Development of a Quantitative In-Shoe Measurement System for Assessing Balance: Sixteen-Sensor Insoles

This work presents the first phase in the development of an in-shoe sensor system designed to evaluate balance. Sixteen force-sensitive resistors were strategically mounted to a removable insole, and the bilateral outputs were recorded. The initial results indicate that these sensors are capable of detecting subtle changes in weight distribution, corresponding to the subject´s ability to balance. Preliminary analysis of this data found a clear correlation between the ability to balance and the state of health of the subject
