lumbar muscle energy

Question 1

muscle energy

Answer 1

first used by dr. mitchell sr DO

active/direct

Question 2

indications of muscle energy

Answer 2

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

Question 3

oculocertival (oculogyric reflex)

Answer 3

patient makes eye movements, certain cervical and muscles reflexively contract and antagonist muscles relax

Question 4

respiratory assistance

Answer 4

physician directs the forces of respiration while simultaneously uses a fulcrum to direct the SD through the barrier

Question 5

postisometric relaxation

Answer 5

mitchell jr

following increased tension on the golgi tendon receptors (contraction), there is a refractory period in which there is a muscle relaxation (lengthening)

Question 6

joint mobilization using muscle force

Answer 6

similar to HVLA but patient actively contracts muscles to cause movement

use patient positioning and muscle contractions to restore motion

Question 7

reciprocal inhibition

Answer 7

contract an agonist to relax the antagonistic muscles (biceps/triceps)

Question 8

muscle energy absolute contraindications

Answer 8

fracture, dislocation or severe joint instability at treatment site

uncooperative patient

Question 9

muscle energy relative contraindications

Answer 9

moderate to severe muscle strains
advanced osteoporosis
severe illness

Question 10

lumbar vertebral body

Answer 10

large size-designed to support postural weight
wedge shaped-higher in front, maintains lordosis
L4-at level of iliac crest

Question 11

vertebral processes

Answer 11

spinous process-same level as vertebral body

transverse process-long and thin, easiest to palpate distally

Question 12

intervertebral motion

Answer 12

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

Question 13

latissimus dorsi

Answer 13

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)

Question 14

hypertonicity in lat dorsi yields

Answer 14

pain in the shoulder

Question 15

gluteus maximus

Answer 15

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)

Question 16

erector spinae

Answer 16

origin&insertion: sacrum to cervical

includes: iliocostalis, longissimus, spinalis

action: bilateral contraction-extension
unilateral contraction-extending and ipsilateral sidebending

Question 17

quadratus lumborum

Answer 17

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

Question 18

multifidus and rotatores

Answer 18

postural muscles

action: controls and stabilizes individual vertebral motions

Question 19

iliopsoas consists of and action

Answer 19

psoas major and iliacus

action: hip flexion, lumbar sidebending (unilateral contraction),

Question 20

psoas major

Answer 20

origin-transverse process of T12-L5
insertion-lesser trochanter of femur

action-flexes and internally rotates hip

innervation-L1-3(2-4) ventral rami

Question 21

iliacus

Answer 21

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

Question 22

lumbar ligaments

Answer 22

anterior longitudinal

posterior longitudinal

Question 23

iliolumbar ligament

Answer 23

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

Question 24

lumbar muscle energy

Answer 24

account for all 3 planes of motion-coronal, horizontal, sagittal

Question 25

lumbar somatic dysfunction

Answer 25

subjective: low back pain, increased muscle tension, aching pain
objective-type 1 and type 2
