Osteokinematic/Arthrokinematic Motions Flashcards
What are the 4 osteokinematic motions of the spine?
Flexion, extension, rotation, and lateral flexion
Lumbar flexion is an (anterior/posterior) and (superior/inferior) glide.
anterior and superior
What is the main muscle we talked about in class that works to flex the lumbar spine?
The rectus abdominus
Lumbar extension is a (anterior/posterior) and (superior/inferior) glide.
posterior and inferior
What is the main muscle group we talked about in class that work to extend the lumbar spine?
The erector spinae
If the lumbar spine tries to rotate to the right, the (right/left) articular facet will come under compression and limit this motion.
left
What muscles work to rotate the spine?
The internal and external obliques
In left lateral flexion, the right articular facet is going to slide in a (infero-medial/supero-lateral) direction and the left articular facet is going to slide in a (infero-medial/supero-lateral) direction.
supero-lateral; infero-medial
What muscles laterally flex the lumbar spine?
The quadratus lumborum and intertransversarii muscles
What are the normal osteokinematic motions that occur at the knee?
Flexion and extension
During knee flexion and extension, the tibia is (concave/convex) and the femur is (concave/convex).
concave; convex
Open chain knee flexion/extension is (concave on convex/convex on concave).
concave on convex
Closed chain knee flexion/extension is (concave on convex/convex on concave).
convex on concave
What is the arthrokinematics of open chain knee flexion?
Posterior roll and slide
What is the arthrokinematics of open chain knee extension?
anterior roll and slide
What is the arthrokinematics of closed chain knee flexion?
Posterior roll and anterior slide
What is the arthrokinematics of closed chain knee extension?
Anterior roll and posterior slide
What muscles work to flex the knee?
The hamstrings, gastrocnemius, and popliteus
What muscles extend the knee?
The quadriceps femoris
What are the osteokinematic motions at the hip?
Flexion/extension, adduction/abduction, and internal/external rotation
What are the arthrokinematic motions for every motion at the hip?
A spin
What muscle group and separate muscle flex the hip?
The quadriceps femoris and the iliopsoas
What muscles extend the hip?
The gluteus maximus and the hamstrings
What muscles adduct the hip?
Adductor longus, adductor magnus, adductor brevis, pectineus, and gracilis
What muscles abduct the hip?
Gluteus medius, gluteus minimus, and the tensor fasciae latae
What muscles medially rotate the hip?
Gluteus medius, gluteus minimus, and tensor fasciae latae
What muscles externally rotate the hip?
Gluteus maximus and the external rotator muscle group (piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus).
What are the osteokinematic motions that occur at the foot and ankle?
Dorsiflexion/plantarflexion, adduction/abduction, and inversion/eversion
For the arthrokinematic motions of the talocrual joint in open chain, the talus is moving on the tibia and fibula and the talus is (concave/convex) and the tibia and fibula are (concave/convex).
convex; concave
In the open kinetic chain in dorsi flexion, the talus rolls (anteriorly/posteriorly) and slides (anteriorly/posteriorly).
In the open kinetic chain in plantar flexion, the talus rolls (anteriorly/posteriorly) and slides (anteriorly/posteriorly).
anteriorly; posteriorly; posteriorly; anteriorly
For the arthrokinematic motions of the talocrual joint in the closed chain, the tibia and fibula is moving on the talus and the talus stays put. The tibia and fibula are (concave/convex) and the talus is (concave/convex).
concave; convex
In CKC dorsi flexion and plantar flexion it is (concave on convex/convex on concave).
In CKC dorsi flexion it is an (anterior/posterior) roll and (anterior/posterior) slide.
In the CKC for plantar flexion it is a (anterior/posterior) roll and (anterior/posterior) slide
concave on convex; anterior; anterior; posterior; posterior
What are the motions involved in open chain supination?
Adduction, plantar flexion, and inversion
What are the motions involved in open chain pronation?
Abduction, dorsiflexion, and eversion
What are the motions involved in closed chain supination?
calcaneal inversion, talar dorsiflexion, and abduction
What are the motions involved in closed chain pronation?
Calcaneal eversion, talar plantar flexion and adduction
What muscles dorsiflex the ankle?
Tibialis anterior, extensor hallucis longus, and extensor digitorum longus
What muscles plantar flex the ankle?
Gastrocnemius and soleus
What muscles invert the foot?
Tibialis anterior and tibialis posterior
What muscles evert the foot?
Fibularis longus and brevis
