Fuzzy monitoring of in-bed postural changes for the prevention of pressure ulcers using inertial sensors attached to clothing. Journal of biomedical informatics, 107, 103476.1532-0464https://doi.org/10.1016/j.jbi.2020.103476https://www.sciencedirect.com/science/article/pii/S1532046420301040https://hdl.handle.net/10953/4391Postural changes while maintaining a correct body position are the most efficient method of preventing pressure ulcers. However, executing a protocol of postural changes over a long period of time is an arduous task for caregivers. To address this problem, we propose a fuzzy monitoring system for postural changes which recognizes in-bed postures by means of micro inertial sensors attached to patients’ clothes. First, we integrate a data-driven model to classify in-bed postures from the micro inertial sensors which are located in the socks and tshirt of the patient. Second, a knowledge-based fuzzy model computes the priority of postural changes for body zones based on expert-defined protocols. Results show encouraging performance in the classification of in-bed postures and high adaptability of the knowledge-based fuzzy approach.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Inertial sensorsPressure ulcersPose recognitionFuzzy logicinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
