For patients with some chronic diseases, peripheral edema is a crucial indicator of onset or exacerbation of the condition. Thus, early detection of peripheral edema is important for timely diagnosis of associated diseases. However, existing techniques for edema assessment are a subjective measurement for which a human operator estimates the amount of swelling using a tape measure or by pressing the swollen area with the tip of an index finger. As a systematic approach to assessing peripheral edema, we develop SwellFit, an experimental prototype of a novel wearable technology that monitors peripheral edema by tracking changes in ankle curvature. Through a series of proof-of-concept experiments, we demonstrate that SwellFit detects ankle swelling even in the presence of substantial noise in the raw sensor readings.9 pagesengAttribution-NonCommercial-NoDerivatives 4.0 InternationalHealthcare Oriented Implementation of Wearable DevicesInformation Technology in HealthcareActivity Monitoring, Flex Sensor, Health IT, Swelling, WearablesConference Paper10.24251/HICSS.2019.468
