A device has been developed and used to monitor and record the repetitive stresses applied to a particular location under the foot of five diabetic and five control subjects. This device, targeted at individuals who suffer from diabetes, was designed to further understand and eventually prevent the formation of foot ulcers. Data collected from the 10 subjects was downloaded into a central database for correlation of the data with the formation of ulcers. Based on the results of the correlation, the device will be used to provide feedback to the:

  1. Patient - to augment their compromised protective sensation
  2. Health-care practitioner - for both percent efficacy of the orthosis and the risk level of the patient

The present prototype can record data for over two weeks without a battery change or data download. With a few small changes, this device will be able to record data for closer to a month. In this study, the patient population was too small and data was collected for too short a duration to determine any statistically significant correlation, but the study did provide positive results that this device can be effectively used to record and monitor the pressures under an individual's feet.
