Question 7

Joint mobilization grade 1

Answer 7

“baby”
small amplitude mvmt performed at beginning of range

Question 8

Joint mobilization grade 2

Answer 8

“big”
large amplitude mvmt performed within the range, but not reaching the limit

Question 9

Joint mobilization grade 3

Answer 9

“big”
large amplitude rhythmic oscillations performed up to the limit of the available motion and are stressed into the tissue resistance

Question 10

Joint mobilization grade 4

Answer 10

“baby”
small amplitude rhythmic oscillations performed at the limit of the available motion and stressed into tissue resistance

Question 11

Joint mobilization grade 5

Answer 11

thrust
small amplitude, high velocity thrust technique performed to snap adhesion at the limit of range
