a! a! a! a! a! a! a! a! a! a! a! a! a! a! a!




✅ Optimal gait
a! a! a!




we want to take the pathological gait that is requiring a lot of energy expenditure and make it as close

Define Step Length -a! a! a! a!




✅ distance measured between right heel strike and left heel strike
a! a! a! a! a! a! a! a! a! a! a!




Define Step Width - a! a! a! a!




✅ side to side distance between similar points on both feet during two consecutive steps
a! a! a! a! a! a! a! a! a! a! a! a! a! a! a!

a! a! a! a! a! a! a! a! a! a! a! a! a!




Define line of progression -
a! a! a! a! a!




✅ The line of progression runs through the center between the left and right footprints. In normal gait
a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a!




the prints of the right foot lie to the right of this line and the prints of the left foot to the left. If both feet
a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a! a!
