1

gait cycle: average step length

14-16 inch

2

gait cycle: average cadence

90-120 steps/ min (higher by 6 in women)

3

gait cycle: average speed

3 mph

4

gait cycle: definition

from heel strike to heel strike of the same foot

5

gait cycle: 2 phases

stance and swing

6

gait cycle: positions

heel strike --> foot flat --> heel off --> toe off -->heel strike

7

gait cycle: "swing" phase occurs in between which foot positions

toe off to heel strike

8

gait cycle: "propulsion" is made of which 2 foot positions

heel off and toe off

9

whats the name for the foot joint connecting the 5 metatarsals to the distal most tarsal bones

lisfranc joint

10

whats the name for the foot joint connecting hind foot (calcareous and talus) to mid foot structures (cuneiforms, cuboid, and navicular)

midtarsal (chopart) joint

11

mm responsible for lowering foot to ground for "contact" phase of gait cycle

extensor digitorum longus, tibialis anterior

12

what must the tibia do after heel strike in order for calcaneus to evert and talus to drop (which unlocks mid tarsal joints for shock absorption)

internally rotate

13

during mid stance, the body's center of gravity shifts where

from behind to over the foot

14

as the body passes over mid-foot, it places ankle in maximal dorsiflexion. this puts maximal preload on what mm

gastroc-soleus complex

15

whats the term for the effect that occurs when 1st metatarsophalangeal joint extends resulting in plantar fascia that elevates the arch and further assists in foot supination

windlass effect

16

most problems with gait cycle occur during which phase

stance phase

17

which part of gait cycle is also called initial contact

heel strike

18

which part of gait cycle is also called loading response

foot flat

19

which part of gait cycle is also called terminal stance

heel off

20

which part of gait cycle is also called pre swing

toe off (50-60% of the stance cycle is spent here)

21

when the left foot is in mid stance where is the right foot

mid swing

22

when the left foot is in initial contact where is the right foot

terminal stance

23

which gait cycle phase provides limb and trunk stability

mid stance

24

which gait cycle phase provides weight release from stationary foot

pre swing

25

we have single limb support for how much of our gait cycle

80%

26

how much does your center of gravity move in a superior/ inferior motion during gait cycle

less than 2 in

27

how does our center of gravity shift superior/ inferior during gait cycle

early stance: weight transferred to foot. the hip on the non weight bearing side drops 2 in

28

how do we "lengthen" the femur during gait cycle

innominate (pelvis) rotates anterior 4 ish degrees

29

which gait disturbance: adopted limp to avoid pain on weight bearing structures, short stance phase on affected side

antalgic gait

30

which gait disturbance: stiffness in affected joints, plantar flex opposite to affected side to increase clearance, affected leg is circumducted, step is shorter

arthrogenic gait
