AN IN-SHOE COMPLIANCE MONITOR FOR THERAPEUTIC FOOTWEAR 1. INTRODUCTION When a patient is prescribed therapeutic footwear, the clinician wants to know if the patient actually is wearing the footwear and using it as requested. If not, the cost of the footwear and the clinician’s time are wasted. We are developing a miniature, in-shoe compliance monitor for therapeutic shoes. Here, we describe our work on feasibility testing of in-shoe electronic hardware and software for the compliance monitor. 2. A DESIRED IN-SHOE COMPLIANCE MONITOR Our goal is an in-shoe compliance monitor that requires nothing on the part of the patient and that has no effect on the patient’s perception and experience when wearing the shoe. We want the monitor to be small, robust, low-cost, and single- use and to operate without any attention for up to 8 weeks. We also want it to be easy for the clinician to initialize and place the monitor in the shoe and to retrieve its log of patient compliance data after a monitoring period. 3. THE CLINICIAN’S USE OF THE COMPLIANCE MONITOR We envision an in-shoe compliance monitor used by the clinician as follows: To monitor a patient, the clinician activates the monitor and connects it via a cable to a personal computer (PC) USB port to download into it patient identification information and start time. The clinician then disconnects the monitor and inserts the monitor in the patient’s shoe. Insertion includes positioning a thin pressure sensor as appropriate for the patient. After the monitoring period, the OUR GOAL IS AN IN-SHOE COMPLIANCE MONITOR THAT REQUIRES NOTHING ON THE PART OF THE NO EFFECT ON THE PATIENT’S PERCEPTION AND EXPERIENCE WHEN WEARING THE SHOE. 42 Pedorthic Footcare Association PATIENT AND THAT HAS
