背景：初步证据表明COPD患者表现出平衡缺陷。需要对这些患者的平衡和福尔斯风险进行进一步研究。本研究的目的是确定的临床措施，区分从非步履蹒跚的COPD patients.Methods：采用横断面研究设计。> 60岁的COPD受试者参加了一次评估会议。通过自我报告问卷收集1年福尔斯发生率。使用贝格平衡量表（BBS）、定时起身和行走测试（TUG）和活动特定平衡信心（ABC）量表确定福尔斯和平衡的风险。运动耐量测定从六分钟步行试验和功能限制归因于呼吸困难从医学研究理事会（MRC）呼吸困难scale.Results：39 COPD受试者（FEV 1 = 41.5 +/- 17.0%预测值;年龄：71.1 +/- 6.8岁）谁完成了这项研究，46%（n = 18）报告至少有一个下降在前一年。跌倒者和非跌倒者之间的ABC存在显著差异（65.8 +/- 18.2 vs. 81.7 +/- 11。1个; p = 0.002），TUG（17.0 +/- 4.9 vs. 14.0 +/- 3.1 s; p = 0.024），BBS（45.2 ± 5.4 vs. 48.8 ± 5.0; p = 0.042），使用辅助供氧（72%对24%; p = 0.002）和MRC呼吸困难量表（中位数4，范围3对中位数3，范围4; p = 0.046）。标准的临床平衡测量可以区分自我报告的步履蹒跚和非步履蹒跚。这些观察结果引起了人们对COPD重要继发性损害的关注。皇冠版权所有（C）2009由爱思唯尔有限公司出版。保留所有权利。
Background: Preliminary evidence suggests individuals with COPD exhibit deficits in balance. Further investigation of balance and risk of falls is warranted in these patients. The objective of this study was to determine the clinical measures that discriminate falters from non-falters among patients with COPD.Methods: A cross-sectional study design was used. Subjects > 60 years with COPD attended a single assessment session. A one-year incidence of falls was collected via self-report questionnaire. Risk of falls and balance were determined using the Berg Balance Scale (BBS), Timed Up and Go Test (TUG) and the Activity-Specific Balance Confidence (ABC) Scale. Exercise tolerance was determined from the Six-Minute Walk Test and functional Limitation attributable to dyspnea from the Medical Research Council (MRC] dyspnea scale.Results: Of the 39 COPD subjects (FEV1 = 41.5 +/- 17.0% predicted; age: 71.1 +/- 6.8 years) who completed the study, 46% (n = 18) reported at least one fall in the preceding year. Significant differences between falters and non-fallers were found for the ABC (65.8 +/- 18.2 vs. 81.7 +/- 11. 1; p = 0.002), TUG (17.0 +/- 4.9 vs. 14.0 +/- 3.1 s; p = 0.024), BBS (45.2 +/- 5.4 vs. 48.8 +/- 5.0; p = 0.042), use of supplemental oxygen (72% vs. 24%; p = 0.002), and MRC dyspnea scale (median 4, range 3 vs. median 3, range 4; p = 0.046).Conclusions: Patients with COPD fait frequently. Standard clinical balance measures discriminate self-reported falters from non-falters. These observations draw attention to an important secondary impairment in COPD.
