More than half of patients with intermittent claudication (IC) do not meet the minimum recommendations for physical activity (PA) and public health. Compared to healthy adults, they have a significantly lower daily PA level. PA differences are due to a IC subgroup with severe functional impairments. Because a low PA level is considered a strong predictor of mortality and functional decline, all health care workers should actively stimulate physical activities in IC. Future studies should assess the effects of treatment strategies including supervised exercise therapy on daily PA levels.
