Gait analysis is the systematic study of animal locomotion, more specifically the study of human motion, using the eye and the brain of observers, augmented by instrumentation for measuring body movements, body mechanics, and the activity of the muscles.〔Levine DF, Richards J, Whittle M. (2012). Whittle's Gait Analysis (Whittle's Gait Analysis ) Elsevier Health Sciences. ISBN 978-0702042652〕 Gait analysis is used to assess, plan, and treat individuals with conditions affecting their ability to walk. It is also commonly used in sports biomechanics to help athletes run more efficiently and to identify posture-related or movement-related problems in people with injuries. The study encompasses quantification, (i.e., introduction and analysis of measurable parameters of gaits), as well as interpretation, i.e., drawing various conclusions about the animal (health, age, size, weight, speed etc.) from its gait pattern. ==History== The pioneers of scientific gait analysis were Aristotle in ''De Motu Animalium'' (On the Gait of Animals) and much later in 1680, Giovanni Alfonso Borelli also called ''De Motu Animalium (I et II)''. In the 1890s, the German anatomist Christian Wilhelm Braune and Otto Fischer published a series of papers on the biomechanics of human gait under loaded and unloaded conditions. With the development of photography and cinematography, it became possible to capture image sequences that reveal details of human and animal locomotion that were not noticeable by watching the movement with the naked eye. Eadweard Muybridge and Étienne-Jules Marey were pioneers of these developments in the early 1900s. For example, serial photography first revealed the detailed sequence of the horse "gallop", which was usually misrepresented in paintings made prior to this discovery. Although much early research was done using film cameras, the widespread application of gait analysis to humans with pathological conditions such as cerebral palsy, Parkinson's disease, and neuromuscular disorders, began in the 1970s with the availability of video camera systems that could produce detailed studies of individual patients within realistic cost and time constraints. The development of treatment regimes, often involving orthopaedic surgery, based on gait analysis results, advanced significantly in the 1980s. Many leading orthopaedic hospitals worldwide now have gait labs that are routinely used to design treatment plans and for follow-up monitoring. Development of modern computer based systems occurred independently during the late 1970s and early 1980s in several hospital based research labs, some through collaborations with the aerospace industry.〔Sutherland, DH. (2002). The evolution of clinical gait analysis: Part II Kinematics ''Gait & Posture''. 16: 159-179.〕 Commercial development soon followed with the emergence of commercial television and later infrared camera systems in the mid-1980s. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「gait analysis」の詳細全文を読む スポンサード リンク
