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.
Since 1689 gait analysis has been started, Aristotle as pioneer which make book about gait in animals (De Motu Animalium). But Modern gait analysis begun in early 1900s. They are Eadweard Muybridge and Etienne-Jules Marey who being pioneer modern gait analysis. They are developed some equipments to records gait movements without the naked eyes but used camera to capture image of subject during gait movement.
Gait parameter usually obtained to collecting normal human gait database. This is parameter which used for gait analysis:
Lower limb joint angle.
Gait analysis has applicable for daily activity and also being important aspect for human movement analysis, for example gait analysis used for comparing between normal subject with abnormal subject who have movement disorder such as stroke, cerebral palsy and so on.
Generally the gait analysis applicable for aspects as follows:
a. Medical Diagnostics.
b. Biometric Identification.
c. Comparative Biomechanics
For the future developing gait analysis system is requirements for each countries in the world, because for each country will have different gait parameter for normal subject. This will being the big challenging for young researcher to develope the gait system with affordable.
