Gait analysis measurement is a method to access and identify gait events and the
measurements of dynamic and motion parameters involving the lower part of body. This
significant method is widely used in sports, rehabilitation as well as the health
diagnostic towards improving the quality of life. Many researchers has proposed various
ways to access gait features that require specially set-up motion laboratories, high-end
video based-motion imaging systems, and professionals to visually observe the gait, this
makes current way of accessing gait to be very costly and limited in many ways.
Therefore, this research focuses on design and development of a portable shoe
integrated wireless MEMS-based and recent microelectronic based foot clearance
measurement system that is cheap, portable, real life and can be used by more people.
The foot clearance measurement is representing the measurement of the distance
between foot and ground. A complete system called Portable Shoe Integrated
Instrumentation for Gait Analysis Measurement Using MEMS Based Devices in realtime
is proposed. This system is the combination of the ultrasonic sensor with the
inertial measurement unit sensor. The ultrasonic sensor is used for clearance
measurement and the inertial measurement unit sensor is used for orientation
measurement. Based on the orientation measurement, the clearance measurement is
corrected by trigonometry algorithm. The correction is due to the positioning of foot
during landing phase and toe off phase. In both situations, the positioning of ultrasonic
is not perpendicular to the ground. So, the algorithm is required to present the accurate
data. This system comes with the custom design software called Gait Analysis Software
to analyze and present the gait information of user based on gait parameters which
include foot clearance and foot orientation. Thus, this research produces three custom
made systems namely GAS-US System, GAS-IMU System and GAS-COM System.
Each system has its own purpose. The system was tested and proven to satisfy the gait
analysis requirement. From this research, it is found that the system is able to measure
the gait parameter wirelessly with ease and efficiently. Hence, to conclude this system
can be used as the best method for real life gait analysis measurement. The novelty of
this research is the first design combination of ultrasonic sensor with the initial
measurement unit sensor for foot clearance measurement. |
