Chronic pain, sensory disturbances, and lymphedema are frequent after breast cancer, leading to arm dysfunction. There is a need for objective performance-based clinical exercise tests for the upper extremity in patients with breast cancer.
The aim of this study was to evaluate the validity and reliability of the 6-minute pegboard and ring test (6PBRT) in breast cancer survivors.
Forty-eight women with breast cancer (mean age = 55.40 ± 10.40 years) were included. All patients performed 6PBRT on the first day and one week later to investigate the test-retest reliability of the 6PBRT, and intraclass correlation coefficients (ICC) were calculated. The peak workload (W) and oxygen consumption level (VO) during the arm ergometer test were used as outcomes for the criterion validity of the 6PBRT.
The 6PBRT showed good test - retest reliability with an ICC value of 0.871 [95% confidence interval (CI) 0.769-0.928]. The first 6PBRT score was very strongly correlated with the second test score ( = 0.866, < .001). The 6PBRT score was significantly correlated with VO ( = 0.634, < .001), and W ( = 0.546, < .001). While the 6PBRT score had less effect on VO, the determination of VO in the model was very good (R = 0.832).
The 6PBRT has good test-retest reliability and is a valid test in individuals with breast cancer. These findings suggest that 6PBRT is a practical, useful, valid and reliable assessment tool for determining functional arm exercise capacity in patients with breast cancer.
乳腺癌后慢性疼痛、感觉障碍和淋巴水肿很常见，会导致手臂功能障碍。乳腺癌患者需要基于客观表现的上肢临床运动测试。
本研究旨在评估乳腺癌幸存者中6分钟钉板和指环测试（6PBRT）的有效性和可靠性。
纳入48名乳腺癌女性（平均年龄=55.40±10.40岁）。所有患者在第一天和一周后进行6PBRT，以研究6PBRT的重测可靠性，并计算组内相关系数（ICC）。手臂测力计测试期间的峰值工作量（W）和耗氧量水平（VO）用作6PBRT标准效度的结果。
6PBRT显示出良好的重测可靠性，ICC值为0.871[95%置信区间（CI）0.769-0.928]。第一次6PBRT评分与第二次测试评分高度相关（=0.866，<0.001）。6PBRT评分与VO（=0.634，<0.001）和W（=0.546，<0.001）显著相关。虽然6PBRT评分对VO的影响较小，但模型中VO的测定效果很好（R=0.832）。
6PBRT具有良好的重测可靠性，对乳腺癌患者是一项有效的测试。这些发现表明，6PBRT是一种实用、有用、有效且可靠的评估工具，可用于确定乳腺癌患者的手臂功能运动能力。
