In this study, a sensor system was designed and manufactured to measure the interface
pressure between the limbs (upper, lower)and the orthosis or between the stump and
the socket prosthesis. It is also used to determine the value and location of corrective
forces when using orthosis to correct deformities in the limbs or spine. The sensor
system consists of a force sensor mat (43.69mm x 43.69 mm), Arduino, an LCD
monitor, and connecting cables. When comparing the device manufactured in this
study with other devices, this device is characterized as lightweight, easy to move,
low cost, and gives instant pressure on the LCD screen. In this study, the
interventional pressure measurement system was manufactured and programmed and
compared to the F-Socket measurement system. The practical part was tested on a
patient suffering from med-lateral instability in the ankle joint at the right leg. The
interventional pressure between the leg and orthosis was measured in two ways in the
regions (posterior, lateral, medial). The first method using the pressure measurement
system manufactured in this study and the second method by using the F-Socket
device. The test results showed that the values of pressure readings using the
manufactured system are close to the values of pressure readings obtained when using
the F-Socket device. This indicates that the accuracy of the readings of the
manufactured system and can be used for research purposes as well as in the process
of placing pads in the appropriate place within the orthosis to correct the deformity or
help to provide valuable information on the manufacturing, modification and fitting
of prosthetic sockets, despite its simple structure and low cost as compared with F-Socket devise
