Content validity of mobility measures in arthrogryposis multiplex congenita: engaging clinicians and people with lived experience.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Lower-extremity impairment is prevalent in children with Arthrogryposis multiplex congenita (AMC), frequently leading to mobility limitations. Without AMC-specific assessment tools, clinicians and researchers often employ tools that have not been formally validated for the AMC population. This study aims to establish the content validity of commonly used mobility measures in children with AMC following the COnsensus-based Standards for health Measurement INstruments (COSMIN) and the International Classification of Functioning, Disability, and Health (ICF) framework. Methods: Items from the measures "Functional Mobility Scale (FMS), Gillette Functional Assessment Questionnaire (FAQ), Functional Independence Measure for Children (WeeFIM), and Patient-Reported Outcomes Measurement Information System (PROMIS)" were linked to the ICF categories using the refined linking rules of the ICF. Three raters conducted independent linking, and inter-rater reliability was calculated using the Kappa coefficient. An expert panel consisting of people with lived experience, clinicians and researchers reviewed the ICF codes identified by the raters and evaluated the comprehensibility, relevance, and comprehensiveness of the four measures using the COSMIN standards. The Content Validity Index (CVI) and modified Kappa ( Results: Inter-rater agreement was substantial [ Conclusions: FMS, FAQ, WeeFIM, and PROMIS (Parent Proxy/Pediatric) demonstrated good content validity. However, none of these measures fully address the full spectrum of mobility experiences in children with AMC. Incorporating missing concepts, such as environmental challenges, compensatory strategies, and pain, into existing or newly developed assessment tools is essential for providing a more holistic evaluation of functional mobility. Doing so will support more comprehensive clinical assessment, improve outcome tracking, and enhance care for children living with AMC.
