Y
axis
·
Translateà Distraction and compression
·
Rotateà Right/Left rotation
·
X
axis
·
Translateà Shearing or lateral glide, do not occur in
an active way but occur passively
·
Rotationà flexion/extension
·
Z
axis
·
Rotationà lateral bending
·
Translationà A-P glide
·
Rotation
can occur under active motion but translation must be done to you or done
passively
·
Transaltory
motion- is usually called accessory motion
·
If
the spine is healthy than the spine should be able to rotate and translate in
all six degrees of freedom.
·
Accessory
motion is lost before the rotatetory motion is lost, therefore people are
unaware that they have lost this
·
Most
orthopedic evaluations are translatory motion along the y axis.
·
When
this fixated adjusted the adjustment should be aimed at the restoration of
translation motion and is directed toward patients who have degeneration in
order to maintain rotation in the spine.
·
Exercises
can be given to restore translation type movement.
