Artho and Osteokinematics
The glide of the talocrural joint in closed-chain plantarflexion
What is posterior glide
The primary shock-absorbing arch of the foot
What is the medial longitudinal arch?
The primary muscle(s) for plantarflexion
What is gastrocsoleus (or triceps surae)
The foot rocker associated with pre-swing
What is the toe rocker?
The percentage of time in stance and time in swing during the gait cycle
What is 60% and 40%
The glide of the talocrural joint in open-chain dorsiflexion
What is posterior?
The deep ligament that directly supports the head of the talus
What is the calcaneonavicular (spring) ligament?
The muscle in the lower leg that is constantly activated during quiet stance
What is soleus?
The position of the talocrural joint at initial contact
What is neutral?
One of the double limb support phases
What is IC/loading response or pre-swing?
The direction a PT would glide the phalanx of the great toe to improve extension (dorsally or plantarly)
What is dorsally?
What is the plantar fascia (or plantar aponeurosis)
The muscle responsible for stabilizing the first metatarsal as GRF attempts to dorsiflex it
What is peroneus longus?
The end of the initial swing phase
What is when the feet are adjacent or next to each other?
The muscle that helps the swing leg maintain forward momentum during initial and mid swing
What is the iliopsoas?
The relative talocrural osteokinematic movement during stand to sit
What is dorsiflexion?
The open chain components of all 3 planes of motion for supination
What is inversion, adduction, and plantarflexion?
The muscle and activation that helps control pronation during stance
What is tibialis posterior?
The phase when the majority of power is produced for gait
What is pre-swing?
Type of muscle activation that is associated with energy absorption
What is eccentric?
The triplanar position of the foot at initial contact essential for adapting to uneven surfaces
What is pronation?
The action that occurs in the forefoot when weight is shifted onto the supinating foot
What is pronation twist?
The muscles that originate within the foot and insert on the foot
What are the intrinsic muscles?
One of the primary objectives of the loading response phase
What are shock absorption, weight bearing stability, and preservation of progression
Sagittal plane motion occurring in the pelvis during gait
What is anterior and posterior pelvic tilt?
