Gait Analysis Using Wearable Sensors

Abstract

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 movement, body mechanics and the activity of the muscles Gait analysis is used to assess 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. In this study low cost human motion analysis is developed using wearable inertial/gyroscopic sensors such as the MPU6050. It differs from the conventionally used 3D motion capturing cameras using IR mapping and ball tracking. The sensors can be affixed to any part of the body and can be used simultaneously. Using Euler’s angles and their definitions for the movement and expression of a body’s orientation in a 3-axis format the system works flawlessly.
