lumbar stabilization

Question 1

what are the three management approaches in the panjabi model of lbp?

Answer 1

medical management
rehabilitation management
self-care management

Question 2

what are three rehabilitation approaches in the panjabi model of lbp?

Answer 2

symptom modulation
movement control
functional optimization

Question 3

what is the closed system of lumbar stabilization?

Answer 3

control: neural
passive: bone-ligament-disc
active: muscle

Question 4

what is are three components of the neutral zone hypothesis?

Answer 4

• 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

Question 5

what mechanisms of the expansion of the neutral zone mechanism would lead to instability?

Answer 5

attenuation of passive stabilizers

Question 6

abs keep you from falling forward or backward?

Answer 6

backward

Question 7

what type of muscular control do intrinsic back muscles use for counteraction of flexion?

Answer 7

isometric or eccentric

Question 8

what are the two pieces of the longissimus thoracis?

Answer 8

pars thoracis

pars lumborum

Question 9

describe the pars thoracis, area and type of moment?

Answer 9

spans the thoracic and lumbar regions
larger extensor moment
superficial

Question 10

describe the pars lumborum, where is it, type of action, force, etc.

Answer 10

runs from psis to lumbar vertebrae
extends and applies posterior shear force
deeper

Question 11

what action is being resisted by an extension moment?

Answer 11

flexion

Question 12

when is peak emg activity of the erector spinae? when is the greatest moment arm of the erector spinae? same or different?

Answer 12

peak: slight forward flexion
greatest moment arm: full fold
not the same-discs and ligaments doing the work at bottom

Question 13

in patients with chronic lbp, what is the activation dysfunction of the erector spinae?

Answer 13

erector spinae seem to stay active the whole movement

Question 14

if i side bend to the r, which side are my erector spinae most active on?

Answer 14

left

Question 15

if i have positive results for neural tension tests, what is the treatment?

Answer 15

neural mobilization

if symptoms aggravated, reclassify patient into symptom modulation

Question 16

if i have positive results for joint tests, what is my treatment approach?

Answer 16

manual therapy for joints

manipulation and mobilization

Question 17

if i have positive results for soft tissue tests, what is my treatment approach?

Answer 17

manual therapy including passive stretching and soft tissue mobilization
