Physical behaviour can be described as actions performed by an individual throughout the day, for example, sleep, exercise, physical activity, and sedentary behaviour, and also include negative events such as falls. Body-worn sensors and connected objects now enable tracking of physical behaviour over extended periods of time and the technology and the application of it still proceed to develop. Monitoring of physical behaviour during daily life helps broadening our understanding of age-related and/or neurological decline; it can be used to monitor longitudinal changes, inform tailored interventions, and assess effect of interventions as well as facilitating development of patient-centred outcome.

We invite papers that stimulate the continuing efforts to better understand physical behaviour as part of preventive health care and rehabilitation. We are looking for studies of a reasonable size that provide in depth understanding of methodological issues of measurement, analysis, visualisation, inference, and deployment and how the technology can be used to improve decision making and self-management in patients. Articles could be original papers based on observational or experimental study designs or be review studies. Validation studies do not fall within the scope of the call. The papers need to be based on objective long term monitoring of physical behaviour.

Potential topics include, but are not limited to:

• Innovative use of existing technology
• The advantages of combing multiple technologies and sensors
• Data analysis and management and data protection issues
• Development and description of new activity features
• Application and integration of objective monitoring in health care
• Studies demonstrating how the technologies can be used to improve rehabilitation
