Smartwatches Can Detect Walker and Cane Use in Older Adults

  • Published on April 22, 2019

Background and Objectives Clinicians commonly prescribe assistive devices such as walkers or canes to reduce older adults’ fall risk. However, older adults may not consistently use their assistive device, and measuring adherence can be challenging due to self-report bias or cognitive deficits. Because walking patterns can change while using an ...


Detection of Pediatric Upper Extremity Motor Activity and Deficits With Accelerometry

  • Published on April 26, 2019

Importance Affordable, quantitative methods to screen children for developmental delays are needed. Motor milestones can be an indicator of developmental delay and may be used to track developmental progress. Accelerometry offers a way to gather real-world information about pediatric motor behavior. Objective To develop a referent cohort of pediatric accelerometry ...


The ActiGraph counts processing and the assessment of vigorous activity

  • Published on April 13, 2019

Summary The purpose of this study was to investigate the effect of different band‐pass filters on the measurement bias with ActiGraph counts during high speed running and for estimating free‐living vigorous physical activity (VPA). Two alternative band‐pass filters were designed, extending the original frequency range from 0·29 to 1·66 ...


Video Games That Encourage Healthy Behavior Did Not Alter Fasting Insulin or Other Diabetes Risks in Children: Randomized Clinical Trial

  • Published on August 2, 2019

Background Previous research indicates games for health have substantial promise in promoting change in children's diet and physical activity (PA) behavior for obesity and diabetes prevention, but the research has generally not been rigorous. The study reported here was an efficacy trial of two role-playing video games played in sequence, “...


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 ...
