Joint Mobilization

Basic Definitions

Osteokinematics Arthrokinematics Related Terms

Component Motions

Athrokinematics involved in Motion

Roll New points on one

surface come in contact with new points on the opposite surface

Always occur in same direction as bone movement

When roll occurs alone:

Athrokinematics involved in Motion

Roll Glide (Sliding)

One specific point comes in contact with new points on opposing surface

Direction depends on surface of joint

Combined roll and glide movements

Athrokinematics involved in Motion

Roll Glide (Sliding) Spin Compression Distraction or

Traction

Convex Concave Rules

MUST KNOW Convex Stationary + concave moving =

gliding in same direction as angular motion

Concave stationary = convex moving = gliding in opposite direction of angular motion

Concave-convex rule

What is the difference between passive stretching and joint mobilization stretching? Passive Angular Stretching

Use a lever

Joint Mobilization Safer more selective because:
