Insights from last week’s Wearable Landscape meeting: a big thanks to our core members and supporting students for weekly developing the initiative — and (of course) having some fun along the way :)

Let’s keep building our living network! 🌍💡

Methodological Choices on 24-h Movement Behavior Assessment by Accelerometry: A Scoping Review - Sports Medicine - Open Background There are no reviews describing current measurement protocols and accelerometer processing decisions that are being used in 24-h MovBeh studies, across the lifespan. We aim to synthesise information...

📊 New review on 24-h movement behavior assessment using #accelerometers!
102 studies across all ages show huge variation in protocols — from wear-time rules and epoch lengths to cut-points and devices.

🗝️ Harmonization is key to make results more comparable across studies and countries.

🚀 Kick-off: #DelphiStudy on Wearable #Validation

We are excited to announce the start of our Delphi study on the development of
✅ a standardized reporting checklist for wearable validation studies, and
✅ a quality assessment tool for systematic evaluation.

#Wearables #OpenScience #Collaboration

Our colleague Irina Timm (@irinatimm.bsky.social) presented the Wearable Landscape poster at Germany’s biggest sports science conference 🎉

A catalog of validity indices for step counting wearable technologies during treadmill walking: the CADENCE-adults study - International Journal of Behavioral Nutrition and Physical Activity Background Standardized validation indices (i.e., accuracy, bias, and precision) provide a comprehensive comparison of step counting wearable technologies. Purpose To expand a previously published…

#Wearables step-count validation ✅⌚

In a study of 21 wearables on the treadmill, authors found significant effects of walking speed, wear position, and age on accuravy. Many wearables track steps reasonably well, independent from being a commercial or research-grade device.

#Validation is key 🗝️

Welcome to our Management Group!

Performance Evaluation of Algorithms to Estimate Daily Sedentary Time Using Wrist-Worn Sensors in Free-Living Adults Matthews et al. (2025). Journal for the Measurement of Physical Behaviour

🎯 Testing the accuracy of 21 #algorithms for estimating sedentary time with wrist-worn #wearables revealed only 5 (24%) were within 10% of the gold standard. Two machine learning 🤖 and three posture-based cut-points performed best.
Great contribution to identify precise algorithms for wearable data!

#MemberMonday Wrap-Up

Over the last 10 weeks, we’ve introduced our amazing Advisory Board – experts in the fields of wearables ⌚️, physical activity 🏃🏽‍♂️‍➡️, health research 💟 and more. A huge thanks to all for supporting our initative and stay tuned for more updates.

Measures included average acceler...

🚨New study targeting different wear locations in children with activPAL (thigh) & ActiGraph (wrist) revealed...
- differences on average acceleration
- strong agreement on intensity metrics
Great insights into comparable physical activity analysis across devices and wear locations.

Why is #validation essential for wearable-use in research?

Not all #wearables are created equal. Their validity depends on context such as target behavior, sensor placement, and assessed population. Therefore, validation studies are crucial to improve feedback and ensure measurment accuracy! 🎯

A study in patients with central disorders of hypersomnolence compared actigraphy algorithms versus 24 h polysomnography. The authors found a partly underestimation of nighttime sleep and a clear overestimation of daytime sleep and 24-h sleep. Caution for diagnosis.

New research alert 🚨
A memory-foam in-ear wearable shows strong agreement with gold standard polysomnography recordings in the assessment of sleep quality and even outperforms actigraphy. This enables simplified, accurate and low-cost home-based sleep monitoring.
