AB Accelerometers can estimate the intensity, frequency, and duration of physical activityin healthy adults. Although thresholds to distinguish varying levels of activity intensity using theActigraph wGT3X-B have been established for the general population, their accuracy for Huntington’sdisease (HD) is unknown. We aimed to define and cross-validate accelerometer cut-points for differentwalking 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 HDparticipants. The accelerometer was placed around the right hip, and a heart monitor was fittedaround the chest to monitor heart rate variability. Participants walked on a treadmill at three speedswith light, moderate and vigorous intensities. Correlation and receiver operation curve analyses wereperformed between the accelerometer magnitude vector with relative oxygen and heart rate. Optimalcut-points for walking speeds of 3.2 km/h were ≤2852; 5.2 km/h: >2852 to ≤4117, and in incrementsuntil their maximum velocity: >4117. Our results support the application of the disease-specificcut-points for quantifying physical activity in patients with mild to moderate HD and promotinghealthy lifestyle interventions.
