Abstract

One-third of all elderly patients fall each year and impaired balance has been recognized as a specific risk factor. Intermittent claudication is common among the elderly population, affecting approximately 5% of the population over the age of 50. The aim of this proof-of-concept study was to assess the prevalence of impaired balance among elderly claudicants and to assess each patient’s insight into their own risk of falling. A total of 58 claudicants (45 men), median age of 70 (interquartile range = 65-73) years, underwent objective balance assessment by using computerized dynamic posturography. As compared with 195 (5%) historic controls, 24 (41%) of the claudicants demonstrated abnormal balance when the Sensory Organization Test (SOT) was used. Vestibular dysfunction occurred in 52% of the claudicants. Abnormalities including somatosensory (22%), visual function (17%), and preferential reliance on inaccurate visual cues (17%) occurred less often. Prolonged Motor Control Test latency times were uncommon (n = 13) and were in most cases evenly distributed between those with normal (n = 7) and abnormal (n = 6) composite SOT scores. There was a significant difference in history of falling between claudicants with abnormal and normal SOT scores (p = 0.003), with a higher number of patients with abnormal SOT having experienced falling in the past year. However, no correlation between fear of falling and composite SOT score was found (Spearman rank correlation, r = 0.124; p = 0.381). Impaired balance, particularly secondary to vestibular problems, is very common among claudicants and may predispose to a high incidence of falls. Claudicants with abnormal balance are more likely to have a history of falls but not a fear of falling, thus potentially rendering these patients to be at a greater risk.

计算机动态体位照相对间歇性跛行患者平衡性的客观评价
每年有三分之一的老年患者跌倒,平衡能力受损已被认为是一个特定的危险因素。间歇性跛行在老年人中很常见,约占50岁以上人口的5%。这项概念验证性研究的目的是评估老年人平衡能力受损的普遍程度,并评估每位患者对自身跌倒风险的认识。共有58名患者(45名男性),年龄中位数为70岁(四分位数间距为65-73岁),采用计算机动态体位仪进行客观平衡评估。与195人(5%)的历史对照组相比,24人(41%)在使用感觉组织测试(SOT)时表现出平衡异常。52%的患者出现前庭功能障碍。包括体感(22%)、视觉功能(17%)和对不准确视觉线索的优先依赖(17%)在内的异常发生的频率较低。运动控制测试延迟时间延长不常见(n = 13),在大多数情况下均匀分布在正常(n = 7)和异常(n = 6)的综合SOT评分者之间。SOT评分异常和正常的受试者在跌倒史上有显著差异(p = 0.003),在过去一年中有过跌倒经历的SOT异常患者较多。但跌倒恐惧与综合SOT得分无相关性(Spearman秩相关,r = 0.124;P = 0.381)。平衡性受损,尤其是继发于前庭系统的问题,在跛行者中非常常见,并可能导致跌倒的高发。平衡不正常的跛行者更有可能有跌倒史,但不害怕跌倒,因此可能使这些患者处于更大的风险中。
