LEG/ANKLE/FOOT - MUSCLES Flashcards
The more distal the fibres on the vastus medialis muscle, the more horizontal they become …what purpose does this have in terms of the patella?
stabalizes the patella
is the closed packed position of the knee the same as the ideal ROM for knee extension?
yes … 0 degrees
the hamstring muscle group is involved in flexion of the knee …name the other muscles involved (and identify which ones are weak)
gastrocnemius, gracilis, sartorius, plantaris (weak), popliteus
other than the 4 quadricep muscles, which muscle extends the knee as well?
tensor fascia lata
the 4 quadricep muscles are involved in knee extension. which one is a weak antagonist in this action?
vastus intermedius
name the antagonist muscle(s) on medial rotation of flexed knee
biceps femoris
name the antagonistic muscles on lateral rotation of flexed knee and identify which is weak as an agonist in medial rotation
semitendinosus, semimembranosus, gracilis, sartorius, popliteus (weak)
during flexion of the knee during an upright position, what movement happens at the tiobiofemoral joint in the first 20 degrees of flexion?
posterior roll of the femur (after that roll and slide)
which muscles cause passive insufficiency during knee flexion PROM
length of quadriceps
LOOSE PACKED POSITION OF KNEE
30 DEGREES
name the muscle that if present is part of the extensor digitorum longus and it’s origin and insertion
- peroneus tertius
- O: inferior anterior surface of fibula and interosseus membrane
- I: medial side of base of 5th metatarsal
