(a) Infant in supine position using a Pavlik harness: the distal part of the leg can rotate and move on its own longitudinal axis, the foot sole can move along a plane transversal to the body, and the pelvis is fixed; (b) infant in supine position using a rigid splint: the pelvis is fixed and the leg can only move along the femoral longitudinal axis; (c) infant in standing position using a rigid splint: the pelvis can only move on the longitudinal axis of the body, the leg in the longitudinal femoral direction, and the foot sole has a planar restriction simulating the normal force exerted by the floor; (d) infant in standing position using a spica cast with the fixation bar at knee height: the pelvis can only move on the longitudinal axis of the body, the leg has been restricted to move only on a sagittal plane at knee height, and the foot sole has a planar restriction simulating the normal force of the floor; (e) infant in standing position using a spica cast with the fixation bar at ankle height: the pelvis can only move on the longitudinal axis of the body, the leg has been restricted to move only on a sagittal plane at ankle height, and the foot sole has a planar restriction simulating the normal force of the floor; and (f) infant with no orthopedic treatment: the pelvis can only move on the longitudinal axis of the body and the foot sole has a planar restriction simulating the normal force of the floor.
