kinesiology 4 Flashcards
Arthrokinematics
end feel
the type of resistance that a clinician feels when bringing a patient’s joint to the end of its passive range of motion, then applying a slight overpressure.
soft end feel
occurs when muscle bulk is compressed
soft tissue approximation
soft end feel
firm end feel
results from tension in the surrounding ligaments, capsule, and/or muscles and is perceived as a firm stop to the motion with only a “slight give” on overpresure.
hard end feel
characterized by a hard and abrupt limit to passive joint motion with no give on overpressure
bony end feel
hard end feel
boggy end feel
often found in acute condition in which soft tissue edema is present
muscle spasm
a reflexive muscle guarding during motion, a protective response
empty end feel
hen movement produces considerable pain and the patient stops the clinician from moving the joint beyond the painful point. End of PROM was not reached, unknown
springy block
a rebound movement is felt at the end of the ROM
arthrokinematic motion
the manner in which adjoining surfaces move on each other during osteokinematic joint movement
osteokinematic motion
joint motion
arthrokinematic motion
joint surface motion
component movements
small arthrokinematic joint motions that accompany active osteokinematic motion.
joint play
the arthrokinematic movement that happens between joint surfaces when an external force creates passive motion a t the joint
arthrokinematic motions
roll, slide, glide
nge tha is just past whe the joint ends.
a technique that applies an external force to a patient’s joint to generate a passive oscillatory motion, or sustained stretch between the joint surfaces.
High Velocity, Low Amplitude (HVLA) thrust manipulation
involves moving the joint with high speed through a very slight and calculated range that is just past where the joint play ends.
Traction forces
used with joint mobilization, causes joint distraction in which the joint surfaces pull apart from one another
compression force
used with joint mobilization, causes joint approximation in which the joint surfaces are pushed together.
shearing force
used with joint approximation, causes a gliding motion in which the joint surfaces move parallel to one another
bending
occurs when an other-than-vertical force is applied, resulting in compression on the concave side and distraction on the convex side. Rotary or torsional forces involve a twisting motion. One force is trying to turn one end or part through a longitudinal axis while the other force is fixed to turning in the opposite direction.
ovoid bone
has two bones forming a convex-concave relationship.
sellar
one joint surface is concave in one direction and convex in another.
saddle-shaped joint
sellar joint
roll
the rolling of one joint surface on another. new points on each surface come into contact with each other throughout the motion
glide
is linear movement of a joint surface parallel to the plane of the adjoining joint surface one point on a joint surface contacts new points on the adjacent surface
spin
the rotation of the movable joint surface on the fixed adjacent surface. Essentially the same point of each surface stays in contact with each other
concave-convex rule
shape determines the motion
concave joint surface
glides in the same direction as the distal end of the same bony segment
convex joint surface
glides in the opposite direction as the distal end of the same bony segment
congruent
the joint structures have maximum contact with each other, are tightly compressed, and difficult to distance(separate)
close-packed
congruent
close-packed
closed-pack, position
open-packed
loose-packed position
open-packed
resting position
mobilizing a joint
distraction, gliding, bending, or torsional forces may be used
joint approximation
may be used to promote joint stability
