Abstract :
We have developed software to control a Holter type microprocessor based, portable, in-shoe, plantar pressure data acquisition system. The system is used to monitor long term plantar pressures during the performance of daily living activities. The unit is able to record in continuous or intermittent modes. Real time data compression is utilized to optimize memory storage. Software routines have been developed to test the pseudo static RAM before recording, perform refresh and drive a liquid crystal display module. The unit was evaluated during several multi-step trials with adult male subjects. The unit is considered to be appropriate for clinical application and long term study of daily living activities
