Joint Mobilization: What is it?

  • slow, passive joint movement

  • decreased p! and increase joint motion

  • preferable when jt capsule is tight

  • use w/ ROM exercises to improve flexibity

2
New cards

When would you use joint mobs?

  • pain

  • muscle guarding/muscle spasm

  • joint effusion

  • joint contractures

  • joint capsule adhesions

  • ligamentous contractures

  • malalignment of bony joint surface

3
New cards

Osteokinematics

  • Physiological joint movement of the bone

4
New cards

Arthrokinematics

  • Joint surface movement

  • guarantees normal + smooth jt movement

  • occurs w/ osteokinematics

  • distraction, compression, sliding, rolling, spinning

5
New cards

Swing

  • visible movement of long bone; movement of bony levers

  • measurable w/ goniometer

New cards

Distraction

  • Separation of jt surfaces

  • allows max jt separation and decreased pain

  • most common jt mob technique→ especially after surgery to decrease p!

  • do this parallel or perpendicular to long bone

Compression

  • Decrease of joint space btw surfaces

  • opposite of distraction

  • increase joint stability

  • crucial for cartilage health, BUT excessive compression can increase articular cartilage injury (i.e. meniscus tear)

  • proper compression promotes tissue health and synovial fluid

New cards

Rolling

  • convex and concave surfaces

  • always rolling same direction of the swing

  • always with sliding (glide) and spinning in normal joints

New cards

Sliding

  • Convex moving surface- opposite to swing

  • Concave moving surface- same to swing

<ul><li><p>Convex moving surface- opposite to swing</p></li><li><p>Concave moving surface- same to swing</p></li></ul><p></p>

New cards

Spinning

  • rotation around a stationary axis

<ul><li><p>rotation around a stationary axis</p></li></ul><p></p>

New cards

Concave-Convex Rule

Concave moving on Convex= same direction of slide and swing

  • ex: femur convex, tibia concave→ both moving superior

Convex moving on Concave= opposite direction of slide and swing

  • ex: humeral head convex, glenoid concave→ arm swings superior but slides inferior

12
New cards

Loose packed position

  • relaxed joint position

  • chose this most often for joint mobs

New cards

Close Packed Position

  • Locked Joint Position

14
New cards

Capsular Patterns

  • predictable pattern of motion loss observed when jt ROM limitations occur secondary to jt capsule tightness

  • jt mobs are necessary to normalize jt capsule mobility for complete ROM

15
New cards

Capsular Pattern: Talocrural jt

PF more limited than DF
