PURPOSE: The aim of this study was to determine changes in physical activity, nutrition, sleep behaviour and body composition in wheelchair users with a chronic disability after 12 weeks of using the WHEELS mHealth application (app). METHODS: A 12-week pre-post intervention study was performed, starting …

BACKGROUND: Physical activity (PA) levels might be a simple overall physical function indicator of recovery in acutely hospitalized older adults; however it is unknown which amount and level of PA is associated with recovery. Our objective was to evaluate the amount and level of post discharge PA and …

The objective of this study is to investigate the heart rate (HR) accuracy measured at the wrist with the photoplethysmography (PPG) technique with a Fitbit Charge 2 (Fitbit Inc) in wheelchair users with spinal cord injury, how the activity intensity affects the HR accuracy, and whether this HR accuracy …

This week, JMIR (Journal of Medical Internet Research) Cardio published our paper ‘Moderation of the Stressor-Strain Process in Interns by Heart Rate Variability Measured With a Wearable and Smartphone App: Within-Subject Design Using Continuous Monitoring‘. In this blogpost, I’ll attempt to break down …

Background: The emergence of smartphones and wearable sensor technologies enables easy and unobtrusive monitoring of physiological and psychological data related to an individual’s resilience. Heart rate variability (HRV) is a promising biomarker for resilience based on between-subject population studies, …

OBJECTIVES: To determine the number of steps taken by older patients in hospital and 1 week after discharge; to identify factors associated with step numbers after discharge; and to examine the association between functional decline and step numbers after discharge. DESIGN: Prospective observational …

Data collected from fitness trackers worn by employees could be very useful for businesses. The sharing of this data with employers is already a well-established practice in the United States, and companies in Europe are showing an interest in the introduction of such devices among their workforces. …

Dit onderzoek is gedaan in opdracht van het Lectoraat van Mens & Technologie als onderdeel van het Quantified student project. Het doel van dit project is om het studiesucces en het studieplezier te kunnen verbeteren bij studenten. Binnen dit onderzoek is welbevinden het uitgangspunt geweest. Welbevinden …

Purpose: The purpose of this study was to validate optimized algorithm parameter settings for step count and physical behavior for a pocket worn activity tracker in older adults during ADL. Secondly, for a more relevant interpretation of the results, the performance of the optimized algorithm was compared …

Corona en de intelligente lock down heeft grote invloed op het beweeggedrag van mensen en de daarmee samenhangende consequenties voor de fysieke en mentale gezondheid, het immuunsysteem etc. Fitbit beschrijft in een blog op haar website de wereldwijde afname van lichamelijke activiteit afgemeten aan …
