\nRecent studies have revealed that in many cases of adolescent idiopathic scoliosis (AIS)<\/strong> there are alterations in vestibular function:<\/p>
\n
\nOtolith dysfunctions<\/strong> (especially of the utricle and saccule), which compromise the perception of verticality.<\/p>
\n
\nAsymmetries in vestibulo-spinal integration<\/strong>, which can influence postural tone and the symmetrical organization of the body in space.<\/p>
\n
\nIn animal models, unilateral vestibular lesions during development generate spinal curvatures, even without external mechanical intervention.<\/p>

\nMany adolescents with scoliosis also have a history of:<\/p>
\n\r\n
\n- Motion sickness in childhood.<\/li>
\n<\/ul>\r\n\r\n
\n- Clumsiness or delays in motor milestones.<\/li>
\n<\/ul>\r\n\r\n
\n- Difficulties with coordination and balance.<\/li>
\n<\/ul>\r\n\r\n
\n- Spatial disorientation.<\/li>
\n<\/ul>\r\n\r\n
\n- Poor adaptation to postural changes.<\/li>
\n<\/ul>\r\n
\n
And yet, their vestibular system is never evaluated.<\/strong><\/p>
\n
\nWhat can you explore as a clinician?<\/strong><\/h2>
\n\r\n
\n- Tests for subjective visual vertical (SVV) perception.<\/li>
\n<\/ul>\r\n\r\n
\n- Static and dynamic balance tests under varied sensory conditions.<\/li>
\n<\/ul>\r\n\r\n
\n- Reaction to rotational movement.<\/li>
\n<\/ul>\r\n\r\n
\n- Observation of postural control.<\/li>
\n<\/ul>\r\n\r\n
\n- Sensory and early developmental history (motion sickness, tone, milestones, fine motor skills).<\/li>
\n<\/ul>\r\n
\n
And what if scoliosis were not only \u201cstructural\u201d?<\/strong><\/h2>
\n
\nAn underdeveloped otolithic system can compromise the body\u2019s spatial organization.
The spine does not twist by chance<\/strong> \u2014 it twists because the body is misorganized in relation to gravity.<\/strong>
If the vestibular system does not provide a clear and symmetrical signal, the body seeks adaptations\u2026 and scoliosis may be one of them.<\/p>
\n
\nAnd you?<\/strong><\/p>
\n\r\n
\n- Do you include vestibular assessment in your scoliosis evaluation?<\/li>
