下肢周围动脉疾病(PAD)是动脉粥样硬化的常见表现,由于行走时腓肠肌、股部或臀部缺血而导致运动诱发的肌肉疼痛和间歇性跛行,影响患者行走能力。以往对间歇性跛行患者进行行走功能障碍评估多采用活动平板运动试验,以测定最大无痛行走时间。但不足之处是无法确定此类患者的步幅、步频或步速等项数值是否也出现下降。作者认为,在此类患者中,运动诱发下肢缺血性疼痛时,作为一种代偿性或防护性机制,能导致步态参数的变化。为此本文比较了19例具有间歇性跛行病史的男性患者(PAD值)与11名同年龄段男性健康人(对照组)的步态特征。
Arterial disease of the lower extremities (PAD) is a common manifestation of atherosclerosis. Muscle pain and intermittent claudication due to ischemia of the gastrocnemius, femur or buttocks while walking affect the ability of the patient to walk. In the past for patients with intermittent claudication walking dysfunction assessment using more active treadmill exercise test to determine the maximum painless walking time. However, the downside is that it is not possible to determine whether the number of steps, steps or paces for such patients has also decreased. In the authors’ opinion, exercise-induced ischemic pain in the lower limbs, as a compensatory or protective mechanism, can lead to changes in gait parameters in such patients. To this end, we compared the gait characteristics of 19 male patients with intermittent claudication (PAD) with 11 healthy men (control group) at the same age.
