Previous studies have shown major deficits in gait for individuals with
peripheral arterial disease before and after the onset of pain. However, these
studies did not have subjects ambulate at similar velocities
and potential exists
that the differences in joint powers may have been due to differences in walking
velocity. The purpose of this study was to examine the joint moments and powers
of peripheral arterial disease limbs for subjects walking at similar
self-selected walking velocities as healthy controls prior to onset of any
symptoms. Results revealed peripheral arterial disease patients have reduced peak
hip power absorption in midstance (p=0.017), reduced peak knee power absorption
in early and late stance (p=0.037 and p=0.020 respectively),
and reduced peak
ankle power generation in late stance (p=0.021). This study reveals that the gait
of patients with peripheral arterial disease walking prior to the onset of any
leg symptoms is characterized by failure of specific and identifiable muscle
groups needed to perform normal walking and that these gait deficits are
independent of reduced gait velocity.
