Gait

• What are the key aspects of the gait cycle?

  • One step
  • Step length
  • Cadence
  • One stride
  • Touch-down (TD)
  • Toe-off (TO)
  • Stance phase (contact time)
  • Swing phase (flight time)
• What is gait?

  Fundamental movement patterns like walking and running
• What is a single gait cycle known as?

  Stride
• What begins a gait cycle?

  When the reference foot contacts the ground
• What ends a gait cycle?

  Subsequent floor contact of the same foot
• What is step length?

  Phase by one limb to the other limb's phase
• What is stride length?

  Distance between two placements of the same foot
• What is cadence?

  Number of steps per second
• What is speed in the context of gait?

  Distance covered by the body over one stride
• What does the stance phase represent?

  Support phase used for contact time
• What does the swing phase represent?

  Leg in the air
• What is the gait cycle for walking?

  • Starts with initial contact or heel strike
  • Ends with the following heel strike of the same foot
  • Stance phase is approx. 60% of the cycle
  • Double support/limb stance phase present
  • Swing phase is approx. 40% of the cycle
• What is the gait cycle for running?

  • Starts with initial contact or heel strike
  • Contact can occur with midfoot or forefoot
  • Ends with the following initial contact of the same foot
  • Has a flight phase
  • Stance phase is approx. 40% and swing approx. 60% of the cycle
• What are the key terms in force-time curves for walking?

  • Initial contact
  • Impact peak
  • Passive peak
  • Active peak
  • Midstance trough
  • Toe-off
  • Midstance
• What are the key terms in force-time curves for running?

  • Initial contact
  • Impact peak
  • Peak force
  • Propulsion phase
  • Braking phase
  • Toe-off
  • Midstance
• How does the stance phase differ between walking and running?

  Stance phase is approx. 60% in walking, 40% in running
• What is the difference in contact points during the gait cycle for walking?

  Contact can be heel, midfoot, or forefoot
