目的：胸外科医师协会建议使用5米步行测试（5 MWT）作为成人心脏手术数据库中的一项结局指标，以预测心脏手术候选人的虚弱程度。然而，在文献中没有关于该试验性能的已发表报告。因此，本研究的目的是为心脏手术候选人提供5 MWT的描述性分析。方法：回顾性分析113例术前接受5 MWT的心脏手术候选人。从测试中计算的步态速度作为物理治疗师进行的术前测试的一部分完成。进行三次试验，试验之间休息最多一分钟。使用t检验确定试验、性别、辅助设备的使用以及步态或姿势偏差的差异。结果：受试者的平均步态速度为1.05（SD 0.26）m/s。从试验1到试验3，步态速度在统计学上显著增加0.05（0.08）m/s（p < 0.0001）。男性和女性之间的步态速度没有显着差异。使用辅助设备的参与者的平均步态速度为0.70（0.27），明显低于那些没有辅助的人，平均步态速度为1.08（0.24）m/s（p < 0.0001）。有明显步态或姿势偏差的参与者行走速度（平均值0.84，SD 0.22）也明显慢于无偏差的参与者（平均值1.15，SD 0.21）（p < 0.0001）。结论：从试验1到试验3，受试者的速度略有增加，加强了5 MWT较短距离的引用益处，这可能会限制疲劳。尽管具有统计学显著性，但从试验1到试验3的速度增加可能不具有临床显著性。当受试者有可观察到的步态或姿势偏差或使用辅助装置时，观察到步态速度明显较慢。
Purpose: The 5‐Meter Walk Test (5MWT) has been recommended for use by the Society of Thoracic Surgeons as an outcome measure in the Adult Cardiac Surgery Database to predict frailty in individuals who are candidates for cardiac surgery. However, there are no published reports of performance on this test in the literature. Therefore, the purpose of this study was to provide descriptive analysis of the 5MWT for individuals who were candidates for cardiac surgery. Methods: Retrospective analysis of 113 preoperative cardiac surgery candidates who underwent a 5MWT. Gait speed calculated from the test was completed as part of preoperative testing administered by physical therapists. Three trials were performed with up to a one minute rest between trials. Differences by trial, gender, use of assistive device, and gait or postural deviations were determined using t‐tests. Results: Mean gait speed was 1.05 (SD 0.26) m/s for the subjects. There was a statistically significant increase in gait speed from trial 1 to trial 3 by 0.05 (0.08) m/s (p < 0.0001). There were no significant differences in gait speed between males and females. Participants using assistive devices displayed a significantly slower mean gait speed of 0.70 (0.27) than those who walked unaided, with a mean gait speed of 1.08 (0.24) m/s (p < 0.0001). Participants with noted gait or postural deviations also walked significantly slower (mean 0.84, SD 0.22) than those without deviations (mean 1.15, SD 0.21) (p < 0.0001). Conclusions: Subjects displayed a slight increase in speed from trial 1 to trial 3, reinforcing a cited benefit of the shorter distance of the 5MWT that may limit fatigue. Although statistically significant, the increase in speed from trial 1 to 3 may not be clinically significant in relation to the intent of the test. Significantly slower gait speeds were noted when a subject had an observable gait or postural deviation or used an assistive device.
