Q

What pressure range can restrict blood flow to nerves?

17
Q

How does tension affect the spinal cord?

A

Reduces blood flow

18
Q

What are the two mechanical dysfunction types involving nerve closing?

A

Reduced and excessive closing

19
Q

Which movement is provocative in reduced opening dysfunction?

A

Opposite side movement

20
Q

What dysfunction is associated with hypermobility and excessive postures?

A

Excessive opening

21
Q

Name two anatomical dysfunctions that can affect nerves.

A

Disc protrusions, stenosis

22
Q

What physiological factor can impair nerve root function without compression?

A

Proximity of the nucleus pulposus

23
Q

What is a common symptom of reduced neural sliding?

A

Excess tension and strain on nerves

24
Q

What is the goal of slider neural techniques?

A

Restore movement and blood flow

25
What is the aim of tensioner neural techniques?
Apply gentle tension to reduce sensitivity
26
What dysfunction occurs with reduced nerve sliding?
Sliding dysfunction
27
What does tension dysfunction in nerves cause?
Abnormal or undesirable tension dynamics
28
What is the balance required for INBF?
Between vasodilation (nociceptive) and vasoconstriction (sympathetic)
29
What is the role of epineurium during nerve compression?
Absorbs pressure
30
What is the effect of repetitive mechanical stimulation on INBF?
Likely increases blood flow
