Gait

Question 1

Stride length

Answer 1

1 gait cycle

Question 2

step length

Answer 2

1 limb until step with next limb

Question 3

ROM at hip needed for normal gait

Answer 3

stance phase: 0-30flexion, 0-10-20 hyperextension
swing phase: 20-30flexion

Question 4

ROM at knee needed for normal gait

Answer 4

stance phase: 0-40deg flexion
swing phase: 0-60deg flexion

Question 5

rom at ankle needed for normal gait

Answer 5

stance phase: 0-10deg DF, 0-20deg PF
swing phase: 0-10deg PF

Question 6

pretibial mm in gait cycle

Answer 6

prior to and during heel strike: eccentric contraction - lowers foot to ground
prior to and during swing:
concentric contraction - DF, clear toes off ground

Question 7

calf mm in gait cycle

Answer 7

mid stance: eccentric contraction - control of tibia over foot
heel off: concentric contraction - ankle PF

Question 8

Quad mm in gait cycle

Answer 8

heel strike: QF contracts eccentrically - control rapid knee flexion and to prevent buckling
pre-swing phase - eccentric contraction - slow down leg (tibia)

Question 9

hamstring mm in gait cycle

Answer 9

before heel strike: eccentric - protects knee from hyperextension
swing phase: concentric - knee flexion, hip extension

Question 10

hip abductors in gait cycle

Answer 10

stance phase: eccentric - stabilize pelvis

Question 11

hip adductors in gait cycle

Answer 11

early and late stance: concentric contraction - stabilize pelvice

Question 12

gluteus maximus in gait cycle

Answer 12

stance phase: eccentric contraction - decelerate forward momentum
pre-swing phase: concentric contraction - hip extension

Question 13

erector spinae in gait phase

Answer 13

heel strike through toe off
maintain trunk posture

Question 14

peroneus longus and brevis during gait cycle

Answer 14

stance phase: concentric - maintain medial and lateral stability of foot

Question 15

foot intrinsics during gait cycle

Answer 15

stance phase: concentric - support plantar fascia

Question 16

which way does trunk lean during stance with weak mm?

Answer 16

trunk is magnet to weak mm during stance: goes toward

Question 17

Which way does trunk lean during swing with weak mm

Answer 17

trunk goes opposite of weak mm during swing to propel: goes away

Question 18

what can cause delayed heel contact?

Answer 18

weak DFs

Question 19

which side to hold briefcase?

Answer 19

with wheels: opposite side
without wheels: same side
