Validity of six consumer-level activity monitors for measuring steps in patients with chronic heart failure

  • Published on Sep 13, 2019

Introduction: Although numerous activity trackers have been validated in healthy populations, validation is lacking in chronic heart failure patients who normally walk at a slower pace, making it difficult for researchers and clinicians to implement activity monitors during physical activity interventions. Methods: Six consumer-level activity monitors were validated in a 3...



A randomised controlled trial to investigate the use of high-frequency airway oscillations as training to improve dyspnoea in COPD

  • Published on July 29, 2019

Introduction Chronic obstructive pulmonary disease (COPD) is characterised by expiratory flow limitation resulting in symptomatic dyspnoea, sputum retention and ventilation heterogeneity. Changes in breathing mechanics affect the ability of respiratory muscles to respond to the ventilatory demands, increasing the sensation of dyspnoea. A high-frequency airway oscillating device has been developed ...



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 ...
