Gait Cycle - Exercises Flashcards
What is the longest phase of gait cycle?
Mid stance
At which stage do the quads have an important eccentric action?
Loading Response - Weight acceptance. Knee flexes as a response to the weight acceptance that is controlled by a eccentric contraction of the quads.
Where is it possible to find maximal value of ankle dorsi flexion?
Late terminal stance.
Ankle static in mid swing.
Where is it possible to find maximal value of plantar flexion?
Final moment of pre-swing.
Which combination of movements represent the mechanism of foot clearance?
Ankle dorsi flexion, knee flexion, hip flexion.
What you do in the initial swing, makes sure you have enough space between foot and ground.
In terminal swing, which muscle is working and how do you control the knee joint?
Hamstrings, eccentric to control the movement of knee extension.
During initial contact, which muscle is mainly responsible for propulsion?
Gluteus maximus (primary hip extensor)
Concentric.
Gluteus medius stabilizes pelvis/hip in single support, from initial contact to terminal stance.
Which muscle is active in the hip joint, during terminal stance?
Hip extension during terminal stance.
Adductor Longus, provides stability on sagittal and frontal plane. Eccentric contraction.
Where does the third foot rocker have it’s center of motion?
Metatarsalphalangeal joints. Articulation is extending, closed kinetic extension.
Which muscle is active around the knee joint in terminal stance?
At the knee, gastrocnemius is holding the knee in full extension.
Which muscle is not active during the initial swing phase? A) Semitendinosus B) Tibialis anterior C) flexor digitorum longus D) sartorius
Dorsi flexion, knee flexion, hip flexion.
Flexor digitorum longus is not active.
Semitendinosus, tibialis anterior and sartorius are all active.
