilium
insertion- iliotibial band, greater tuberosity of femur
action-extends hip and stabilizes torso
innervation-inferior gluteal nerve (L5, S1-2)
erector spinae
origin&insertion: sacrum to cervical
includes: iliocostalis, longissimus, spinalis
action: bilateral contraction-extension
unilateral contraction-extending and ipsilateral sidebending
quadratus lumborum
origin-12th rib, lumbar transverse processes
insertion-iliolumbar ligament, iliac crest
action-bilateral contraction creates extension, unilateral contraction causes extension with ipsilateral sidebending
innervation-T12 and L1-4 ventral rami
multifidus and rotatores
postural muscles
action: controls and stabilizes individual vertebral motions
iliopsoas consists of and action
psoas major and iliacus
action: hip flexion, lumbar sidebending (unilateral contraction),
psoas major
origin-transverse process of T12-L5
insertion-lesser trochanter of femur
action-flexes and internally rotates hip
innervation-L1-3(2-4) ventral rami
iliacus
origin-superior 2/3 of iliac fossa, inner lip of iliac crest. ventral sacroilliac and iliolumbar ligaments. upper lateral sacrum
insertion-lateral tendon of psoas
lumbar ligaments
anterior longitudinal
posterior longitudinal
iliolumbar ligament
attaches: transverse processes of L4-5 and iliac crest
increases stability at the lumbosacral junction(commonly strained in traumatic injuries)
first ligament to become tender with posture changes
lumbar muscle energy
account for all 3 planes of motion-coronal, horizontal, sagittal
