OBJECTIVE: This study aimed to compare the occurrence of asymmetry or muscle tone disorders in the first year of life in adolescents with IS and their healthy counterparts. METHODS: The parents of adolescents with IS and without scoliosis completed a survey on the occurrence of asymmetry, abnormal muscle tone, and physiotherapy in their children in the first year of life. Pearson\u2019s chi square test and Cramer\u2019s coefficient were used. RESULTS: The final analysis included 527 surveys completed by parents of adolescents with idiopathic scoliosis (150) and without scoliosis (377). A significantly higher frequency of asymmetry (p= 0.001) and muscle tone disorders (p= 0.001) was noted in adolescents with idiopathic scoliosis. The results also revealed a significant association between scoliosis and asymmetry (p= 0.001), as well as muscle tone (p= 0.001). CONCLUSIONS: Developmental asymmetry or improper muscle tone in the first year of life could be considered a potential factor in the development of scoliosis; however, this hypothesis should be confirmed in future studies. Infants diagnosed with developmental disorders require systematic observation.<\/jats:p>","DOI":"10.3233\/bmr-171075","type":"journal-article","created":{"date-parts":[[2022,4,12]],"date-time":"2022-04-12T12:41:06Z","timestamp":1649767266000},"page":"1003-1011","source":"Crossref","is-referenced-by-count":3,"title":["Analysis
