MSK basics Flashcards
what does loose pack position mean
min surface contact
max joint play
what does close pack position mean
max surface contact
max tension
what do we perform joint mobs in CPP or OPP
open packed position
what are grade II and I mobs for
pain
or
when muscle guarding is present
what are grad III and IV mobs for
increasing joint ROM
what does a grade I mob look like
slow with a small amp
at the beginning range of joint play
what does a grade II mob look like
slow with a large amp
within range but not reaching limit
what does a grade III mob look like
slow with large amp
in tissue resistance range (just the start)
what does a grade IV mob look like
slow w/ small amp
in the tissue resistance range the entire time
what does a grade V mob look like
high velocity
small amp thrust
at the limit of available ranges
hard endfeel
bone on bone
EX: elb ext
soft endfeel
tissue approximation
EX: elb flexion
firm endfeel
ligamentous stretching
EX: shoulder flexion
boggy endfeel
joint swelling
springy endfeel
meniscus displacement
empty endfeel
pain
rubbery endfeel
muscle spasm
isometric contractions
no change in muscle length
isotonic contractions - types and what
concentric and eccentric
change in muscle length while the force or tension remain the same
what is a concentric muscle contraction
the muscle length shortens
EX: lifting yourself up against gravity
what is eccentric muscle contraction
the muscle length gets longer
EX: lowering yourself against gravity
what is a isokinetic contraction
constant velocity muscle contraction that requires equitment
hypomobility at one joint can cause what
hyper mobility at another joint
compensations
what does excessive PF in stance lead to in the knee, hip, and back
hyperext of the knee
lumbar lordosis
and anterior pelvic tilt
think of someone wearing high heels
