So. How did you do?

As you can see, this individual lists to the R upon weight bearing on that side (midstance); did you pick up the increased progression angle of the foot on that side? How about the mild genu valgus?

Why would someone walk like this? There are a few plausible explanations.

1. he has a weak gluteus medius on the R side.

2. he has a R short leg and needs to lean to that side to get the long leg side (L) to clear.

3. impaired left ankle rocker (causing premature heel rise and left side early departure) could also cause him to accelerate onto the right as well.

His options to compensate are to either lean to the weak side ® or to shift his pelvis to the weak side ®. He could also circumduct the leg or flex the thigh to get that side to clear the ground. He has a mild BL circumdcution, probably to clear the knee from the opposite one.

His increased arm swing on the L is to help propel him forward, most likely due to weakness of the external obliques to assist in initiation of flexion of the thigh, and weakness of the gluteus medius, which also helps to propel the leg forward. He also does not push off adequately with the R leg; This is probably due to loss of hip extension and inadequate ankle rocker on that side.

The increased progression angle on the R helps to stabilize his body weight because he is leaning the torso to the R and his center of gravity moves right as well (he makes a wider base for himself)
