Cross-sectional survey on researchers' experience in using accelerometers in health-related studies.

Objectives: Accelerometers are widely applied in health studies, but lack of standardisation regarding device placement, sampling and data processing hampers comparability between studies. The objectives of this study were to assess how accelerometers are applied in health-related research and problems with accelerometer hardware and software encountered by researchers.

Methods: Researchers applying accelerometry in a health context were invited to a cross-sectional web-based survey (August 2020-September 2020).
