Abstract

Purpose: Manual anthropometric evaluations of pediatric lower extremities are essential in orthopedic pediatric practice due to their noninvasive and time-feasible nature. Therefore, this study aims to assess the test-retest reliability of clinical measurements obtained on children to examine measurement stability over time.

Methods: In a test-retest design, data were collected from 50 Danish school children with 5-to 6 weeks between sessions. Measurements encompassed the joint range of motion (ROM), rotational profile, and angular alignment of lower extremities for a representative sample of school children. Reliability was assessed using intraclass correlations (ICC), and agreement was assessed using limits of agreement (LoA) and precision.

Results: Reliability analysis revealed excellent results for foot length (ICC > 0.9), good results for foot width (ICC < 0.9), and poor to moderate results for all other measurements (ICC < 0.5, ICC < 0.75). Agreement results for hallux valgus were acceptable (within established reference) and the remaining variables were not acceptable (outside established reference).

Conclusions: The majority of the manual assessment procedures were found to have poor reliability. This study highlights the need for reliable and time-efficient tools to assist clinicians in assessing manual clinical measurements and future research should explore this.

Level of evidence: Level III.

儿童下肢关节运动和对齐临床测量的测试-再测试可靠性。

目的：小儿下肢的手工人体测量评估是必不可少的矫形儿科实践，由于其无创和时间可行的性质。因此，本研究旨在评估儿童临床测量的重测信度，以检验测量随时间的稳定性。方法：采用重测设计，从50名丹麦学龄儿童中收集数据，每组间隔5- 6周。测量包括关节活动范围（ROM）、旋转轮廓和下肢的角度对齐，以学校儿童为代表性样本。使用类内相关性（ICC）评估可靠性，使用一致性限（LoA）和精度评估一致性。结果：信度分析显示，脚长（ICC > 0.9）结果良好，脚宽（ICC）结果良好。结论：大多数人工评估程序的信度较差。这项研究强调需要可靠和高效的工具来帮助临床医生评估人工临床测量，未来的研究应该探索这一点。证据等级：三级。

期刊介绍： Aims & Scope The Journal of Children’s Orthopaedics is the official journal of the European Paediatric Orthopaedic Society (EPOS) and is published by The British Editorial Society of Bone & Joint Surgery. It provides a forum for the advancement of the knowledge and education in paediatric orthopaedics and traumatology across geographical borders. It advocates an increased worldwide involvement in preventing and treating musculoskeletal diseases in children and adolescents. The journal publishes high quality, peer-reviewed articles that focus on clinical practice, diagnosis and treatment of disorders unique to paediatric orthopaedics, as well as on basic and applied research. It aims to help physicians stay abreast of the latest and ever-changing developments in the field of paediatric orthopaedics and traumatology. The journal welcomes original contributions submitted exclusively for review to the journal. This continuously published online journal is fully open access and will publish one print issue each year to coincide with the EPOS Annual Congress, featuring the meeting’s abstracts.
