Validating a new algorithm to measure daily energy expenditure in people with movement limitations

Official title: Validating a New Machine-Learned Accelerometer Algorithm Using Doubly Labeled Water

Run by University of Wisconsin, Milwaukee · NCT05736302 · Data updated 2026-11-12

This study is testing a new device that measures how much energy people with movement limitations use in a day to see if it's more accurate than the current methods.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who can ambulate independently and have access to a smartphone and computer.

Probably not a fit

Patients who are wheelchair reliant, use assistive walking devices, or have uncontrolled hypertension or cognitive impairments may not benefit from this study.

What this trial studies

This observational study aims to validate a machine-learned accelerometer algorithm designed to estimate total daily energy expenditure (TDEE) in adults with movement disorders. The current algorithms are inadequate for individuals with functional limitations, so this study will compare the new algorithm's accuracy against the doubly labeled water technique, a gold standard for measuring TDEE. Approximately 125 adults will participate, undergoing physical assessments, metabolic rate examinations, and wearing accelerometers for data collection over 8-10 days.

Why it matters

Potential benefit: If successful, this study could provide a more accurate method for assessing energy expenditure in individuals with movement limitations, leading to better-targeted physical activity interventions.

How similar studies have gone: Other studies have shown success in validating algorithms for energy expenditure measurement, but this specific approach for individuals with movement limitations is relatively novel.
