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 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).
Compared 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.
PAD patients have a tendency to shorten their step length regardless of the presence of intermittent claudication.
本研究旨在评估外周动脉疾病（PAD）患者的步态模式。更具体的目标是比较 PAD 患者在间歇性跛行症状出现前后的步态模式。
该研究纳入了 34 名跛行距离≥200 米的 PAD 患者和 20 名无 PAD 的参与者作为对照组。两次评估 PAD 患者的步态模式：在间歇性跛行症状出现前（无痛状态）和出现间歇性跛行症状后（疼痛状态）。
与对照组相比，PAD 患者在无痛状态下（52.6±12.5 厘米对 72.8±18.5 厘米，p=0.008）和疼痛状态下（53.3±13.3 厘米对 72.8±18.5 厘米，p=0.006）时步长明显缩短。对于其余时空参数，患者组与对照组之间没有差异。跑步机行走试验引起的间歇性跛行症状并没有导致步态模式出现新的异常，也没有加重现有的步态异常。
PAD 患者无论是否存在间歇性跛行，都有缩短步长的趋势。
