Complex movement and Gait Flashcards
True or false, gait appearance is characteristic to each person
true
Early stance: describe the Hip joint
Flexed but moving into extension, Gluteus maximus and Hamstrings (Biceps femoris, semitendinosus, semimembranosus) contracting to move hip back wards
Early stance: describe the knee joint
fully extended due to the movement of the person, this provides the most stability for when leg hits ground, the quadriceps femoris and the hamstrings and gastrocnemius are acting isometrically to keep it this way
Early stance: describe the Ankle joint
Ankle: In full dorsiflexion as that is the most stable way to land, as it has the most bony congruence. moving into plantarflexion due to concentric activity of triceps surae, eccentric tibialis anterior activity controls the rate foot drops.
Mid stance: describe the Hip joint
Hip: moving into extension, Gluteus maximus and Hamstrings (Biceps femoris, semitendinosus, semimembranosus) contracting to move hip back ward
Mid stance: describe the knee joint
Knee: knee is in slight flexion, the hamstrings and gastrocnemius are contracting
mid stance: describe ankle joint
Ankle: moving into plantar flexion, the triceps surae ( gastrocnemius and soleus) are contracting
Late stance: describe Hip joint
Hip: Full extension, Gluteus maximus and Hamstrings (Biceps femoris, semitendinosus, semimembranosus) contracting to move hip backwards
Late stance: describe knee joint
Knee: in extension as this provides the most propulsion of the leg forward, the knee is fully extended due to the plantar flexion of the ankle. But the hamstrings and gastrocnemius are contracted as knee flexes when the toe is off
Late stance: describe ankle joint
Ankle: in full plantarflexion, as this provides the best forward thrust for leg swing, the triceps surae are contracted.
What can late stance also be called
toe off
what can early stance also be called
heel strike
early swing: describe hip joint
Hip: In extension but beginning to flex. Iliopsoas acting concentrically. Gluteus maximus and Hamstrings( biceps femoris, Semimembranosus and Semitendinosus) acting eccentrically to control the rate the hip swings forward.
Early swing: describe the knee joint
Knee: knee is in flexion so hamstrings and gastrocnemius are contracted.
Early swing: describe the ankle joint
Ankle: in plantarflexion but moving into dorsiflexion( so the foot can clear ground as swings through) thus the tibialis anterior is contracting
