System for Monitoring Posture and Physical Activity Using Accelerometers.

摘要

Accelerometers can be used to monitor physical activity in the home over prolonged periods. We describe a novel system for objectively and continuously monitoring movement, suitable for patients with chronic diseases including congestive heart failure and chronic obstructive pulmonary disease. The key design criteria were ease of use by, and comfort for, the patient together with the provision of clinically relevant information. The patient's posture, energy expenditure and movement are clinically important parameters that can be measured by accelerometry. A data processing schema in which these parameters are extracted is described.
