Chronic neck pain (CNP) causes decreased functionality of the upper extremity. A standardized measurement tool is needed for evaluating upper limb capacity in patients with CNP. The unsupported upper-limb exercise test (UULEX) is a simple, inexpensive field test developed to measure peak arm exercise capacity, but there has been no report of its validity and reliability for use with patients with CNP. Our aim in this study was to determine the validity and test-retest reliability of the UULEX for this purpose. In this cross-sectional observational study, 44 patients (33 women, 11 men; age = 37.7, = 13.2 years), performed the UULEX twice, within a 1-week interval for test-retest reliability as measured by the intraclass correlation coefficient (ICC). We correlated the UULEX with the Six Minute Pegboard Ring Test (6PBRT), the 30-second Push-Up Test, and the Disability of Arm, Shoulder, and Hand Questionnaire (DASH) to assess its convergent validity. The UULEX demonstrated excellent test-retest reliability with ICC = 0.97 and 0.95 for test duration and the final weight on board, respectively. We found moderate to strong correlations between the UULEX and the 6PBRT ( = 0.844), the 30-second Push Up Test ( = 0.741) and the DASH ( = -0.639), and all were significant, ( < 0.05). MDC values were determined to be 57.7 seconds for test duration and 0.22 kg for final weight on board. Thus, the UULEX test was valid and reliable for assessing upper extremity functional capacity in patients with CNP.
慢性颈痛（CNP）导致上肢功能下降。需要一种标准化的测量工具来评估 CNP 患者的上肢能力。无支撑上肢运动测试（UULEX）是一种简单、廉价的现场测试，旨在测量峰值手臂运动能力，但尚未有关于其在 CNP 患者中有效性和可靠性的报告。我们旨在研究目的是确定 UULEX 的有效性和重测信度。在这项横断面观察性研究中，44 名患者（33 名女性，11 名男性；年龄=37.7，=13.2 岁），在 1 周的间隔内进行了两次 UULEX 测试，重测信度通过组内相关系数（ICC）进行测量。我们将 UULEX 与六分钟指板环测试（6PBRT）、30 秒俯卧撑测试和手臂、肩部和手残疾问卷（DASH）进行相关性分析，以评估其收敛效度。UULEX 具有极好的重测信度，ICC 分别为 0.97 和 0.95，用于测试持续时间和最终重量。我们发现 UULEX 与 6PBRT（=0.844）、30 秒俯卧撑测试（=0.741）和 DASH（=-0.639）之间存在中度至高度相关性，且均具有统计学意义（<0.05）。测试持续时间的 MDC 值为 57.7 秒，最终重量的 MDC 值为 0.22 公斤。因此，UULEX 测试可有效可靠地评估 CNP 患者的上肢功能能力。
