Define joint play
passive, involuntary arthokinematic motion occurring between two joint surfaces during movement
Describe the joint mob effects
Mechanical
- stretch of capsule
Neurophysiological
- enhancement of sensorimotor system
Describe an assessment glide
- single translatoric glide in which one bony surface is stabilized and the other is mobilized
- performed close to joint line
- loose packed position
Define where the "treatment plane" occurs
- passes through the joint and lies at a right angle to the line running from the axis of rotation (in the covex bony partner) to the middle of the contacting articular surface
- lies across concave articular surface and moves with the concave joint partn
Describe joint mobilziation
passive therapeutic technique intended to increase arthrokinematic motion to relieve pain
Describe the relationship between congruency and glide
The more congruent the greater the glide and vice versa
Describe the convex-concave rule
when a concave surface moves on a stabilized convex surface the arthokinematic movement will occur in the SAME direction as the osteokinematic movement of the bony segment
What direction is a glide performed
parallel to the treatment plane
What direction is traction performed
perpendicular to the treatment plane
Describe a grade I joint mob
SMALL amplitude
FAST oscillation
Beginning of range
Describe grade II joint mob
LARGE amplitude
SLOW oscillation
First 1/2 of range
Describe a grade III joint mob
LARGE amplitude
SLOW oscillation
2nd 1/2 of range
Describe grade IV joint mob
SMALL amplitude
Fast oscillations
End of range
Which joint mobs are used for what
Grade I and II treat pain
Grade III and IV increase motion
