INTRODUCTION/AIMS: Tests for assessing upper extremity (UE) functional capacity in patients with Duchenne muscular dystrophy (DMD) are limited. This study aimed to evaluate the validity and reliability of the 6-min pegboard and ring test (6PBRT) as a practical tool for this purpose.
Children with DMD (n = 22) were evaluated using the 6PBRT for UE functional capacity, the Quick Disabilities of the Arm, Shoulder, and Hand (Q-DASH) for functionality, the Pediatric Quality of Life Inventory (PedsQL) for quality of life, and a dynamometer for handgrip strength and UE muscle strength.
The 6PBRT showed excellent test-retest reliability, with an intraclass correlation coefficient (ICC) of 0.978 (95% confidence interval, 0.946-0.984). A very strong positive correlation was observed between the test and retest 6PBRT mean scores (r = 0.981). The mean 6PBRT score exhibited moderate-to-strong correlations with handgrip strength (r = 0.653, r = 0.646, right/left, respectively), muscle strength (shoulder flexors [r = 0.793, r = 0.797, right/left, respectively], shoulder abductors (r = 0.763, r = 0.743, right/left, respectively), elbow flexors [r = 0.743, r = 0.755, right/left, respectively]), mean Q-DASH score (r = -0.555), and mean PedsQL score (r = 0.611).
The 6PBRT appears to be a valid and reliable measure for assessing upper extremity functional capacity in patients with DMD. This test is suitable for patients who are able to lift both hands above their heads.

引言/目的：评估杜氏肌营养不良症（DMD）患者上肢（UE）功能能力的测试方法有限。本研究旨在评估6分钟钉板和指环测试（6PBRT）作为实现此目的实用工具的有效性和可靠性。
使用6PBRT评估DMD患儿（n = 22）的UE功能能力，使用上肢、肩部和手部快速残疾评定量表（Q-DASH）评估功能，使用儿童生活质量量表（PedsQL）评估生活质量，并使用握力计评估握力和UE肌肉力量。
6PBRT显示出出色的重测可靠性，组内相关系数（ICC）为0.978（95%置信区间，0.946 - 0.984）。6PBRT测试和重测的平均得分之间观察到非常强的正相关（r = 0.981）。6PBRT平均得分与握力（分别为r = 0.653，r = 0.646，右/左）、肌肉力量（肩部屈肌[分别为r = 0.793，r = 0.797，右/左]、肩部外展肌[r = 0.763，r = 0.743，右/左]、肘部屈肌[分别为r = 0.743，r = 0.755，右/左]）、平均Q-DASH得分（r = -0.555）和平均PedsQL得分（r = 0.611）之间呈现中度至强相关性。
6PBRT似乎是评估DMD患者上肢功能能力的有效且可靠的测量方法。该测试适用于能够将双手举过头顶的患者。
