- W2977505469 abstract "A plantar foot pressure measurement provides important information which can beused as a helpful tool for evaluating patients with foot complaints. Foot plantarpressure systems are devices that are used to measure underfoot pressure. They can beclassified into two types: platform systems and insole systems. An insole system isflexible and portable, thereby allowing a wider variety of studies to be carried out withdifferent gait tasks, footwear designs and terrains, while a platform system is fixed andlimited to the measurement of underfoot pressure in a static condition, and is usuallyused for the detection of ulceration. Currently, underfoot pressure ranges have not beeneffectively established, and there is insufficient information about the minimum andmaximum values of underfoot pressure. Likewise, constraints with regard to theimplementation of insole systems still persist and are represented by the need to put aspacer on the sensor during measurements, with the problem of sensor parameterschanging after the calibration. Therefore, optimization of measurement techniqueshave been proposed for the implementation of an insole system to measure theunderfoot pressure to overcome these drawbacks.This research was approved by the Human Research Ethics Committee of UniversitiPutra Malaysia. The research was aimed at measuring the pressure of 15 points underthe foot for 12 samples, divided into two groups (male and female). Two techniqueswere used to implement the insole system for the effective measurement of underfootpressure, namely a sensor optimization of the output voltage swing, and the setting ofthe physical characteristics of a spacer to be placed on the sensors. In addition, a self-calibration technique was employed with the insole system to maintain the sensormeasurements and to solve the problem of the changing of the sensor parameters aftera period of time following the calibration. The performance of the proposed deviceafter the application of these techniques was tested with an insole system based on thecalculation of the body weight. The results showed that the proposed insole plantarpressure device was able to measure the plantar pressure ranges effectively and was able to calculate the body weight with a measurement error of up to 5.07 % of the realvalue of the body weight using a weight scale. This was compared to the use of acommercial device (novel EMED system) which calculated the body weight with ameasurement error of up to 9.2 %, or the use of the current insole system without anyoptimization technique, which calculated the body weight with a measurement errorof up to 9.06 % from the real value. This work will contribute towards the benefit ofthe social and industrial sectors in terms of measurement precision." @default.
