gait cycle

Question 1

gait cycle

Answer 1

the time period or sequence of events or movements locomotion in which one foot contacts the ground to when that same foot again contacts the ground

Question 2

heel strike

Answer 2

(1) the limb just swung forward, now it hits the ground heel first; the gluteus maximus is acting eccentrically to decelerate hip flexion; the anterior compartment of the leg is contracting the dorsiflexion foot

Question 3

foot flat

Answer 3

(2) the toes are lowered to the ground, anterior compartment of the limb contacts eccentrically to absorb the force; knee flexes slightly; gluteal muscles balance the body weight over planted limb; quadriceps femoris muscles contract eccentrically to prevent knee from buckling

Question 4

midstance

Answer 4

(3) the limb is perpendicular to the ground and hip is extended; “hamstrings” (posterior compartment of thigh) extend thigh; quadriceps femoris extend the leg; posterior compartment of leg continues to propel the step by producing plantarflexion of the foot

Question 5

heel off

Answer 5

(4) hip and knee are extended; foot is plantarflexes; heal leaves ground; the posterior compartment of the leg plantarflexes the foot

Question 6

toe off

Answer 6

(5) as the toes kick off, the knee flexes; the hamstrings flex the knee; deep muscles of the posterior compartment of the leg plantarflex the toes

Question 7

swing phase

Answer 7

(6) marked by flexion of the thigh, knee is flexed and foot is dorsiflexed to clear the ground; rectus femoris and iliopsoas flexors of the thigh power the phase; hamstrings and anterior compartment of leg control knee and foot flexion

Question 8

late swing phase

Answer 8

(7) the hip is flexed; the knee is extended; the foot is dorsiflexed; limb prepares for heel strike
