To determine the effects of using a rollator in people with chronic obstructive pulmonary disease (COPD).
Studies were systematically identified from literature searches of MEDLINE, CINAHL, PEDro, PubMed, EMBASE, and the Cochrane Library databases and the reference lists of included studies. Two reviewers independently selected randomized controlled or crossover studies examining the effects of rollator usage compared with no aid in individuals with COPD. Methodologic quality was assessed by 2 reviewers independently using the Cochrane Risk of Bias tool. Two reviewers also used a customized form to extract characteristics of and outcomes for subjects related to exercise capacity, symptoms, health-related quality of life (HRQOL), physiological, and gait parameters. Weighted mean differences (WMD) with 95% CI were calculated using a fixed-effects model.
A total of 7 studies (126 participants) were included. Use of a rollator during a 6-Minute Walk Test (6MWT) improved distance walked (WMD = 13 m; 95% CI, 5-22) and lowered end-6MWT dyspnea rating (WMD = 0.97; 95% CI, 0.63-1.32). Longer-term use did not appear to impact exercise capacity or HRQOL, although this may be related to the frequency of use.
When used in the short-term, rollators resulted in a small increase in 6MWT and a reduction in dyspnea. Details on patient adherence are required to accurately evaluate the longer-term effects of rollator usage.
确定在慢性阻塞性肺疾病（COPD）患者中使用助行器的效果。
从 MEDLINE、CINAHL、PEDro、PubMed、EMBASE 和 Cochrane 图书馆数据库以及纳入研究的参考文献中系统地搜索文献，确定研究。两名审查员独立选择了比较 COPD 患者使用助行器与不使用助行器对其影响的随机对照或交叉研究。两名审查员还使用定制表格提取与运动能力、症状、健康相关生活质量（HRQOL）、生理和步态参数相关的受试者的特征和结果。使用固定效应模型计算加权均数差值（WMD）和 95%置信区间（CI）。
共纳入 7 项研究（126 名参与者）。在 6 分钟步行测试（6MWT）中使用助行器可改善步行距离（WMD = 13 m；95%CI，5-22），并降低 6MWT 结束时的呼吸困难评分（WMD = 0.97；95%CI，0.63-1.32）。长期使用似乎不会影响运动能力或 HRQOL，尽管这可能与使用频率有关。
短期使用助行器可使 6MWT 略有增加，并减轻呼吸困难。需要详细了解患者的依从性，以准确评估助行器使用的长期效果。
