Abstract/OtherAbstract:
A bioimpedance system for the continuous measurement of non-invasive physiological parameters in lower-limb amputees is presented. The aim of the system is to monitor as many physiological parameters as possible from a single bioimpedance electrode configuration. In this way, a simple, low-cost and low-size autonomous system is developed that is able to continuously monitor the amputee in different environments (home, work, etc). The system measures both electrical impedance myography and electrical impedance plethysmography in the stump with electrodes placed in the inside face of a silicone interface. Such a system allows for the monitoring of a patient's muscle activity, and heart and breath rate, thus enabling the study and continuous monitoring of prosthesis adaptation and improvement of patient's gait to reduce physiological stress. Additionally, it can prevent cardiovascular problems due to the effort involved in the use of prostheses, which can decrease the life expectancy of amputees with previous vascular diseases. Experimental results obtained from different amputees' test validate the purpose of the system.
