Integrated sensor system for gait analysis
The paper is about the work done for the requirement of gait analysis on the shoe for a limped person. The method adopted can help the doctor to treat a person with gait abnormalities. Gait analysis deals with the study of walking pattern, in order to understand the gait abnormalities. To treat these gait abnormalities it's necessary to analyse gait parameters such as foot angle, stride distance, step distance, step count, cadence, speed, progression line etc. This project presents a shoe device to measure these parameters with the help of various sensors such as accelerometer, ultrasonic sensor, gyroscope, foot pressure sensor, flex sensor etc. These sensors can be placed in the shoe such that sensors can accurately measure these parameters. The digital output of these sensors can be integrated through a controller and the result of the patient is sent to the doctor's phone or to a GSM device. Hence, this wireless shoe device helps to overcome the disadvantages of the existing system which is practiced in gait motion analysis laboratory. Results of shoe device can be compared with the gait of a normal person in order to differentiate and study the abnormal and normal gait of a person. The development of shoe device is mainly concerned with features like low cost, portable, ease of use and accurate measurements of gait parameters. The objective of shoe integrated sensor system for gait analysis is to provide better digital output results of the abnormal parameters and efficient way of analyzing than clinical gait. This device has various applications in sports for exercise training, medicinally in treating paralyzed patients and in biometric and forensics to identify/improve individual patient by making minor variations.
