Begin by looking at the soles of the clients shoes – this will give you a good idea of weight distribution during gait.
Gait should be observed both with shoes on and shoes removed.
With the shoes removed take note of the structure of the foot and ankle – note and deformities.
Observing gait you should watch how the entire body moves together. Look at stride length, are they even? Look at hip movement, arm swing, shoulder position, head posture.
