Further analyses of human movement in real contexts are crucial for understanding its complex dynamics. The main objective was to identify and summarize the nonlinear measures used in data processing during out-of-laboratory assessments of human movement among healthy adolescents. Summarizing the methodological considerations was the secondary objective. The inclusion criteria were as follows: According to the Population, Concept, and Context (PCC) framework, healthy teenagers between 10 and 19 years old that reported kinetic and\/or kinematic nonlinear data-processing measurements related to human movement in non-laboratory settings were included. PRISMA-ScR was used to conduct this review. PubMed, Science Direct, the Web of Science, and Google Scholar were searched. Studies published between the inception of the database and March 2022 were included. In total, 10 of the 2572 articles met the criteria. The nonlinear measures identified included entropy (n = 8), fractal analysis (n = 3), recurrence quantification (n = 2), and the Lyapunov exponent (n = 2). In addition to walking (n = 4) and swimming (n = 2), each of the remaining studies focused on different motor tasks. Entropy measures are preferred when studying the complexity of human movement, especially multiscale entropy, with authors also carefully combining different measures, namely entropy and fractal analysis.<\/jats:p>","DOI":"10.3390\/s23010304","type":"journal-article","created":{"date-parts":[[2022,12,28]],"date-time":"2022-12-28T05:38:43Z","timestamp":1672205923000},"page":"304","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Methodological Considerations in the Kinematic and Kinetic Analysis of Human Movement among Healthy Adolescents: A Scoping Review of Nonlinear Measures in Data Processing"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4815-4896","authenticated-orcid":false,"given":"Sandra","family":"Silva","sequence":"first","affiliation":[{"name":"Escola Superior de Sa\u00fade do Vale do Ave, Cooperativa de Ensino Superior Polit\u00e9cnico e Universit\u00e1rio, Rua Jos\u00e9 Ant\u00f3nio Vidal, 81, 4760-409 Vila Nova de Famalic\u00e3o, Portugal"},{"name":"School of Health Sciences, University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"Department of Medical Sciences, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9094-1493","authenticated-orcid":false,"given":"Fernando","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"School of Health Sciences, University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"Institute of Biomedicine\u2014iBiMED, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7924-6895","authenticated-orcid":false,"given":"V\u00e2nia","family":"Figueira","sequence":"additional","affiliation":[{"name":"Escola Superior de Sa\u00fade do Vale do Ave, Cooperativa de Ensino Superior Polit\u00e9cnico e Universit\u00e1rio, Rua Jos\u00e9 Ant\u00f3nio Vidal, 81, 4760-409 Vila Nova de Famalic\u00e3o, Portugal"},{"name":"Research Centre in Physical Activity, Health and Leisure, Faculty of Sport, University of Porto, Rua Dr. Pl\u00e1cido da Costa, 91, 4200-450 Porto, Portugal"}]},{"given":"Francisco","family":"Pinho","sequence":"additional","affiliation":[{"name":"Escola Superior de Sa\u00fade do Vale do Ave, Cooperativa de Ensino Superior Polit\u00e9cnico e Universit\u00e1rio, Rua Jos\u00e9 Ant\u00f3nio Vidal, 81, 4760-409 Vila Nova de Famalic\u00e3o, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,28]]},"reference":[{"key":"ref_1","unstructured":"Bernshtein, N.A.
