We have designed, manufactured, and tested a prototype of an in-sole plantar pressure sensor. The sensor is made of a piezoelectric polymer film (polyvinylidenefluoride, PVDF) with evaporated copper electrodes. The size and the location of measuring sites are carefully considered to produce a light-weighted, practical, and inexpensive matrix sensor for measurement of plantar pressure distribution...
In today's life, biomedical field reach at higher level because of highest development in portable devices and the equipment which are being helping the patients in monitoring and controlling different disease at different stages. But in many work environments, the worker has lot pressure and continuous movement on daily basis which tends to foot related diseases as getting exact details about the...
In this paper, a low cost and flexible plantar pressure monitoring system is presented that is suited for everyday use to prevent pressure ulcers. To define the technical specifications of the sensor system, a gait analysis study was carried out. Analysis of measured data based on a multivariate approach and neural network classification shows that it is possible to dissociate between healthy and...
Foot problem diagnosis is often made by using pressure mapping systems, unfortunately located and used in the laboratories. In the context of e-health and telemedicine for home monitoring of patients having foot problems, our focus is to present an acceptable system for daily use. We developed an ambulatory instrumented insole using 3 pressures sensors to visualize plantar pressure cartographies....
Pathologies of the foot are amongst some of the most debilitating problems affecting individuals of all ages. Often, these pathologies are painful and correspond with high or abnormal plantar pressure, which can result in asymmetry between the feet during pathological gait. These problems, if left untreated, can escalate to severe plantar injury. The diagnosis of plantar pressure abnormalities can...
This study was designed to assess the effect of time on the repeatability of the LorAn pressure distribution measurement system, and evaluate the variability of plantar pressure and postural balance, during barefoot standing in diabetic and non-diabetic subjects, for future diabetic foot clinical evaluation. Fourteen subjects were evaluated (8 females, 6 males, 8 non-diabetics and 6 diabetics, age...
It has been well documented that subjects with peripheral neuropathy resulting from diabetes mellitus are at high risk of developing foot ulceration. Decreased sensation, in combination with high underfoot pressures, have been identified as prime etiology factors in the cause of plantar naturopathic ulceration. This study presents the effect of four orthotic treatment techniques in reducing metatarsal...
This paper aims at development of low cost dynamic foot pressure scanner. To estimate the peak pressure points on the foot sole, a study was conducted on a healthy male group. In all, 8 subjects were placed for observation on EMED (from Novel Inc.) foot mat system at different clinics. The data, thus recorded, was analyzed using Novel-Win-Mask software and it is concluded that, on a single pressure...
The authors have developed a portable, microprocessor-based data-acquisition system to measure pressures between the foot and shoe of ambulatory subjects. They attached seven pressure sensors to the surface of each insole of a pair of extra-deep shoes. They were located under the center of the heel, the five metatarsal heads, and the big toe of each foot. This system continuously collects raw pressure...
