Gait I & II

Question 1

Stride

Answer 1

Time between when one foot touches the floor and when the same foot touches the floor again

Question 2

Stride length

Answer 2

Distance in gait cycle

Question 3

Step

Answer 3

One half of a stride

Question 4

Step length

Answer 4

Distance between heel strike of. One foot and heel strike of other floor (should be equal)

Question 5

Cadence

Answer 5

Walking speed

Question 6

Stance phase

Answer 6

Activity when the foot is in contact with the ground

- 60% of gait cycle

Question 7

Swing phase

Answer 7

Activity when the foot is not in contact with the ground

- 40% of gait cycle

Question 8

Weight acceptance

Answer 8

When foot touches ground and body weight starts to shift onto that leg
- early in stance phase

Question 9

Leg advancement

Answer 9

When the leg opposite the stance leg swings forward

- swing phase

Question 10

Single support

Answer 10

Period when only one foot is in contact with the ground

Question 11

Double support

Answer 11

Period when both feet are in contact with the ground at the same time

Question 12

Stance phase of gait (list both traditional and ranchos los amigos)

Answer 12

1. Heel strike — initial contact
2. Foot flat — loading response
3. Medstance — midstance
4. Heel-off — terminal stance
5. Toe-off — preswing

Question 13

Swing phase of gait (list both traditional and ranchos los amigos)

Answer 13

1. Acceleration — initial swing
2. Mid swing — midswing
3. Deceleration — terminal swing

Question 14

Vertical displacement

Answer 14

Normal raising and lowering of the COG during gait

- approx. 2 inches (highest at midstance and lowest at heel strike or initial contact)

Question 15

Horizontal displacement

Answer 15

Normal lateral shifting of COG during gait as body weight shifts from side to side
- approx 2 inches (greatest during midstance)

Question 16

Initial contact

Answer 16

Heel strike

• beginning of stance phase, weight acceptance begins, double leg support beings
• begin: when heel contacts ground
• end: at beginning of loading response

Question 17

Loading response

Answer 17

Foot flat

• end of double leg support
• begin: weight shifted on to the limb and entire foot makes contact w/ground
• end: when opposite foot leaves the ground

Question 18

Midstance

Answer 18

Midstance

• single leg support begins
• begin: opposite foot leaves the ground
• end: when body is directly over WB limb

Question 19

Termal stance

Answer 19

Heel off

• body passes beyond stance leg, single limb support ends (double limb support starts)
• begin: as heel of WB limb rises
• end: at initial contact of opposite foot

Question 20

Preswing

Answer 20

Toe off

• brief time of double limb support
• begin: initial contact of opposite leg and when weight is shifted onto opposite leg
• end: just before the toes of WB limb leave the ground

Question 21

Initial swing

Answer 21

Acceleration

• beginning of swing phase
• begin: toes leave ground
• end: when swing foot is opposite the WB foot and the knee is in max flexion

Question 22

Midswing

Answer 22

Midswing

• max knee flexion for clearance required
• begin: when swing foot is opposite WB foot
• end: swing leg is in front of body w/ tibia vertical to ground

Question 23

Terminal swing

Answer 23

Deceleration

• single lime support ends
• begin: when tibia is vertical to ground
• end: just prior to initial contact
