Study Notes

  • Walking is a cyclic series of movements characterized by a gait cycle.
  • The gait cycle starts with heel contact and ends with the same foot making contact with the ground again.
  • A stride is the sequence of events between successive heel contacts of the same foot.
  • A step is the sequence of events within successive heel contacts of opposite feet.
  • A gait cycle has two steps - left and right.
  • Stride length is the distance between two successive heel contacts of the same foot.
  • Step length is the distance between successive heel contacts of the two different feet.
  • Step width is the lateral distance between the heel centers of two consecutive foot contacts.
  • Foot angle is the angle between the line of progression of the body and the long axis of the foot.
  • The norms for step width and foot angle are relatively similar in healthy young adults and children aged 7 to 12 years.
