Abstract

Purpose: To evaluate the validity and reliability of the Arch Height Index (AHI) in assessing the medial longitudinal arch (MLA) structure in children with spastic diplegic cerebral palsy (CP).

Methods: Twenty children with spastic diplegic cerebral palsy (CP), aged 5-18 years, were assessed. AHI measurements were taken in sitting and standing positions. Arch flexibility index (AFI) was calculated. Reliability was analyzed using intraclass correlation coefficients (ICC), and validity was evaluated by correlating AHI with clinical parameters.

Results: AHI measurements showed high interobserver reliability. AHI was significantly correlated with calcaneal pitch, navicular index, and Meary's angle. A lower AHI was associated with decreased gross motor function, greater hip adductor spasticity, and ankle eversion range of motion.

Conclusions: The AHI is a valid and reliable tool for assessing MLA in children with spastic diplegic CP. Lower arch height is associated with greater functional impairments.

痉挛性双瘫性脑瘫患儿足弓高度指数测量的效度和信度。

目的：评价弓高指数（AHI）在评估痉挛性脑瘫（CP）患儿内侧纵弓（MLA）结构中的效度和信度。方法：对20例5 ~ 18岁的痉挛性双瘫性脑瘫（CP）患儿进行分析。AHI测量分别在坐姿和站立位置进行。计算弓柔韧性指数（AFI）。采用类内相关系数（ICC）分析信度，通过AHI与临床参数的相关性评估效度。结果：AHI测量结果具有较高的观察者间信度。AHI与跟骨距、舟骨指数和Meary’s角有显著相关。较低的AHI与大运动功能下降、髋关节内收肌痉挛加剧和踝关节外翻活动范围有关。结论：AHI是评估痉挛性双瘫CP患儿MLA的有效和可靠的工具。弓高越低，功能损害越大。

期刊介绍： Pediatric Physical Therapy is an indexed international journal, that publishes peer reviewed research related to the practice of physical therapy for children with movement disorders. The editorial board is comprised of an international panel of researchers and clinical scholars that oversees a rigorous peer review process. The journal serves as the official journal for the pediatric physical therapy professional organizations in the Netherlands, Switzerland, New Zealand, Canada, and the United States. The journal includes articles that support evidenced based practice of physical therapy for children with neuromuscular, musculoskeletal, cardiorespiratory and developmental conditions that lead to disorders of movement, and research reports that contribute to the foundational sciences of pediatric physical therapy, ranging from biomechanics and pediatric exercise science to neurodevelopmental science. To these ends the journal publishes original research articles, systematic reviews directed to specific clinical questions that further the science of physical therapy, clinical guidelines and case reports that describe unusual conditions or cutting edge interventions with sound rationale. The journal adheres to the ethical standards of theInternational Committee of Medical Journal Editors.
