Researchers can use it as a stable balance measurement tool. Although no significant difference in somatosensory weighting was found between the two groups, somatosensory remained the primary source of feedback in postural control.</div></div>","PeriodicalId":49698,"journal":{"name":"Physical Therapy in Sport","volume":"75 ","pages":"Pages 151-157"},"PeriodicalIF":2.2,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144902373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
