Step Length

The linear distance from one heel strike to the next heel strike of the opposite foot.

Foot Angle

The angle between the line of progression and a line from the heel's center to the second toe.

Stride Width

The horizontal distance between the midpoints of both heels.

Cadence

The number of steps taken per minute.

Study Notes

Gait Analysis

  • Gait analysis involves kinematics, kinetics, distance and time variables, external forces, measurement of joint angles, internal forces, and determinants of gait.

Distance Variables

  • Step length: linear distance from right heel to successive left heel, approximately 70.5 cm
  • Stride length: linear distance from right heel to successive right heel, approximately 141 cm
  • Stride width: horizontal distance between midpoint of one heel to another heel, approximately 8 cm (range: 2.5-12.5 cm)
  • Foot angle (degree of toe out): angle between line of progression and line passing from center of heel to 2nd toe, approximately 7-10°

Time Variables

  • Cadence: number of steps per minute, approximately 113 steps/min
  • Speed: distance covered per unit time, approximately 1.2 m/sec (or 82 m/min)
  • Step, stride, stance, swing, single limb, and double limb are all related to time variables

Calculations

  • Cadence = Number of steps / minute
  • Speed = Distance covered / time
  • Stride time = GC time = 0.8 sec
  • Swing time = 0.8 - 0.3 = 0.5 sec
  • Float period = 0.5 * 20/100 = 0.1 sec
