Abstract
BackgroundThe aim of the present paper is to assess the gait pattern of patients with Peripheral Artery Disease (PAD). A more specific aim is to compare the gait pattern of PAD patients before and after the appearance of intermittent claudication symptoms.MethodsThe study involved 34 PAD patients with a claudication distance ≥200 m and 20 participants without PAD, who formed the control group. The gait pattern of PAD patients was assessed twice: before the appearance of intermittent claudication symptoms (pain-free conditions) and after the appearance of intermittent claudication symptoms (pain conditions).ResultsCompared to the control group, PAD patients presented a statistically significant decrease in step length both during pain-free conditions (52.6 ± 12.5 vs. 72.8 ± 18.5 cm, p = 0.008) and in pain conditions (53.3 ± 13.3 vs. 72.8 ± 18.5 cm, p = 0.006). As for the remaining spatiotemporal parameters, there were no differences observed between the patient group and the controls. Intermittent claudication symptom induced by the walking test on the treadmill did not bring about any new abnormalities in the gait pattern or intensify the existing abnormalities of the gait.ConclusionsPAD patients have a tendency to shorten their step length regardless of the presence of intermittent claudication.
Highlights
The aim of the present paper is to assess the gait pattern of patients with Peripheral Artery Disease (PAD)
It is believed that PAD patients move more slowly and tend to take shorter steps compared to the healthy population [4, 5]
The main aim of the present work was to assess the gait pattern of PAD patients
Summary
The aim of the present paper is to assess the gait pattern of patients with Peripheral Artery Disease (PAD). A more specific aim is to compare the gait pattern of PAD patients before and after the appearance of intermittent claudication symptoms. The most frequent symptom of PAD (Peripheral Artery Disease) is intermittent claudication. It manifests itself through pain occurring in one or both lower limbs during physical exercise, and its growing intensity forces the patient to rest. The pain in lower limb muscles is connected with temporary ischaemia caused by arterial occlusion or stenosis. It is believed that in the course of PAD, the proportional share of particular phases of the gait cycle is altered. In the case of symptoms diagnosed only in one lower limb, the
