The study aimed to analyze, synthesize, and investigate the measurement properties of clinical tests that assess foot posture in children and adolescents. The study included research published in scientific journals that analyzed the measurement properties of clinical tests, focusing on the validity, reliability, responsiveness, or specificity of tests for assessing foot posture in children and adolescents (ages 4 to 18 years). Studies involving children with lower limb surgery, neurological issues, or deformities, reviews, case studies, and abstracts were excluded. The search followed PRISMA guidelines on MEDLINE, EMBASE, PUBMED, CINAHL, SPORTDIscus. The methodological quality was assessed using the COSMIN and Brink and Louw tool, while the certainty of the evidence was evaluated using GRADE. Twelve studies were included in this systematic review, evaluating the following clinical tests: foot posture index-6, normalized truncated navicular height, Staheli index, plantar arch index, arch height index, navicular drop, resting and neutral calcaneal stance position, pediatric flat foot proforma, subjective perception of the height of the feet arch and Clarke angle. Current clinical tests predominantly prioritize the examination of intra- and inter-rater reliability. Conversely, validity has only been found in restricted studies, and responsiveness has not been assessed. No evidence supports high-quality measurement properties for clinical tests evaluating foot posture in children and adolescents. [ABSTRACT FROM AUTHOR]

Background: The Activity Scale for Kids (ASK) assesses the physical disability of children (5 to 15 years old) with neurological, orthopaedic or rheumatic diseases. The objective of this study was to translate and cross‐culturally adapt the ASK for Brazilian Portuguese and assess the validity and reliability of the instrument. Methods: A total of 67 children and adolescents with musculoskeletal, neurological or rheumatic diseases participated in the study. We evaluated the comprehension of the pre‐final version of the questionnaire in 24 participants and reliability and validity in the other 43 participants. The translation and adaptation of ASK to Brazilian Portuguese followed guidelines from previous studies. The validity of the Brazilian Portuguese version of the ASK was verified through Spearman's correlation with the Pediatric Quality of Life Inventory™ Version 4.0 (PedQL). Intraclass correlation coefficient verified inter‐ and intra‐evaluator reliability, while internal consistency was assessed using Cronbach's alpha. Scores were used to assess the standard error of the mean and minimal detectable change. Results: The Brazilian Portuguese version of the ASK presented excellent reliability, internal consistency, agreement and moderate correlation with PedsQL (0.522, P < 0.001) between ASK performance and PedsQL; 0.537, P < 0.001 between ASK capacity and PedsQL. Conclusion: The Brazilian Portuguese version of the ASK has good validity and reliability and may be used by professionals and researchers to assess the functioning of children and adolescents with disabilities.
