Physical activity levels are low in the days, weeks, and months following dysvascular major lower limb amputation.

A significant number of participants declined to wear the accelerometer, and those who did wear it for fewer than 4 days were still included, which may affect data reliability. The study did not perform statistical analysis on the accelerometer data due to the limited sample size at each time point. Self-reported physical activity may be subject to recall bias or inaccuracies in intensity perception, particularly given the altered biomechanics post-amputation. The accelerometer placement on the intact leg may have missed upper body activity or specific wheelchair propulsion nuances not captured by leg counts. The study population was restricted to dysvascular amputations, so findings may not apply to traumatic or cancer-related amputations.

The authors declared no conflicts of interest. The study was financially supported by Stichting Beatrixoord Noord-Nederland, which provided the Activ8 devices and scales. The funders had no role in study design, data collection, analysis, or manuscript preparation.

Do not interpret the increase in physical activity over time as evidence that standard care is sufficient to achieve healthy activity levels. Activity remained low throughout the nine months, and the study was observational, so it cannot determine if specific interventions would have improved these outcomes.
