Phase of Gate cycle
• Stance Phase (%60)• Swing Phase (%40)• Single support (%80)• Double support (20%)
2
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
