Midterm- Miscellaneous Flashcards
arthrokinematic: convex on concave =
roll/glide opposite direction
arthrokinematic: concave on convex =
roll/glide same direction
End Feel Ex: Soft
tissue compression (knee flexion)
End Feel Ex: Hard
bony stop (elbow extension)
End Feel Ex: Firm
capsular, ligamentous (ankle dorsiflexion)
Define extensibility
lengthening of muscle
Define elasticity
ability of muscle to return to normal length
Active Length/Tension Relationship
muscle produces max force near resting length (mid-range)
Active Insufficiency
muscle fully shortened and incapable of contracting to produce full ROM at both joints
Passive Insufficiency
muscle fully lengthened and incapable of stretching to extent required for full ROM at both joints
force-velocity relationship
speed of muscle contraction affects force generated by muscle (eccentric > isometric > concentric)
isometric contraction
muscle contraction without movement/position change
isotonic: concentric contraction
muscle contraction w/ shortening
(O&I move closer)
-usually against gravity
isotonic: eccentric contraction
muscle contraction w/ lengthening
O&I move away from each other
-usually with gravity
open kinetic chain
distal segment free
non-weight bearing
closed kinetic chain
distal segment fixed
weight-bearing
overload principle
load/demand on tissue must be greater than normal to adapt & make gains
SAID principle
(specific adaptation to imposed demands)
train w/ specificity to produce specific adaptation
reversibility principle
adaptations and progress are reversible
muscle spindles
monitor changes in muscle length
stimulated & “excitatory”
Golgi Tendon Organs (GTOs)
detect increase in muscle tension
inhibit motion when stimulated (cause relaxation)
MMT Grade 5/5
full available ROM against gravity & therapist’s max force
MMT Grade 4/5
-explain 4- & 4+
full available ROM against gravity & therapist moderate force
(breaks at max resistance)
MMT Grade 3/5
(starting point)
full available ROM against gravity (no resistance)
