Verticality perception reveals a vestibular deficit in adolescents with idiopathic scoliosis.

Adolescent idiopathic scoliosis (AIS) is a three-dimensional spine deformation with elusive aetiopathogenesis. One appealing hypothesis points to its neurologic origin with an emphasis on a vestibular impairment. In the present study, we explored the hypothesis of a vestibular deficit accompanying AIS by assessing differences in the subjective estimation of the gravitational vertical between adolescents with idiopathic scoliosis (n = 10, age 11-16 years, Cobb's angle > 15°) and healthy age-matched controls (n = 10).
