what does dorsiflexion cause the fibula to do

Answer 43

move superiorly causing the proximal/superior tibiofibular joint to be stressed

Question 44

in the GAIT cycle what does the tibia do during swing phase

Answer 44

tibia internally rotates (knee flexion)

Question 45

what does the tibia do during knee extension in the GAIT cycle

Answer 45

the tibia externally rotates during the stance phase (knee extension)

Question 46

rotation of the femur occurs automatically between full extension 0 degrees and 20 degrees of knee flexion

Answer 46

during knee extension the tibia glides anteriorly on femur and PCL elongates during last 20 of knee extension, anterior tibial glide persists on tibia medial condyle prolonged ant. glide on medial side produces external tibial rotation
