LCL
ACL
ALB OF PCL
meniscal femoral
what ligaments are taut with lateral rotation in the knee when it is flexed to 90°
MCL
PLB of ACL
at what degrees of the knee should the patella not move laterally or medially
60°
what mm should u strengthen if you loss ability of ACL
hammy
quads
soleus
glute max
abductors
why is there more DF with the knee flexed rather than the knee extended
bc the gastro is taken out (passive insufficiency when the knee is straight )
what is the best postion to stretch the gastroc
standing with foot on DF and knee extended (closed chain)
if PF strength stronger when the knee is flexed or extended
extedned bc the gastroc and soleus both working
describe the motion of the calcaneus , talar and tib fib during closed chain supination
calcenus IN
talar adb and DF
tib fib lateral rotation
describe the motion of the calcaneus , talar and tib fib during closed chain pronation
cal EV
talar ADD and PF
tib fib MED rot
when you rotate your tibia laterally what happens at the hindfoot and forefoot
HF does sup
FF does pro
when you rotate your tibia medially what happens at the hindfoot and forefoot
subtalar pronation
during the loading phase of gait there is ____ and during the push off the ankle is in ___ and during IC the ankle is in ____
pronation
neutral
supination
why is it important to strengthen the fib long and brevis after an inversion ankle sprain
bc the fib long and bre are primary prontaors
which bursa of the hip is most superficial
trochanteric
what positon would likely allow dislocation of the femur
flex and add
what musclse can produce adduction of the femur and medial rotation and flexion of the tibia
gracilis
if someone has tight bilateral ilisopsoas how will the pelvis and back be
APT
increase lumbar lordosis
what mm work in a force couple to move pelvis into APT
hip flexors and bacl extensors
what mm work in a force couple to move pelvis into PPT
hammy and abds
what mm work in a force couple to move pelvis into LPT
contra quad lum and ipsi glute med
if you are in hip flexion and knee extension which mm will have pasivie insufficiency
hammy (ST)
if you are in hip flexion and knee extension there will be ___ insufficiency of the rec fem
activie
if you are in hip extension and knee flexion there will be an ____ insuffiencey of the hip exnetors
acitve
how to stretch the glue max without the interference from the hamstrings
flee knee and flex hip and adduct
name the phases of single limb support
mid stance
terminal stance
swings (initial , mid and term)
name the phases of double limb support
IC
LR
preswing
during which phase is the pelvis the most foward
IC
when are the DF the most active and what type of contraction
during IC to LR and eccentric
when are the hip extensors most active
IC and LR
when is the Erector spinae most active
LR
