The concept of body schema has been introduced and widely discussed in the
literature to explain various clinical observations and distortions in the body
and space representation. Here we address the role of body schema related
information in multi-joint limb motion. The processing of proprioceptive
information may differ significantly in static and dynamic conditions since in
the latter case the control system may employ specific dynamic rules and
constraints. Accordingly, the perception of movement, e.g., estimation of step
length and walking distance, may rely on a priori knowledge about intrinsic
dynamics of limb segment motion and inherent relationships between gait
parameters and body proportions. The findings are discussed in the general
framework of space and body movement representation and suggest the existence of
a dynamic locomotor body schema used for controlling step length and path
estimation.
