Abstract

The life of many limbs disabled patients as a result of illness and accident can be improved using physiotherapy. These patients need to undergo rehabilitation and supervise by physiotherapists.One of the activities of rehabilitation is self-propelling in a wheelchair by the patients.This is to monitor their physical and mental stability.As the number of these patients are gradually increasing and outnumbering physiotherapist from day to day, therefore an electronic monitoring system is needed. However,to determine the self-propelling action by the patients themselves on wheelchair is a challenge due to many factors which include many possibilities of movements.In this project,a monitoring system is being proposed using an accelerometer and integrated with an optical sensor to detect movement while measure the distance travelling by the patient on their own in order to accurately report to physiotherapist for following up with the progress of the rehabilitation of the patient and make a more accurate assessment on them.From the experiment,when accelerometer is attached on the upper chest of the subject,it shows a self-propelling action produce signals with maximum magnitude at the range of 0-5Hz compared to non self-propelling which have a lower maximum magnitude at the range of 5-20Hz.Then,when the accelerometer is attached to the lower chest of the subject,it shows a self-propelling action produce signals with maximum magnitude at the range of 0-5Hz,similar to the result when accelerometer is attached to the upper chest of subject.Meanwhile,the non self-propelling action when accelerometer is attached to the lower chest of subject produces a minimum magnitude of 5-15Hz.
