Upper-extremity exercise is for pulmonary rehabilitation. The 6-minute pegboard and ring test (6PBRT) was developed to evaluate arm exercise capacity in patients with chronic obstructive pulmonary disease (COPD). The purpose of this study was to characterize the 6PBRT and evaluate its relationship with upper-extremity activities of daily living (ADLs) in COPD patients.
Twenty outpatients with mild to very severe COPD underwent the 6PBRT and spirometry, and their maximal inspiratory and expiratory pressures and grip strength were measured. For the 6PBRT, subjects were asked to move as many rings as possible in 6 minutes, and the score was the number of moved rings during the 6-minute period. Upper-extremity ADLs were evaluated with the upper extremity activities subdomain of the modified Pulmonary Functional Status and Dyspnea Questionnaire. Upper-extremity ADLs were also measured objectively by using a wrist accelerometer every day for 1 week.
There was a positive correlation between 6PBRT score and inspiratory capacity (r = 0.71, P < 0.001), inspiratory capacity/total lung capacity predicted (r = 0.68, P < 0.01), and forced vial capacity (r = 0.57, P < 0.01). There was also a positive correlation between 6PBRT score and accelerometer count (r = 0.54, P < 0.05) and a negative correlation between 6PBRT score and arm activity score (ρ = -0.49, P < 0.05).
The 6PBRT may be a predictive test to maintain and improve upper-extremity ADL during pulmonary rehabilitation in patients with COPD.
上肢运动是肺康复的一部分。6 分钟指套环测试（6PBRT）是为了评估慢性阻塞性肺疾病（COPD）患者的手臂运动能力而开发的。本研究的目的是描述 6PBRT，并评估其与 COPD 患者上肢日常生活活动（ADL）的关系。
20 名轻至重度 COPD 门诊患者接受了 6PBRT 和肺功能检查，并测量了他们的最大吸气和呼气压力以及握力。在 6PBRT 中，要求患者在 6 分钟内尽可能多地移动环，得分是 6 分钟内移动的环数。上肢 ADL 使用改良的肺功能状态和呼吸困难问卷的上肢活动子域进行评估。还使用腕部加速度计每天客观测量上肢 ADL 1 周。
6PBRT 评分与吸气量（r = 0.71，P < 0.001）、吸气量/预计总肺容量（r = 0.68，P < 0.01）和用力肺活量（r = 0.57，P < 0.01）呈正相关。6PBRT 评分与加速度计计数（r = 0.54，P < 0.05）呈正相关，与手臂活动评分（ρ=-0.49，P < 0.05）呈负相关。
6PBRT 可能是预测 COPD 患者肺康复期间维持和改善上肢 ADL 的预测测试。
