Unsupported arm exercise tests have been used to evaluate the effects of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD), but the reliability and validity of these tests are not established.
We evaluated the test-retest reliability and validity of a 6-minute pegboard and ring test (PBRT) in 27 outpatients with COPD and 30 age-matched controls.
We evaluated a 6-minute PBRT, subject demographics, pulmonary function and disease-specific quality of life questionnaire, and the Pulmonary Functional Status Dyspnea Questionnaire-Modified version in 27 patients with COPD.
Highly significant correlation coefficients (r = .91, P < .001) were found between test and retest of PBRT scores. Statistically significant correlation coefficients were found between PBRT scores and pulmonary function tests such as FEV1% pred and FVC% pred, and activity domain and subdomain of Pulmonary Functional Status Dyspnea Questionnaire-Modified (P <or= .045). In addition, PBRT scores of healthy subjects were significantly higher than those of COPD subjects (P < .001), and were inversely related to age (P = .031). The FEV1% predicted and gender together accounted for 50% of the variance in the PBRT scores of patients with COPD.
PBRT is a reliable and valid method to assess unsupported arm exercise endurance in patients with COPD.
无支撑手臂运动试验已被用于评估慢性阻塞性肺疾病（COPD）患者肺康复的效果，但这些试验的可靠性和有效性尚未确立。
我们评估了27例COPD门诊患者和30例年龄匹配的对照组患者进行6分钟钉板和套环试验（PBRT）的重测信度和效度。
我们对27例COPD患者进行了6分钟PBRT、受试者人口统计学资料、肺功能和疾病特异性生活质量问卷以及改良版肺功能状态呼吸困难问卷的评估。
PBRT评分的测试和重测之间发现高度显著的相关系数（r = 0.91，P < 0.001）。在PBRT评分与肺功能测试（如FEV1%预计值和FVC%预计值）以及改良版肺功能状态呼吸困难问卷的活动领域和子领域之间发现了具有统计学意义的相关系数（P≤0.045）。此外，健康受试者的PBRT评分显著高于COPD受试者（P < 0.001），且与年龄呈负相关（P = 0.031）。FEV1%预计值和性别共同解释了COPD患者PBRT评分中50%的变异。
PBRT是评估COPD患者无支撑手臂运动耐力的一种可靠且有效的方法。
