For over 20 years gait analysis has been a useful clinical tool in the management of walking and movement problems1. Technology and our understanding of its role in clinical application have improved significantly in recent years. This has allowed for gait analysis to evolved into a recognized medical procedure that is necessary for the planning of surgery or other therapeutic interventions in the management of spasticity and in the prescription and optimization of orthotic and prosthetic devices and the most important contribution as a quantitative assessment tool for movement in general and walking specifically. The ability to perform a meaningful interpretation of the large and complex data remains a challenge for many physicians. A clear understanding of the data and the ability to perform a meaningful interpretation that is clinically applicable and its relationship to impairment, disability and handicap remains a challenge for many physicians. This requires that the clinician be familiar with the complex physiological interactions of normal gait and movement biomechanics, functional anatomy, normal and abnormal patterns of motor control and with the technology used for its assessment.
