1

Normal distance for base of support

6-10 cm, measured between both heels

2

The time when only one foot is in contact with the floor

Single limb support

3

How much is the COG displaced horizontally and vertically during a normal step?

5cm horizontally and 5 cm vertically

4

5 phases of stance phase

I Like My Tea PREsweetened
1. Initial contact
2. Loading response
3. Midstance
4. Terminal stance
5. Preswing

5

What is considered a comfortable walking speed?

3 mph or 80m/min

6

During the gait cycle, how much %age is the swing phase and how much %age is the stance phase?

Stance = 60%
Swing = 40%

7

Where is the center of gravity typically located in relation to the S2 vertebra?

COG is 5 cm anterior to S2 vertebra

8

As walking speed increases, how does the stance phase and swing phase change?

Stance phase decreases and swing phase increases

9

What part of the gait cycle does the body have the lowest center of gravity?

The Loading Response

10

The time when both feet are in contact with the floor is known as

Double-limb support

11

Number of steps per unit time is known as...

Cadence

12

Stride length vs step length

Stride = heel strike of one foot to heel strike of the same foot
Step = heel strike of one foot to heel strike of the other foot

13

The gait cycle is made up of what 2 phases?

Stance phase and swing phase

14

What part of the gait cycle is COG the highest?

Midstance

15

What happens to time period of double limb support as walking speed increases?

Double limb support decreases

16

At midstance, where does the ground reactive force vector go in relation to the ankle, knee and hip?

Anterior to ankle
Anterior to knee
Posterior to hip

17

Normal step length

15-20 inches

18

What change in the gait cycle is a person considered running?

When there is no double limb support period

19

3 phases of swing phase?

In My Teapot
1. Initial swing
2. Midswing
3. Terminal swing
