Abstract

Aim

To develop a new tool for identifying joint hypermobility of the paediatric foot and ankle, based on a dichotomous scoring system utilising the Lower Limb Assessment Score (LLAS), to separate the foot and ankle items.

Material and methods

A total of 205 children, aged between 5 and 10 years, participated in a cross-sectional study. The new tool Foot and Ankle Flexibility Index (FAFI) was predicated upon the last 7 items of LLAS, which are specific to the foot and ankle. The internal consistency was measured with Cronbach's test. Kappa statistics with 95% CI were calculated to verify the level of inter-rater and intra-rater agreement for the FAFI.

Results

Cronbach's alpha returned 0.82. The correlations between items returned a mean of 0.59 (range: 0.43–0.74). The discrimination score on the ROC curve (4 points) showed that the model can be used to identify children with joint hypermobility of the foot and ankle. Inter-rater reliability was largely good (ICC = 0.89). Excellent intra-rater reliability was found (ICC = 0.96)

Conclusions

This study identified high reliability between evaluators, and high sensitivity and specificity, for a new reliable and valid tool for the identification of foot and ankle joint hypermobility.

足踝灵活性指数（FAFI）的开发、验证和心理测量分析

材料和方法共有 205 名 5 至 10 岁的儿童参加了一项横断面研究。新工具 "足踝灵活性指数"（FAFI）是根据下肢活动能力评分（LLAS）的最后 7 个项目设计的，这些项目专门针对足踝。内部一致性采用 Cronbach 检验进行测量。计算了带有 95% CI 的 Kappa 统计量，以验证评分者之间和评分者内部对 FAFI 的一致性水平。项目间相关性的平均值为 0.59（范围：0.43-0.74）。ROC曲线上的区分度得分（4分）表明，该模型可用于识别患有足踝关节活动过度症的儿童。评分者之间的可靠性基本良好（ICC = 0.89）。结论这项研究发现，评估者之间的可靠性很高，灵敏度和特异性也很高，是鉴定足踝关节活动过度的可靠有效的新工具。

期刊介绍： The Journal of Tissue Viability is the official publication of the Tissue Viability Society and is a quarterly journal concerned with all aspects of the occurrence and treatment of wounds, ulcers and pressure sores including patient care, pain, nutrition, wound healing, research, prevention, mobility, social problems and management. The Journal particularly encourages papers covering skin and skin wounds but will consider articles that discuss injury in any tissue. Articles that stress the multi-professional nature of tissue viability are especially welcome. We seek to encourage new authors as well as well-established contributors to the field - one aim of the journal is to enable all participants in tissue viability to share information with colleagues.
