During SP, the participant kept the upright stance for 30 s while an optoelectronic system with reflective markers recorded feet position and body sway, and two force plates measured the Center of Pressure (CoP) displacement and Ground Reaction Force (GRF) of each foot. During GI, the participant stood on the force plates for at least 10 s and then spontaneously started walking, while optoelectronic system was used to monitor heel-off events; wireless EMG probes recorded the anticipatory postural adjustments (APAs) in trunk and lower limb muscles.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Compared to shod condition, during barefoot SP the participant showed a reduced anteroposterior (AP) and mediolateral (ML) extension of the Base of Support (BoS), and the whole-body CoP shifted about 7 mm more anteriorly, approaching the \u201csafer\u201d geometric center of the BoS. Despite this difference, the AP and ML ranges of CoP oscillations were similar in both conditions. In GI, the trunk dorsal muscles showed different APA patterns: when barefoot they were excitatory in the trailing and inhibitory in the leading side while they were bilaterally inhibitory when shod.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>In parallel to CoP shift toward a \u201csafer\u201d position in SP, in barefoot GI the body rotation toward the trailing side may reveal a more \u201ccautious\u201d approach; this also shows that different postural strategies may be adopted in GI by one and the same individual.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnhum.2024.1463249","type":"journal-article","created":{"date-parts":[[2024,9,26]],"date-time":"2024-09-26T04:27:57Z","timestamp":1727324877000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Case report: New perspectives on gait initiation strategies from a case of full toes amputation in a professional mountain climber"],"prefix":"10.3389","volume":"18","author":[{"given":"Jorge L.","family":"Storniolo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronica","family":"Farinelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mattia","family":"Onesti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"Correale","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonardo A.","family":"Peyr\u00e9-Tartaruga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Esposti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Cavallari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,9,26]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"574","DOI":"10.1016\/j.gaitpost.2014.11.017","article-title":"Evaluation of toddler different strategies during the first six-months of independent walking: A longitudinal study.","volume":"41","author":"Bisi","year":"2015","journal-title":"Gait Post."},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.3390\/s22114150","article-title":"Fundamental concepts of bipolar and high-density surface EMG understanding and teaching for clinical, occupational, and sport applications: Origin, detection, and main errors.","volume":"22","author":"Campanini","year":"2022","journal-title":"Sensors"},{"key":"B3","doi-asserted-by":"publisher","first-page":"549","DOI":"10.1002\/jor.20661","article-title":"The role of the great toe in balance performance.","volume":"27","author":"Chou","year":"2009","journal-title":"J.
