1

Which muscles are tight in the lower cross syndrome?

Erector spinae and iliopsoas

2

Which muscles are weak in the lower cross syndrome?

Abdominal muscles, gluteus maximus

3

What is the neutral zone in reference to the spine?

Region of laxity around the neutral resting position of a spinal segment (between flexion and extension, for example)

4

According to Panjabi, how can neutral zone impairment lead to pain and disability?

Decrease in the capacity of the stabilizing system of the spine to maintain the intervertebral neutral zones within physiological limits

5

How does high-speed trauma affect a spinal segment's neutral zone?

Increases it

6

Biomechanically speaking, what is the most stable position for stress on the spine to be placed?

Within neutral zone

7

What things make up the passive system that influences the neutral zone?

Vertebrae, IVD, zygaphophyseal joints, ligaments

8

What things make up the active system that influences the neutral zone?

Muscles and tendons

9

What things make up the neural system that influences the neutral zone?

Central and peripheral nervous systems

10

What 3 large body concepts make up the overall stability of the spine?

Nervous system, spinal column, muscles

11

What muscles make up the core stabilizers?

Transversus abdominis, pelvic floor, diaphragm, multifidis

12

Which involves larger, torque-producing muscles that are anatomically more superficial: global system or local system of muscles?

Global: control spinal orientation and balance of external loads

13

Which involves anatomically deeper muscles that provide stability through increasing spinal segmental stiffness: global system or local system of muscles?

Local: play a role in anticipation of motion

14

When are the core stabilizers at work?

All times

15

When do the core stabilizers increase their action?

BEFORE any further loading or motion

16

Which pelvic tilt is utilized to find the neutral zone by drawing the belly up toward the rings and toward the floor while flattening the low back against the floor?

Posterior pelvic tilt

17

Which pelvic tilt is utilized to find the neutral zone by pushing the tail bone down and arching the low back up from the floor?

Anterior pelvic tilt

18

About how many muscle attachments make up the core area?

29

19

Which core muscles form the "core container"?

Pelvic floor, diaphragm, transversus abdomens

20

What additional muscles to the core function to stiffen the spine and stabilize the core?

Iliocostalis, longissimus, multifidi, rotators, intertransversarii (also ligaments and fascia, technically)

21

What are the extensors of the thoracolumbar spine?

Longissimus, iliocostalis, and multifidis

22

What is the thoracic portion of the erector spinae muscles that are extensors of the thoracolumbar spine?

Longissimus thoracis pars thoracics
Longissimus lumborum pars thoracis

23

What is the lumbar portion of the erector spinae muscles that are extensors of the thoracolumbar spine?

Longissimus thoracis pars lumborum
Longissimus lumborum pars lumborum

24

What is the origin of the pars thoracis?

Posterior sacrum and medial iliac crest

25

To where do the pars thoracis attach?

Ribs and vertebral components (run parallel to spine)

26

Is the pars thoracics mostly slow or fast twitch fibers?

Slow (type 1) (75%)

27

Is the pars thoracis a global/superficial muscle or local/deep?

Global/superficial

28

What is the function of the pars thoracics?

Produce greatest amount of lumbar extension with minimal compression of the spine

29

What is the origin of the pars lumborum?

Posterior sacrum and medial aspect of iliac crest

30

To where do the pars lumborum attach?

Mammillary and transverse processes of lumbar vertebrae
