Phases Of Gait Cycle

Front 1

Describe Initial Contact

Back 1

Foot of the lead extremity strikes the ground.

Front 2

Describe Loading Response

Back 2

Begins with Initial contact until the contralateral limb is lifted for swing.

Front 3

First period of Double Support

Back 3

Loading Response

Front 4

Describe Midstance

Back 4

Begins at the end Loading Response as the contralateral foot is lifted from the ground and continues until the body weight is aligned over the forefoot and Tibia of swing leg approaches vertical.

Front 5

Describe Terminal Stance

Back 5

Begins with heel rise and continues until the contralateral foot strikes the ground

Front 6

Period(s) of Single limb support

Back 6

Midstance
Terminal swing

Front 7

Describe Pre-Swing

Back 7

Begins with Initial contact of the contralateral limb and ends with ipsilateral toe-off

Front 8

Traditional terminology: Point when the heel of the reference of support limb touches the ground

Back 8

Heel Strike

Front 9

Traditional terminology: The point when the sole of the foot of the reference limb makes contact with the ground

Back 9

Foot flat

Front 10

Traditional terminology: The point at which full body weight is taken by the reference for support limb

Back 10

Midstance

Front 11

Traditional terminology: The heel of the reference or support limb leaves the ground.

Back 11

Heel-off

Front 12

Traditional terminology: Only the toe of the reference or support limb is in contact with the ground

Back 12

Toe-off

Front 13

Muscle(s) active during Initial Contact

Back 13

Knee extensors
Ankle dorsiflexors

Front 14

Muscle(s) active during Loading response

Back 14

Knee extensors
Anke PF (Gastrocnemius-Soleus)

Front 15

Muscle(s) active during Midstance

Back 15

Hip, knee, and ankle extensors
Hip abductors

Front 16

Muscle(s) active during terminal stance

Back 16

Ankle PF

Front 17

Muscle(s) active during Pre-swing

Back 17

Hip and knee extensors (hamstring and quads)

Front 18

Describe Initial Swing

Back 18

Starts from toe-off of the reference limb to maximum knee flexion of the same extremity

Front 19

Describe midswing

Back 19

Starts from maximum knee flexion of the reference limb to a vertical tibial position

Front 20

Describe Terminal swing

Back 20

Starts from vertical tibial position of the reference limb to just prior to Initial contact

Front 21

Traditional termnology: Starts from toe-off of the reference limb until midswing

Back 21

Acceleration

Front 22

Traditional termnology: The reference extremity moves directly below the body

Back 22

Midswing

Front 23

Traditional termnology: The reference extremity is slowing down inpreparation for heel strike

Back 23

Deceleration

Front 24

Muscle(s) active during Initial Swing

Back 24

Quadriceps
Hip flexors (Iliopsoas)

Front 25

Muscle(s) active during Midswing

Back 25

Hip, knee flexors
Ankle DF

Front 26

Muscle(s) active during Terminal Swing

Back 26

Hamstrings
Quadriceps
Ankle DF
