Considerable controversy exists around the benefit of gait analysis in planning the treatment of disorders of gait. I have to admit that I am a firm advocate.
A big problem with gait analysis is that a good understanding of the underlying technology is needed so that the clinician is not led into false assumptions about the data provided. Even where the data is correct, the art comes in when a decision has to be made as to what to do.
Different treatment centres in different countries have differing views as to what is the correct treatment and the correct time for treatment.
