QUESTION
What is the intra and inter-rater reliability and concurrent validity of the weight-bearing lunge test within a Congenital Talipes Equinovarus population?
DESIGN
Test retest design for reliability and validity. The measure was taken, following preconditioning of the participants, using distance from wall, angle at distal posterior tibia using a digital inclinometer and the iPhone level function, twice by each rater. The raters included a clinician, clinician in training and a parent/carer.
OUTCOME MEASURES
Weight bearing lunge test as a measure of ankle dorsiflexion.
RESULTS
Twelve children aged 5-10 years were eligible to participate and consented, along with their parents. Intra-reliability of distance measures for all raters were good to excellent (ICC clinician 0.95, ICC training clinician 0.98 and ICC parent 0.89). Intra-rater reliability of the iPhone for all raters was good (ICCs > 0.751) and good to excellent for the inclinometer (ICC clinician 0.87, ICC training clinician 0.90). Concurrent validity between the clinician's and parents distance measure was also high with ICC of 0.899. Inter-rater reliability was excellent for distance measure (ICC = 0.948), good for the inclinometer (ICC = 0.801) and moderate for the iPhone (ICC = 0.68). Standard error of measurement ranged from 0.70-2.05, whilst the minimal detectable change ranged from 1.90-5.70.
CONCLUSION
The use of the WBLT within this CTEV population has demonstrated good to excellent reliability and validity amongst clinicians, clinicians in training and parents/carers, supporting its use as an assessment measure of dorsiflexion range of motion. There is support for parents/carers to use the WBLT at home as a monitoring assessment measure which may assist with early detection of a relapse.

问题
在先天性马蹄内翻足人群中，负重弓步试验的评分者内信度、评分者间信度及同时效度如何？
设计
用于信度和效度的重测设计。在对参与者进行预处理后，由每位评分者使用到墙壁的距离、用数字倾角仪测量的胫骨远端后侧角度以及iPhone的水平功能进行两次测量。评分者包括一名临床医生、一名实习临床医生和一名家长/照顾者。
观察指标
负重弓步试验作为踝关节背屈的一项测量指标。
结果
12名5至10岁的儿童及其家长符合条件并同意参与。所有评分者对距离测量的评分者内信度良好至优秀（临床医生的组内相关系数ICC为0.95，实习临床医生为0.98，家长为0.89）。所有评分者使用iPhone的评分者内信度良好（ICC>0.751），使用倾角仪的评分者内信度良好至优秀（临床医生的ICC为0.87，实习临床医生为0.90）。临床医生和家长的距离测量之间的同时效度也很高，ICC为0.899。评分者间距离测量的信度优秀（ICC = 0.948），倾角仪测量的信度良好（ICC = 0.801），iPhone测量的信度中等（ICC = 0.68）。测量的标准误范围为0.70 - 2.05，而最小可检测变化范围为1.90 - 5.70。
结论
在该先天性马蹄内翻足人群中使用负重弓步试验，在临床医生、实习临床医生以及家长/照顾者中显示出良好至优秀的信度和效度，支持将其用作背屈活动范围的评估指标。支持家长/照顾者在家中使用负重弓步试验作为监测评估指标，这可能有助于早期发现复发情况。
