Sliders vs Tensioners

[bernard]

Hi All,

I found that one on NOI

http://www.noigroup.com/cgi-bin/ubbcgi/ultimatebb.cgi?ubb=get_topic;f=5;t=000098

Before doing a comment about it, I need a bit of explanation.

What is the difference between sliders and tensioners?

Thanks!

A good example is the slump test.

Sitting, SLR plus ankle DF with neck flexion (PNF) = tensioner
Sitting, SLR plus ankle DF with neck extension = slider

All you need to do is think of the anatomy; and the tension points in the neural system from head to toe - C5C6, T4-6, L1-L3, sciatic notch, posterior knee.

Lying, ULNT 1-4, add neck LF/Rot to contralateral side-->tensioner
Lying, ULNT 1-4, add neck LF/Rot to ipsilateral side--> slider.

Nari,

I think that I was too theoretical about sliders and tensioners. I understand clearly the principle but I miss certainly some practical reasonning here?.

Take a human being with a huge sciatica with some high defense in low back (tightness). If I try firstly a SLR (sciatica sided), to slide the nerve, it will fail (in my view) because of the tightness and fails in the tensioner too (whole tension).

There is a hot spot which is like an anchor and stops the normal sliding and tensioning. This anchor splits the tensioned/slided nerve in two?

Perhaps silly questions?

Hi Bernard:

Try to put your question in a more clearer point , or give another example.

I think there is a need of imaging? :?

[emad]

well , i wait , and looking forward to see that designed picturised question.

Hi Somasimplers,
Here is a slider in my view?
There is also a bit of tension at the end of movement because the nerve is only a bit elastic.

Hi Somasimplers,

Here is a tensioner in my view?

Hi Somasimplers,

Here is a slider which is now a tensioner! An obstacle may transform the purpose of the neural mobilization?

Here is animation showing a possible problem when trying to slide a branch of a nerve (i.e. a finger). It works fine for the finger itself if it is mobilized by the peripheral side but fails to slide at a higher place (upper than the fork).

If you want to slide the whole branch, you need to pull on all branches. Of course, it works also by the upper side but often we have no access to this side. So it is easier to work on the peripheral branches
