Although thresholds to distinguish varying levels of activity intensity using the Actigraph wGT3X-B have been established for the general population, their accuracy for Huntington’s disease (HD) is unknown. We aimed to define and cross-validate accelerometer cut-points for different walking speeds in adults with mild to moderate HD. A cross-sectional, multicentre, case-control, observational study was conducted with a convenience sample of 13 symptomatic ambulatory HD participants. The accelerometer was placed around the right hip, and a heart monitor was fitted around the chest to monitor heart rate variability. Participants walked on a treadmill at three speeds with light, moderate and vigorous intensities. Correlation and receiver operation curve analyses were performed between the accelerometer magnitude vector with relative oxygen and heart rate. Optimal cut-points for walking speeds of 3.2 km/h were ≤2852; 5.2 km/h: >2852 to ≤4117, and in increments until their maximum velocity: >4117. Our results support the application of the disease-specific cut-points for quantifying physical activity in patients with mild to moderate HD and promoting healthy lifestyle interventions. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2022 The Authors Atribución 4.0 Internacional Energy metabolism Metabolismo energético Rehabilitation Rehabilitación Neurosciences Huntington's disease Corea (Enfermedad) Calorimetry Calorimetría Exercise - Health aspects Ejercicio - Aspectos de salud Running Marcha (Deportes) Accelerometer cut-points for physical activity assessment in adults with mild to moderate huntington’s disease: A cross-sectional multicentre study info:eu-repo/semantics/article
