Quantification of irregular circadian cycles using time-series methods

  • Published on April 10, 2019

Abstract The original focus of the field of chronobiology was to demonstrate that most – if not all – biological parameters are modulated in a regular way by the periodic alternation of day and night, called circadian cycles. Recently, it has become clear that adverse conditions such as ageing and/or disease ...


Actigraph assessment for measuring upper limb activity in unilateral cerebral palsy

  • Published on February 22, 2019

Background Detecting differences in upper limb use in children with unilateral cerebral palsy (UCP) is challenging and highly dependent on examiner experience. The recent introduction of technologies in the clinical environment, and in particular the use of wearable sensors, can provide quantitative measurement to overcome this issue. This study aims ...


Accuracy of the energy expenditure during uphill exercise measured by the Waist-worn ActiGraph

  • Published on January 23, 2019

Background The application of Micro-Electro-Mechanical Sensors (MEMS) as measurements of energy expenditure (EE) has certain disadvantages. For example, the inertial sensors cannot easily distinguish changes in ground slope during walking/running conditions, so the accuracy of EE calculation is biased. To resolve this issue, heart rate (HR) and heart rate ...


Telecommunication devices use, screen time and sleep in adolescents

  • Published on April, 2019

Purpose To investigate the association between telecommunication and other screen devices use and subjective and objective sleep measures in adolescents at 17–18 years. Methods Cross-sectional study on adolescents aged 17–18 years from a Spanish population-based birth cohort established in Menorca in 1997–1998. Information on devices use was collected using self-reported questionnaires. Mobile Phone ...


Protocol for a clinical trial of text messaging in addition to standard care versus standard care alone in prevention of type 2 diabetes through lifestyle modification in India and the UK

  • Published on Sept. 10, 2018

Background: Type 2 diabetes is a serious clinical problem in both India and the UK. Adoption of a healthy lifestyle through dietary and physical activity modification can help prevent type 2 diabetes. However, implementing lifestyle modification programmes to high risk groups is expensive and alternative cheaper methods are needed. We are using ...


Validity of three accelerometers to investigate lying, sitting, standing and walking

  • Published on May 23, 2019

Background: Hospital stays are associated with high levels of sedentary behavior and physical inactivity. To objectively investigate physical behavior of hospitalized patients, these is a need for valid measurement instruments. The aim of this study was to assess the criterion validity of three accelerometers to measure lying, sitting, standing and ...


Emerging Technologies for Assessing Physical Activity Behaviors in Space and Time

  • Published on January 28, 2014

Abstract: Precise measurement of physical activity is important for health research, providing a better understanding of activity location, type, duration, and intensity. This article describes a novel suite of tools to measure and analyze physical activity behaviors in spatial epidemiology research. We use individual-level, high-resolution, objective data collected in a ...


Real-world Use of Rescue Inhaler Sensors, Electronic Symptom Questionnaires and Physical Activity Monitors in COPD

  • Published on February 18, 2019

Background: Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease characterised by airflow obstruction and other morbidities such as respiratory symptoms, reduced physical activity and frequent bronchodilator use. Recent advances in personal digital monitoring devices can permit continuous collection of these data in COPD patients, but the relationships among them ...


Physical activity and sedentary behavior across three time-points and associations with social skills in early childhood

  • Published on Jan 7, 2019

Background: The growth and development that occurs in early childhood has long-term implications, therefore understanding the relevant determinants is needed to inform early prevention and intervention. The objectives of the study were to examine: 1) the longitudinal associations of physical activity and sedentary behavior with social skills and 2) how physical activity ...


Observational Study of a Wearable Sensor and Smartphone Application Supporting Unsupervised Exercises to Assess Pain and Stiffness

  • Published on Sept. 2018

Background: Evaluation of pain and stiffness in patients with arthritis is largely based on participants retrospectively reporting their self-perceived pain/stiffness. This is subjective and may not accurately reflect the true impact of therapeutic interventions. We now have access to sensor-based systems to continuously capture objective information regarding movement and ...
