Abstract

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.

Methods: 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.

Results: 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).

Discussion: 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.

Trial registration: NCT06174025.

杜氏肌营养不良患者6分钟钉板和环试验的效度和信度。

简介/目的：评估杜氏肌营养不良症（DMD）患者上肢（UE）功能能力的试验是有限的。本研究旨在评估6分钟钉板和环测试（6PBRT）作为一种实用工具的有效性和可靠性。方法：使用6PBRT评估DMD儿童（n = 22）的UE功能能力，手臂，肩膀和手的快速残疾（Q-DASH）评估功能，儿科生活质量量表（PedsQL）评估生活质量，以及握力和UE肌肉力量测力仪评估DMD儿童（n = 22）。结果：6PBRT具有良好的重测信度，类内相关系数（ICC）为0.978（95%可信区间为0.946 ~ 0.984）。6PBRT平均评分与复测6PBRT平均评分呈正相关（r = 0.981）。平均6PBRT评分与握力（r = 0.653, r = 0.646，右/左）、肌肉力量（肩屈肌[r = 0.793, r = 0.797，右/左]、肩外展肌[r = 0.763, r = 0.743，右/左]、肘屈肌[r = 0.743, r = 0.755，右/左]）、Q-DASH平均评分（r = -0.555）、PedsQL平均评分（r = 0.611）具有中强相关性。讨论：6PBRT似乎是评估DMD患者上肢功能能力的有效和可靠的测量方法。这项测试适用于能够将双手举过头顶的患者。试验注册：NCT06174025。

期刊介绍： Muscle & Nerve is an international and interdisciplinary publication of original contributions, in both health and disease, concerning studies of the muscle, the neuromuscular junction, the peripheral motor, sensory and autonomic neurons, and the central nervous system where the behavior of the peripheral nervous system is clarified. Appearing monthly, Muscle & Nerve publishes clinical studies and clinically relevant research reports in the fields of anatomy, biochemistry, cell biology, electrophysiology and electrodiagnosis, epidemiology, genetics, immunology, pathology, pharmacology, physiology, toxicology, and virology. The Journal welcomes articles and reports on basic clinical electrophysiology and electrodiagnosis. We expedite some papers dealing with timely topics to keep up with the fast-moving pace of science, based on the referees'' recommendation.
