does our line of gravity run anterior or posterior to our hip and what does this do to our joint when standing
posterior - which pushes our hip into extension
does our line of gravity run anterior of posterior to our knee and what does this do to our joint when standing
anterior - which pushes our knee into extension
does our line of gravity run anterior or posterior to our ankle and what does this do to our joint when standing
anterior - which pushes the joint into dorsiflexion
of the hip, knee and ankle which joint is not locked when standing and requires energy to keep us standing
the ankle
when the hip is in flexion are the anterior and posterior ligaments taut or lax (sitting)
anterior are lax and posterior are taut
what order and the 6 stages of bipedal walking in
early stance
mid stance
late stance
early swing
mid swing
late swing
in early stance where is the hip and what are the agonists
in flexion but moving into extension - gluteus Maximus and hamstrings
in early stance where is the knee and what are the stabilisers
in extension (locked for stability) - quadriceps femoris and hamstrings and gastrocnemius
in early stance where is the ankle and what is the agonist and antagonist
in dorsiflexion (stable - best body congruence), but moving into plantar flexion - agonist is triceps surae - antagonist is tibialis anterior which is needed to control the rate of foot drop
in mid stance where is the hip and what are the agonists
continuing to move into extension - agonists are gluteus Maximus and hamstrings
in mid stance where is the knee and what are the agonists
moving from extension into slight flexion - agonists are hamstrings and gastrocnemius
in mid stance where is the ankle and what is the agonist
continuing to move into plantar flexion - agonist is tricep surae
in late stance where is the hip and what are the agonists
in extension - agonists are gluteus Maximus and hamstrings
in late stance where is the knee and what muscles are contracting
in extension due to the position of the body - hamstrings and gastrocnemius are contracting ready for the next movement
in late stance where is the ankle and what is the agonist
in full plantar flexion - against is triceps surae (strong for propulsion)
in early swing where is the hip and what are the agonists and antagonists
in extension moving into flexion - agonists are iliopsoas and rectus femoris - antagonists and gluteus Maximus and hamstrings control rate of swing
in early swing where is the knee and what are the agonists
in flexion to lift foot from the ground - agonists are hamstring and gastrocnemius
in early swing where is the ankle and what is the agonist
in dorsiflexion to allow clearance of toes during swing - agonist is tibialis anterior
in mid swing where is the hip and what are the agonists and antagonists
in flexion - agonists are iliopsoas and rectus femoris - antagonists are gluteus Maximus and hamstrings control the rate of swing
in mid swing where is the knee and what are the agonists
in flexion to lift foot from the ground - agonists are hamstrings and gastrocnemius
in mid swing where is the ankle and what is the agonist
in dorsiflexion to allow clearance of toes during swing - agonist is tibialis anterior
in late swing where is the hip and what are the agonists
in flexion - agonists are iliopsoas and rectus femoris
in late swing where is the knee and what is the agonist
moving from flexion into extension to prepare for heel strike - agonist is quadriceps femoris
in late swing where is the ankle and what is the agonist and stabiliser
in dorsiflexion for most stable joint position for heel strike - agonist is tibialis anterior to pull into dorsiflexion - stabiliser is triceps surae to keep ankle stable
