hi,

in our practice we use the stabilizer. under this link you will find some information about it.

i have made very good experience with it. it is very simple to use for patients, buit also very effective. you can use it for relearning a patient core stability, but do also advances exercises with extremity involvement.

i use it as a basic exercise for lower-back patients, since in 90% of all patients instability plays a big role.
besides this it has also a mobilising effect for the lws ( pelvis movement ),
which contributes very often to pain relieve.

hope that helps a bit!

cheers
