C8-T1

Question 18

What is structural differentiation

Answer 18

Allows us to differentiate between neural and non-neural structures

Question 19

If a change in symptoms is based on a differentiating maneuvre - symptoms are ___

Answer 19

neurogenic

Question 20

What is a positive neurodynamic test

Answer 20

reproduction of patients symptoms
structural differentiation gives a neural result
range of motion may be reduced

Question 21

What is not a positive neurodynamic test

Answer 21

contralateral testing: symmetrical response. e.g. bilateral tightness
Does not reproduce patients symptoms

Question 22

Which ULNT helps determine whether a patient has cervical radiculopathy

Answer 22

Median

Question 23

Does Median Nerve ULNT help diagnose carpal tunnel syndrome

Answer 23

No

Question 24

What is a slider

Answer 24

Sliders aim to induce sliding of the peripheral nerves in relation to their surrounding structures with a minimal increase in nerve strain

Achieved by simultaneous lengthening of the nerve bed at one joint while shortening the nerve bed over another joint

Question 25

What is a tensioner

Answer 25

Aim to increase nerve strain by simultaneously elongating the nerve bed at multiple joints
