Brief Summary

Adolescent Idiopathic Scoliosis is a three-dimensional spinal deformity that may also affect joint mobility, lower limb alignment, and overall posture. Joint hypermobility and foot posture abnormalities, including pronation or supination, are commonly observed in adolescents and may contribute to postural imbalance or altered biomechanical loading. However, the relationship between hypermobility, foot posture, and the severity of scoliosis remains unclear. The aim of this study is to examine whether generalized joint hypermobility and foot posture characteristics are associated with Cobb angle severity in adolescents diagnosed with Adolescent Idiopathic Scoliosis. Hypermobility will be assessed using the Beighton Score, and foot posture will be evaluated with the Foot Posture Index. Understanding these associations may help clinicians better evaluate biomechanical factors related to scoliosis and guide future preventive or therapeutic approaches.

Outcome Measures

Primary Outcomes (2)

• Foot Posture Index-6

  The Foot Posture Index-6 is a reliable and valid clinical assessment tool used to objectively evaluate foot posture in the pronation-supination spectrum. The assessment is performed with the individual in a relaxed standing position and is based on six observational criteria. The total score ranges from -12 to +12, where higher scores indicate a more pronated foot posture, while lower scores reflect a more supinated posture. A score close to 0 represents a neutral foot posture.

  4 weeks

• The Beighton Test

  This is a standardized and easily applicable clinical assessment method used to determine joint hypermobility. The total score for the nine-item test ranges from 0 to 9. A total score of ≥4 indicates the presence of hypermobility. It is scored out of 9 points; each positive finding is evaluated as 1 point.
