Tehan PE, Stewart S, Chuter VH, et al. - Via a cross-sectional pilot study, researchers measured lower limb vascular features [indicative of peripheral arterial disease (PAD)], using non-invasive chairside testing methods, in individuals with RA compared with matched controls, and to ascertain the correlation between vascular features and gait velocity as a measure of functional capacity in individuals with RA. Seventy-two persons were involved. No important variations between the RA and control groups for lower limb vascular features were noted. Individuals with RA walked considerably slower in comparison with controls. In contrast with those with normal toe brachial index [TBI], individuals with RA who had abnormal TBI, or abnormal qualitative Doppler walked considerably slower. No important relationship between ABI and gait velocity was discovered. In summary, in individuals with RA vs matched controls, this study did not recognize various lower limb vascular features. Nevertheless, abnormal Doppler and TBI results are related to slower walking velocity in individuals with RA.
