Summary Grades of mobilization/manipulation

Grades of
mobilization/manipulation
Grade I

– a small amplitude movement performed at the beginning of the
available range. Usually performed as a slow smooth oscillatory
movement.


Grade II

– a large amplitude movement performed within a resistance-free part
of the available range. If performed near the beginning of the available
range, it will be classified as a grade II-, and if taken deep into the range,
yet still not reaching resistance, it will be classified as a grade II+


Grade III

– a large amplitude movement performed into resistance or up to the
limit of the available range. If the movement is carried firmly to the limit
of the available range it is expressed as a grade III+ but if it nudges gently
into the resistance yet short of the limit of the available range, it is
expressed as a grade III-.


Grade IV

– a small amplitude movement performed into resistance or up to the
limit of the available range. Can be expressed as 4+ or 4- in the same
way as grade III.


Grade V

– a small amplitude, high velocity general movement performed usually,
but not always, at the end of the available range.
