Neurodynamic Mobility

Question 1

The nervous system is a electrical chemical and mechanical structure that is

Answer 1

Continuous

Question 2

Neural tissue Is a form of

Answer 2

connective tissue that has viscoelastic properties

Question 3

Neural Tissue allows for the transfer of mechanical stresses

Answer 3

throughout the system during movement

Question 4

Movements are passive and

Answer 4

related to surrounding tissues

Question 5

Elongation of the nerve and cliding in relation to surrounding tissues

Answer 5

up to 2 cm sliding / 10%elongation

Question 6

The dura forms a loose sheath around the spinal cord from the

Answer 6

foramen magnum to the coccyx

Question 7

Tethered to the spinal canal to provide stability for the spinal cord

Answer 7

foramen magnum, coccyx

c6, t6, l4elbow shoulder and knee

Question 8

Neural tissue adapts to movements of

Answer 8

joints and muscles

Question 9

Moves in relationship to

Answer 9

tension sites and joint axis

Question 10

Adhesions can result in

Answer 10

excessive stress in that area

Question 11

Sites of nerve vulnerability; tunnels

Answer 11

compression, friction, response to other tunnel contents

Question 12

Site of vulnerability: Branches

Answer 12

less mobility at sites of branching

Question 13

Site of vulnerability: Hard Interfaces

Answer 13

nerve is more easily compressed against a bone r passing through fasica

Question 14

site of vulnerability: Proximity to the surface

Answer 14

more vulnerable to external compression

Question 15

Neural tissues respond to injury as any other connective tissue

Answer 15

Inflammatory cascade
Pain with stress
Formation of fibrous tissue
adhesions in the nerve sheath or surrounding tissues

Question 16

Nerves and their microcirculation can be affected

Answer 16

by tension, friction, compression

Question 17

Double Syndrome

Answer 17

Proximal compression/ irritation of a nerve may make the nerve more susceptible to compression distally

• -cervical radiculopathy could precipitate carpal tunnel on the same side
• -Due to disruption of the axons, impaired axonal transport, endoneural edema, or ischemic changes in the nerve.

Question 18

Test are designed to stretch the dura to assess the contribution of the neural tissues to the patient’s concordant sign.

Answer 18

Slump test
Straight Leg Raise
Well Straight Leg Raise (Crossed SLR)
Upper Limb tension Test 1
Upper Limb Test  2
Upper Limb Test 3

Question 19

Slump test

sensitivity and specificity about the same

Answer 19

Pt sits with arms behind back
instruct the patient to slump the back into full thoracic and lumbar flexion
apply overpressure across the patients shoulders
Pt actively flex the cervical spine (chin to chest) and
apply overpressure to the back of the head to maintain flexion
Dorsiflex the foot
Instruct the patient to actively extend the knee as much as possible
If unable to fully extend the knee, release overpressure of the cervical spine and allow patient to extend the neck
If the patient is able to extend the knee further with cervical extension or symptoms are reduced, the test is positive implicating dural, cord, or nerve root restriction

Question 20

The slump test is for

Answer 20

lumbar radiculopathy (may also be a way to pick up a central stenosis or disc herniation that does not present individually with pain)

Question 21

Straight Leg Raise

more sensitive .97

Answer 21

For lumbar radiculopathy:pain before 70” (at 30” acute Disk herniation)
Sensitizers are: (add in to add tension to the test and can be used as treatment technique)
Dorsiflexion
Cervical Flexion
Hip Internal rotation

Question 22

Well straight Leg Raise

most specific -1.00

Answer 22

Most specific of test for the lower extremity:
Raising the uninvolved side and reproducing pain on the involved side.
Lumbar HNP(Herniated Nucleus Propulsus)/radiculopathy

Question 23

If picking one test to see what is really going on as far as lumbar radiculopathy

Answer 23

SLR and Well Straight Leg Raise

Question 24

Cluster for HNP

Answer 24

Severely limited SLR
+ Well SLR
severely restricted and painful lumbar rotation

Question 25

Upper Limb Tension Test 1 (ULTT 1)

Answer 25

Median Nerve 
Pt Position: supine
Depress the shoulder girdle
extend the wrist and fingers
supinate the forearm
abduct the shoulder 110" then externally rotate
extend the elbow

Question 26

UTLL 2

Answer 26

Radial Nerve
Scapular depression
elbow extension/ pronation
medial rotation
finger and thumb flexion
wrist flexion then ulnar deviation

Question 27

UTLL 3

Answer 27

Ulnar Nerve Bias
Scapular Depression
Shoulder abduction, ER
Forearm pronation
Wrist and finger extension
elbow flexion
full shoulder abduction
