Some aspects of modern orthotics.

Orthotics is changing more rapidly than ever before, largely resulting from improved understanding of the human requirements and the current state of technological abilities. Walking is always seen as a basic requirement for normal activity and as such it is in this area that most research and development effort is expended. This paper outlines some of the current developments in this interesting topic and includes seating and posture as these are often viewed as precursors to successful standing and then, possibly, gait.
