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:
Step length
Stride length
Cadence
Speed
Dynamic Base
Progression line
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.
