1

gait cycle

- from initial heel contact of one foot to heel contact of the same foot
- aka stride
- has 2 steps

2

stride length

- distance between 2 successive heel contacts of the same foot
- normal - 1.51 m for males and 1.32 for females

3

step length

Distance between successive heel contacts of 2 different feet

4

Degree of toe-out

- Angle between line of progression of the body and a line intersecting the center of the heel and second toe
- normal - 5-7 degrees

5

step width

- Lateral distance between heel centers of 2 consecutive foot contacts
- average is 7-10 cm

6

stride time

Time for a full gait cycle

7

step time

Time for completion of a R or a L step

8

cadence

- aka step rate
- # of steps per minute
- normal - 108 steps/min for males and 118 steps/min for females

9

walking speed

- Distance covered in a given amount of time
- normal - 1.37 m/sec for males and 1.30 m/sec for females
