Development of a smart insole device for lower limb postoperative rehabilitation training

摘要

A smart insole device is developed to fulfill the needs of evaluating rehabilitation effect for lower limb postoperative rehabilitation. The data acquisition module of the device was built by low power, high performance microprocessor and strain-type pressure sensors. Besides, the Bluetooth technology was applied to achieve wireless data transmission. In addition, the calibration of the accuracy of pressure acquisition was carried out, and the pressure data of normal persons and postoperative patients were collected. The preliminary analysis showed that the device could reflect the gait and the distribution of plantar pressure in the rehabilitation process, which could be used as a tool to evaluate the postoperative rehabilitation effect.
