Evaluation of Vestibular Dysfunction or Visuospatial Perception in Individuals With Idiopathic Scoliosis

• Conditions: Visuospatial/Perceptual Abilities; Vestibular Function Disorder; Scoliosis Idiopathic
• Interventions: Other: Balance assessment; Other: Unterberger test; Other: Corsi Block Tapping (mobıl app); Other: Navigation performance; Other: Cobb angle measurement; Other: Scolio Detector (mobıl app)

• Registration Number: NCT05045014
• Lead Sponsor: Inonu University

Brief Summary

This study was planned to investigate whether there is a visual-spatial perception disorder in individuals with idiopathic scoliosis and also to reveal its dependent/independent relationship with vestibular dysfunction.

Detailed Description

Vestibular dysfunction is thought to be associated with the etiology of patients with idiopathic scoliosis. However, there is limited data on this in the literature. However, visuospatial ability has been evaluated in the literature regarding vestibular dysfunction independent of scoliosis. In the study, it was first requested to investigate vestibular dysfunction in patients with scoliosis. However, as far as is known, there is no study in the literature on visuospatial perception investigated for vestibular dysfunction in patients with scoliosis. This study was planned to investigate whether there is a disorder related to visuospatial perception and to reveal its dependent/independent relationship with vestibular dysfunction. Based on the studies, it is planned to evaluate visuospatial (visual-spatial) perception performance in the presence/absence of vestibular dysfunction in individuals with idiopathic scoliosis. The hypothesis of the study is that vestibular function and related visual-spatial perception may be affected in individuals with idiopathic scoliosis.

Arm && Interventions

Group	Intervention	Description
Patient group	Unterberger test	Romberg test and single leg standing test will be used in balance assessment. The presence of vestibular dysfunction will be evaluated with the Utenberger test. Under the name of visual-spatial perception, spatial memory will be evaluated with the mobile application called Corsi Block Tapping, and navigation performance will be evaluated with the triangle completion task. In addition, X-ray images taken during routine follow-ups will be used to determine the location, type of curvature and Cobb angle of the scoliosis. The degree of rotation will be measured with a mobile application called Scoliodetector. Quality of life is planned to be evaluated with the Scoliosis Research Society-22 questionnaire.
Control group	Unterberger test	Romberg test and single leg standing test will be used in balance assessment. The presence of vestibular dysfunction will be evaluated with the Utenberger test. Under the name of visual-spatial perception, spatial memory will be evaluated with the mobile application called Corsi Block Tapping, and navigation performance will be evaluated with the triangle completion task.
