what are the 3 descriptions of ROM

Answer 4

direction (flexion, extensions, etc)
range (measurement in degrees)
quality

Question 5

Answer 6

elastic-rubber band
abrupt- osteoarthritis/hinge joint 
hard - SD
empty- patient gaurding

Answer 7

flexibility

Question 8

what are the 3 descriptions of flexibility

Answer 8

static- max ROM a joint can reach with external force

dynamic- ROM an athlete can reach and speed at which she can reach it

stiffness- reduced ROM of joint

Answer 10

coupled motion

ROM in spine
