Validity of Activity Monitors to Study Walking

Completed

• Conditions: Validity Study of Activity Monitors in Healthy Subjects

• Registration Number: NCT05446454
• Lead Sponsor: University of Rennes 2

Brief Summary

Wearable activity monitors represent a real opportunity to assess people' daily walking activity, however their level of validity remains poorly understood in the assessment of intermittent walking activity, i.e. as it occurs in everyday life conditions. Indeed, the available validation studies mainly focused on steps count accuracy of wearable activity monitors, but their validity to detect and quantify bouts of intermittent walking in daily life conditions remains insufficiently studied. It is important not only to determine which indicators would be the most accurate but also which methods would be the most suitable for detecting intermittent walking bouts, and then estimating energy expenditure. The main objective of the VAMOS project is to study the criterion and convergent validity of consumer-level and research-grade wearable activity monitors in assessing daily life intermittent walking in healthy subjects.
