joint mobs study guide

difference between mobilization and manipulation

manipulation uses over-PROM for soft tissue while mobilization uses joint movement to specifically address inter-articulate tissues

joint mobilization goal

normalize joint mechanics by
addressing joint capsule restrictions

what is known as the active or passive ROM around a joint or bone

osteokinematics

what is swing

the visible ROM of a joint
 Measured by a goniometer
 Example: shoulder flexion, hip abduction

what is separation of joint surfaces through the application of force

distraction

what is decrease in space between two joint surfaces

compression

when does rolling arthrokinematic occur

when two surfaces are incongruent

when does sliding arthrokinematic occur

on congruent surfaces

when does spinning arthrokinematic occur

when one bone rotates around a stationary axis

The Concave–Convex Rule

If the moving surface is concave, the slide is in the same direction as
the swing.
 If the moving surface is convex, the slide is in the opposite direction of the swing

loose-packed position

 A position where the ligaments and joint capsule
are relaxed and joint play is maximized
 Allows for articulating joint surfaces to be
maximally separated

Close-packed position

 A position of maximal bony congruency within the
joint, ligaments and joint capsule are tight
 No joint play occurs in this position, not the
position for joint mobilizations

what is the name of a predictable pattern of motion loss observed when joint ROM limitations occur secondary to joint capsule tightness

capsular pattern

If a capsular pattern exists,__________________ are necessary

joint mobilizations

joint mobs stimulate mechanoreceptors, which do this

 Decrease pain
 Improve joint proprioception
 Decrease muscle guarding and spasm

muscle energy technique

additional form of manual therapy uses
active contraction of muscles to provide the
desired accessory joint motion

we have to make sure/wonder is joint limitations are due to what?

 Pain?
 Capsular or ligamentous tightness?

joint mob indicators

 Reduction of joint pain
 Reduction of muscle guarding related to joint dysfunction
 Reduction of muscle spasm related to joint dysfunction
 Reversal of joint hypomobility
 Minimization of ROM loss associated with injury

joint mob precautions

 Malignancy
 Bone disease
 Unhealed fractures
 Excessive pain
 Hypermobility
 Total joint replacements
 Newly healed structures
 Geriatric patients

joint mob contraindications

 Joint hypermobility
 Joint effusion
 Acute inflammation
