Automation of pressure control between orthosis and foot
Abstract
Automation of pressure control between orthosis and foot
Incoming article date: 16.04.2022The Interventional Pressure (IP) between the orthosis and the foot in this study was measured using an engineered sensor device. When using orthotic devices to correct deviation of the foot or limb, it is often used to assess the importance and position of corrective forces. The components of the sensor device are: a 43.5 x 43.5 mm force sensor mat, an LCD display, connecting wires, and an Arduino. The system developed in this study is described as lightweight, easy to move, and inexpensive compared to other devices. This study made and programmed a sensor to measure pressure between the orthosis and the foot in three areas, and compared it to the F-Socket sensor. The experimental test was performed on a patient who suffered from instability of the right leg at the ankle joint. In the posterior, lateral and medial regions, the interventional pressure between the tibia and the orthosis was calculated in two ways. The 1st method uses the sensor manufactured in this study (SCR), while the 2nd method uses the F-Socket sensor. The test results showed that the pressure readings obtained from the fabricated device were close to the results obtained using the F-Socket device.
