pjm Flashcards
what is the main rationale for PJM
to modulate pain and joint LOM by correcting altered joint mechanics
what are the usual causes for altered joint mechanics
pain and MG
jt effusion
capsular adhesions
ligament adhesions
aberrant joint motion
diff PJM stretching from normal stretching
PJM addresses capsular tissue restriction by replicating loss arthrokinematics
stretching only stretches muscle and not joint capsule
exp mobilization or manip
passive manual therapy at varying speeds and ampli
using physiologic and accessory motions
discus self-mob or automob
self-stretching that uses joint traction or glide to stretch capsule
dicuss MWM
sustained accessory mob and active movement
able to to passive end range over pressure s pain
when is MWM applicable
no contra for manual therapy
(+) local MSK pathology
localized loss of movement or pain c function
(-) pain during and after appli
example of MWM
belt on post ankle while PT applies anterior glide to talus while pt dflexes ankle
discuss thrust
high velocity short ampli
done and end of pathologic limit
only once
thrust is intended to ______
alter pos rela
snap adhesions
stim joint receptors
discuss muscle energy
appli of active isometric contraction = desired accessory motion
isometrically contract hams to pull pelvis backward in SI joint dysfunction
what are physiologic movements
voluntary - osteokinematics
elbow flex/ext
what are accesorry movements
involuntary and has 2 kinds
component - accompanies active motion but not under volu control; shoulder abd and clavicle tilts up
joint play - arthro; necessary for nomal jt function
what is swing
angular rot of a lever c roll, slide or spin
elbow flexion
what is roll
same direction as the movement of lever
elbow flexion - ant roll
discuss glide/slide/translation
convex moving - opposite direction of roll; shoulder abd - sup roll and inf glide
concave moving - same direction of roll; elbow flexion - ant roll and glide
discuss spin
rolling + gliding
usually shoulder flex/ext, hip flex/ext, radiohum pron/supin
shoulder flexion - posterior spin
compare joint-glide stretching and passive angular stretching in terms of intensity
joint-glide stretching - modulates intensity based on pathology
passive angular stretching - cant be modulated
compare joint-glide stretching and passive angular stretching in terms of effect on joint
joint-glide stretching - replicated normal arthro and does not compress
passive angular stretching - causes compress and may inc pain
compare joint-glide stretching and passive angular stretching in terms of effect on pt
joint-glide stretching - stretch tight capsule
passive angular stretching - stretch tight muscle
discuss compression
dec jt space - during WB or for stab
during rolling, compression on angulating side
