We would like to provide comment on research recently published in the Journal of Vascular Surgery entitled "gait variability is altered in patients with peripheral arterial disease" by Myers et al. The Myers et al (2009) study complements previous work from our group. These studies suggest that patients who have peripheral arterial disease (PAD) display reduced temporal-spatial gait parameters and increased linear movement variability in the lower limbs compared with health, age, and mass matched controls. These gait abnormalities do not improve following a 12-month supervised exercise program despite increases in pain free walking distance.
