what is joint effusion
excessive build up of fluid w/in jt
jt mobs are used to do what (2)
-modulate pain
-treat jt dysfunction that limits ROM
skilled passive manual therapy techniques applied to jts and related soft tissues at varying speeds and amplitudes
mobilizations
describes the amount of mvmt thats available b/w jt surfaces at a capsular level (“give”). Assessment tool
joint play
mvmts that the patient can do voluntarily. Osteokinematics is the study of these mvmts
physiologic mvmts
mvmts w/in the jt and surrounding tissues that are necessary for normal ROM but cannot be actively performed by the pt.
accessory mvmts OR component motions
study of mvmts that occur b/w articular surfaces, inside the jt (accessory mvmts)
arthrokinematics
articular surfaces have perfectly matching features allowing for a tight fit
congruency
position of the synovial jt where art. surfaces are maximally congruent
Closed-Packed position (CPP)
what position is a jt in when its capsule and ligs become taught and the jt surfaces of as close as possible
CPP
cartilage lubrication occurs in what position
CPP
where the joint surfaces are the least congruent and the ligs and capsule are relaxed
resting position
easiest position in which to mobilize
resting position
every other position other than CPP
loose-packed position
predictable pattern of restriction at occurs in a synovial jt when the capsule is the source of the problem
capsular pattern of restriction (CP)
normal end feels (3)
-bone on bone
-soft tissue approx
-tissue stretch->ligamentous, muscular, capsular
abnormal end feels
-mm spasm
-empty (pt stops you)
-springy (meniscus tear)
-early bone on bone
-boggy (jt effusion)
-muscular
-capsular (before reaching normal range)
a mm spasm that occurs early in PROM is likely d/t what
an injury
a mm spasm that occurs late in PROM is likely d/t what
instability
incomplete or partial dislocation
subluxation
high velocity, short amplitude motion that the pt cannot prevent (only for chiros)
manipulation
on top of having hypermobility, the amount of accessory mvmt is increased beyond normal for the jt
instability
