Gait is the way in which we move our whole body from one point to another. Most often, this is done by walking, although we may also run, skip, hop etc. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical. The technology supporting the analysis of human motion has advanced dramatically. Past decade of locomotion research have provided us with the significant knowledge about the accuracy of the test performed, the understanding of the process of human locomotion and how clinical test can be used to evaluate medical disorder and effect their treatment. Gait analysis is now recognized as clinically usefully and financially reimbursable for medical conditions. Yet, the route clinical use of gait analysis has been very limited growth. The issue of its clinical value is related to many factors, including the applicability of existing technology to addressing clinical problems, the limited use of such test to address a wide variety of medical disorder; the manner in which gait laboratories are organized ,test are performed and reports generated ;and clinical understanding and expectation of laboratories results. Clinical use is most mast hampered by the length of time and cost required for performing a study and interpreting it. A “gait” report is lengthy, its data are not well understood, and it includes a clinical interpretation, all of which do not occur with other clinical tests. Current biotechnology research is seeking to address these problems by creating techniques to capture data rapidly, accurately and efficiently and to interpret such data by an assortment of modeling, statically, wave interpretation and artificial intelligence methodologies. The success of such efforts rests on both our technical abilities and communication between engineers and clinicians.
