OMM question

[chokiepie]

Hello,
This is question for the 2nd, 3rd and 4th year DO students. I'm a first year and have an OMM exam tomorrow and am freaking out. So, heres a question and i'll really appreciate if ya'll can help.

If it is easier to go from right to left (on the cervical vertebra) than from left to right, then you are rotated left, right?

Is this correct?

Make up whatever you want (see this thread).

SD is named -- for whatever reason -- for the direction of freedom of movement and not restriction. A segment that is rotated right is actually restricted in left rotation and moves more in right rotation.

I don't understand bio-mechanically why that is, but whatever.

The cervical spine is a bit confusing. Savarese says, "If C3 is restricted in right translation in the flexed position, then C3 is ESRr". Isn't this opposite of everything else? I thought SD was named for the direction of FREEDOM, not restriction.

I think this is because lateral translation produces sidebending in the opposite direction, but rotation and sidebending occur to the SAME side in C2-7. So pushing Left -> Right (right translation) induces LEFT sidebending. If right translation is restricted, then you have restriction in LEFT sidebending and LEFT rotation, so your freedom of movement is in RIGHT translation and sidebending. Thus, That segment will be diagnosed as the same direction as translation.

Glad I didn't have any cervical crap on Level I
