Abstract:

A sensor interface device (e.g., orthotic device or immobilization device) is disclosed. More specifically, described is an individualized sensor device and system to prevent tissue damage resulting from, for example, pressure, torsion, temperature, shear, altered blood flow, reduced oxygen tension, pH levels, tissue conductivity, tissue viscoelasticity, infection and sweat chloride levels. In particular embodiments, the systems, devices and related methods are used for preventing ambulation and mobility related plantar tissue related damage and immobilizing tissues.

Abstract:

A system and a method predict risk of diabetic foot ulcer by automatically recognizing and tracking physiological activities of a person using a smart textile that has a plurality of pressure sensors and a plurality of temperature sensors. Pressure data indicative of plantar pressure applied to each of the pressure sensors by the person is received from the smart textile. Temperature data indicative of plantar temperature at each of the temperature sensors is received from the smart textile. Plantar parameters are determined from the pressure and temperature data and plantar responses to activity of the person are determined from the plantar parameters. A risk of the person developing a foot ulcer is determined based upon the plantar parameters and the plantar responses.

Abstract:

Methods, devices, and systems according to present principles provide ways to diagnose frailty and assess the severity of its clinical status—e.g., non-frail, pre-frail, and frail, especially as measured and quantified during activities of daily living. Systems and methods according to present principles objectively quantify physical activity behaviors and identify specific motor tasks, which indicate clinical frailty syndrome behaviors such as flopping, cautious-sitting, non-uniform walking fluctuations, cognitive decline, slowness, weakness, and exhaustion. Additionally, the systems and methods allow improved sensitivity and specificity of frailty identification by further assessing physiological parameters such as heart rate, respiration rate, and skin temperature in response to, or recovery from, specific activities.
