Gait characteristics

1. What is the stride length? Step length?
*2. What is the normal distribution between stance and swing phases?
3. What is the distribution between double limb and single limb support?
4. What is cadence?
5. What is a comfortable walking speed?
6. Where is the center of gravity?


Answers:
1. Stride is measured from successive points of contact of same foot. Step length is measured from points of contact of opposite feet (approx 15-20 in).
2. 60% in stance phase, 40% swing phase. Faster walking decreases time in stance phase.
3. Double support is 20% of gait cycle, single support is 80%.
4. Cadance is the number of steps per unit of time.
5. 3 MPH.
6. 5 cm anterior to the 2nd sacral vertebra.
