The incremental and endurance shuttle walking tests (ISWT and ESWT) are measures of exercise tolerance commonly used in pulmonary rehabilitation (PR). A practice ISWT is advocated but often omitted by PR centres. We aimed to investigate the effect of such an omission within a clinical PR service. Between October 2002 and October 2008, 392 patients attending PR completed a practice ISWT and an ISWT. Results showed that patients walked significantly further on ISWT compared to practice ISWT (p ≤ 0.001). A significant difference in ESWT level was found between those calculated from practice ISWT and those calculated from ISWT (p ≤ .001). Despite a visual trend towards a negative relationship between distance walked at baseline (practice ISWT) and magnitude of the difference between the two walks, this did not meet statistical significance (p = 0.409). Absence of a practice ISWT could lead to possible clinical misjudgements.
递增耐力穿梭步行测试（ISWT 和 ESWT）是肺康复（PR）中常用的运动耐量测量方法。提倡进行练习 ISWT，但 PR 中心经常省略该步骤。我们旨在调查在临床 PR 服务中省略该步骤的影响。2002 年 10 月至 2008 年 10 月期间，392 名参加 PR 的患者完成了练习 ISWT 和 ISWT。结果表明，患者在 ISWT 上的行走距离明显长于练习 ISWT（p ≤ 0.001）。从练习 ISWT 和 ISWT 计算得出的 ESWT 水平存在显著差异（p ≤.001）。尽管在基线（练习 ISWT）行走距离和两次行走之间的差异幅度之间存在负相关的趋势，但这并未达到统计学意义（p = 0.409）。缺少练习 ISWT 可能会导致可能的临床误判。
