Joint Mobilization

joint mobilization

skilled passive movement of a joint

osteokinematics

Movement of a limb that is visible.

arthorkinematics

movement of joint surfaces

different arthrokinematics motions

roll

slide/glide

spin

compression

distraction

convex/concave rule

if a convex is moving on a concave, the slide and roll are in the opposite direction of the movement of the bone

if a concave is moving on a convex the the slide and roll is in the same direction of the movement of the bone

closed vs open pack position

closed pack - stiff, capsular/ligamentous tightness

open pack - loose, capsular/ligamentous laxity

contraindications for joint mobs

unstable/hypermobile joints

specific malignancy

fracture

joint mobility scale

0 - no movement

1 - considerable decreased movement

2 - slight decreased movement

3 - normal movement

4 - slight increased movement

5 - considerable increased movement

6 - complete instability

grade I joint mobilization

small amplitude at beginning of joint play

empty end-feel

why would you use a grade joint mobilization

pain relief

grade II joint mobilization

large amplitude at the midrange of joint play

empty end-feel

why would you use a grade II joint mobilization

pain, spasm reduction

grade III joint mobilization

large amplitude at the end range of the joint play

function of a grade III joint mobilization

increase mobility

grade IV joint mobilization

small amplitude at the end range of the joint play

function of grade IV joint mobilization

increase mobility

grade V joint mobilization

manipulation of high velocity and low amplitude
