Gait Cycle

1

Phase of Gate cycle

• Stance Phase (%60)• Swing Phase (%40)• Single support (%80)• Double support (20%)

Event of Stance Phase

4

• Heel contact or Heel strike• heel of the leading extremity strikes the ground• In abnormal gait, toe or whole foot may come to

contact (initial contact)

• Foot flat • when the foot is flat on the ground (about 7% of gait

cycle

• Mid stance• body weight is directly over foot extremity (30% of

gait cycle)

• Heel off• heel leaves the ground (about 40% of the gait cycle).

• Toe of• the toe leaves the ground (about 60% of the gait

cycle.

Subphases of Stance Phase

1- Heel strike phase (T) • begins with initial contact and ends with

foot flat and occupies only a small percentage of the gait cycle

2-Loading response (RLA)• begins at initial contact and ends when

the contralateral limb lifts off the ground at the end of the double-support (11% of the gait cycle)

10

4- Terminal stance (RLA)• begins when the body is directly over

the supporting limb at about 30% of the gait cycle and ends a point just before initial contact of the contralateral extremity at about 50% of the gait cycle.

5- Push-off phase (T) • begins with heel-off at about 40% of

the gait cycle and ends with toe-off at about 60% of the gait cycle

11

Subphases of Stance Phase

6-Preswing (RLA) • is the last 10% of stance phase and

begins with initial contact of the contralateral foot (at 50% of the gait cycle) and ends with toe-off (at 60%).

12

Subphases of Stance Phase

3- Midstance phase (T) • (T) begins with foot flat at 7% of the

gait cycle and ends with heel-off at about 40% of the gait cycle. Midstance phase

• (RLA) begins when the contralateral extremity lifts off the ground at about 11% of the gait cycle and ends when the body is directly over the supporting limb at about 30% of the gait cycle, Smaller compared to T
