We examined the anthropometric parameters in a non-clinical setting. Descriptive statistics were used to characterize the data. To explore potential differences across the variables, we utilized Bonferroni-corrected Welch\u2019s 2-sample t-tests, one-way analysis of means, and univariable linear regression.Results:\u00a0We analyzed the associations between the variables and the anthropometric parameters in 501 TDC, aged 6 to 17 years. We found a statistically significant, but not clinically meaningful decrease in ROM for the hip, knee, and ankle as well as decreased femoral anteversion and increased tibial torsion with increasing age, but no association with sex or sidedness. However, several associations between BMI and ROM measurements were statistically significant and potentially clinically meaningful, with ROM decreasing by approximately 0.4\u00b0 to 1.2\u00b0 per unit increase in BMI, particularly for hip, knee, and ankle flexion movements.Conclusion:\u00a0Anthropometric parameters remain clinically stable after 7 years of age and are affected only by the BMI but not sex or age. We found a statistically significant but not clinically relevant decrease in torsion and joint ROM with increasing age.<\/jats:p>","DOI":"10.2340\/17453674.2025.43478","type":"journal-article","created":{"date-parts":[[2025,5,5]],"date-time":"2025-05-05T11:29:55Z","timestamp":1746444595000},"source":"Crossref","is-referenced-by-count":2,"title":["Angular alignment, rotational profile, and joint range of motion in the lower limb of typically developing children from 7\u201316 years of age: a cross-sectional study"],"prefix":"10.2340","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3201-5827","authenticated-orcid":false,"given":"Christian","family":"Wong","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2324-6420","authenticated-orcid":false,"given":"Michael M\u00f8rk","family":"Petersen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trine","family":"Henriksen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ales","family":"Jurca","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soeren","family":"Boedtker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Balslev-Clausen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steen","family":"Harsted","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1183","published-online":{"date-parts":[[2025,5,1]]},"reference":[{"key":"108853","doi-asserted-by":"crossref","unstructured":"Staheli L, Corbett M, Wyss C, King H.
