Joint Mobilization
2
Basic Definitions

• Osteokinematics
• Arthrokinematics
• Related Terms
• Component Motions

3
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

4
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

5
Athrokinematics involved in Motion

• Roll
• Glide (Sliding)
• Spin
• Compression
• Distraction or Traction

6
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

7
Concave-convex rule
8
What is the difference between passive stretching
and joint mobilization stretching?

• Passive Angular Stretching
• Use a lever
• Joint Mobilization
• Safer more selective because

9
Techniques in Joint Mobilization

• Joint Position
• Closed packed position
• Loose packed position
