9.3 Gait Spatial and Temporal Characteristics

Question 1

What are spatial characteristics of gait?

Answer 1

Variables that describe distance or space, such as step length, stride length, step width, and angle of progression.

Question 2

What are temporal characteristics of gait?

Answer 2

Variables that describe time, such as walking speed, step duration, and cadence.

Question 3

What is stride length?

Answer 3

The distance between two successive heel strikes of the same foot.

Question 4

How long does one gait cycle or stride last at normal walking speed?

Answer 4

About 1 second.

Question 5

What is the average stride length for an adult?

Answer 5

Approximately 1.4 meters (144 cm).

Question 6

Is stride length always twice the step length?

Answer 6

Not always—variations in gait can make the relationship slightly different.

Question 7

What is step length?

Answer 7

The distance between heel strikes of opposite feet (e.g., right heel contact to left heel contact).

Question 8

What is the average adult step length?

Answer 8

About 72 centimeters.

Question 9

What is step width?

Answer 9

The distance between the midpoints of the heels of both feet.

Question 10

What is the normal range for adult step width?

Answer 10

About 2–4 inches (5–10 cm).

Question 11

When might step width increase?

Answer 11

In children or older adults, often due to balance or stability differences.

Question 12

What is the angle of progression?

Answer 12

The angle between the line of progression and a line through the foot (between the 2nd and 3rd toes), representing “toe-out.”

Question 13

What is the average angle of progression (toe-out) in adults?

Answer 13

About 7 degrees.

Question 14

How does the angle of progression change with speed?

Answer 14

It usually decreases as walking speed increases.

Question 15

What is gait speed (or velocity)?

Answer 15

The distance covered over a unit of time (e.g., meters per second or miles per hour).

Question 16

Why is gait speed important in gait analysis?

Answer 16

It affects time, distance, energy expenditure, and muscle activity during walking.

Question 17

What determines an individual’s free or comfortable walking speed?

Answer 17

It is the speed that is most energy-efficient for that person, influenced by stride length and leg length.

Question 18

How does gait cycle duration change with speed?

Answer 18

As speed increases, all gait cycle components (stance, swing, double support) shorten.

Question 19

What happens to double-limb support as walking speed increases?

Answer 19

It decreases and approaches zero during running.

Question 20

What happens to stance and double support when walking speed slows?

Answer 20

Stance time and double support time increase, while swing time remains relatively constant.

Question 21

What is the minimum safe community walking speed?

Answer 21

About 30 meters per minute (needed to safely cross a street).

Question 22

What walking distance is considered functional for community ambulation?

Answer 22

Approximately 342 meters (e.g., from a parking lot through a store and back).

Question 23

What is the average adult gait speed?

Answer 23

About 82 meters per minute (≈3 miles per hour).

Question 24

What is cadence?

Answer 24

The number of steps per minute (step rate).

Question 25

What is the average adult cadence?

Answer 25

About 113 steps per minute.

Question 26

What is stride time?

Answer 26

The time it takes to complete one stride—about 1 second.

Question 27

What is step time?

Answer 27

The time it takes to complete one step.
