Tissue electrical properties monitoring for the prevention of pressure sore

摘要: Background: Pressure sores are a significant problem in the healthcare sector. Although they may cause considerable morbidity, preventable.Objectives: The objectives of this study to (1) investigate electrical properties tissue close and away from pressure sore site, (2) establish new approach for objective, reliable, low-cost noninvasive screening or detection its early stage.Study Design: Randomised controlled trial.Methods: Fifteen patients participated study. They all had stage I II sacral sores. Tiny surface electrodes four-electrode configuration were used measurements recorded over frequency range 30–10 MHz.Results: Intraclass correlation coefficient (ICC) showed that (ICC > 0.90 measurements) good reliability validity. real part impedance (R) imaginary (X) measured sore...
