Lecture 1 Flashcards
Intro
what are mobilizations?
passive manual techniques applied to joints + related soft tissues @ varying speed + amplitude
what is joint play?
amount of movement available between joint surfaces @ capsular level
what are physiologic movements?*osteokinematics
movements px can do voluntarily
what are accessory movements? *Also known as component movements
movements within the joint and surrounding tissues that are necessary for ROM but can not be actively controlled
what are arthrokinematics?
study of the movements that occur between the articular surfaces, inside
the joint (accessory movements)
what is congruency?
max achieved when articular surfaces have the tightest fit
what are normal end feels?
bone on bone
STA
tissue stretch/ ligamentous
muscular
capsular/firm
What are abnormal end feels?
muscle spasm
empty
springy
early bone on bone
boggy
muscular
capsular - before end range
what is subluxation?
incomplete or partial dislocation- often involves secondary trauma to surrounding soft tissue
what is manipulation?
thrust- high velocity, short amplitude-( patient cannot prevent)
what are the 2 shapes of joint surfaces?
ovoid + sellar
what is ovoid?
one surface convex
one surface concave
what is a sellar surface?
one surface convex in one direction - concave in the opposite ex. thumb/saddle
what is distraction?
joint surfaces pulled apart- require specific angle
what is compression?
joint surfaces approximated
what is roll?
one articular surfaces rolls on another
- always in same direc. as bone in motion+ associated with glide
what is spin?
accessory movement- bone moves in circular fashion around stationary imaginary axis
what is glide?
one articular surface glides on another
what are the benefits of joint mobilizations?
pain control
joint lubrication
improves tissue health
what are indications for joint mobilozations?
- pain + mm guarding
- reversible joint hypomobility
- positional faults/subluxations
- progressive limitation
- functional immobility
- poor proprioception
list absolute contraindications of joint mob./assessment
hypermobility + instability
acute inflammation
bone lesions
CT lesions
bacterial infection/ sepsis
excessive pain
spinal cord lesion
joint replacement
what are precautions in joint mobs.?
joint effusion?
prolonged corticosteroid
history neoplasm/radiation
osteoporosis
neurological signs
pregnancy- relaxin
what are the two systems for grading?
graded oscillation technique(maitland)
Sustained translatory techniques (kaltenborn)
what is grade 1 sustained?
small-amplitude distraction or glide applied where no stress is placed on capsule.
pain relief, non-corrective grade of mobilization.
