JOINT PLAY Flashcards
Joint play is defined as
the passive translatory gliding and distraction mobility that is characteristic of all the diarthrodial joints
loose pack position is the
position that the joint capsule and surrounding ligaments (inert tissues) are most relaxed
what position of the joint allows for greatest amount of joint play
loose pack position
Closed pack position
the position in which the joint capsule and ligaments are maximally taunt allowing minimal or NO joint play
osteokinematics
- movement of bone segment away from trunk or pelvis about joint axis
- patient can perform voluntarily
arthrokinematics/accessory motion
actual movements of articular or joint surface in relation to one another during osteokinematic motion
- joint must move through full range
- patient cannot perform voluntarily
joint play is used to assess ____________ motion
arthrokinematic
indications for performing a joint mobilization
- pain
- muscle guarding
- spasm
- joint hypomobility
absolute contraindications for performing joint mobilization
- suspicion of unstable fracture or dislocation
- suspicion of ligamentous tear
- malignancy
- advanced bone disease (like osteoporosis)
- active septic or infectious arthritis
Grade 1
-small amplitude movement at the beginning of the available joint play
Grade 2
large amplitude movement with the available joint play BUT not reaching the limit
Grade 3
large amplitude movement up to the limit of available joint play
Grade 4
small amplitude movement up to slightly beyond the limit of available joint play
Grade 5
manipulation- small amplitude high velocity thrust beyond the limit of available joint play
Joint traction is done __________ to the treatment plane
perpendicular
