An observational study in Joint Hypermobility, Adolescent Idiopathic Scoliosis and Foot Posture, sponsored by Istinye University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 10 Years to 19 Years. Per ClinicalTrials.gov, last updated 2026-06-26.
Sponsored by Istinye University · Observational
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.

The study population consists of adolescents aged 10 to 19 years who have been clinically and radiographically diagnosed with Adolescent Idiopathic Scoliosis. Participants must have a Cobb angle of at least 10° and be able to complete physical assessments, including hypermobility and foot posture evaluations.

Exclusion Criteria:
Participants diagnosed with Adolescent Idiopathic Scoliosis will undergo assessments of hypermobility (Beighton Score), foot posture (Foot Posture Index), and scoliosis severity (Cobb angle).
Other: Assessment
Participants diagnosed with Adolescent Idiopathic Scoliosis will undergo assessments of hypermobility (Beighton Score), foot posture (Foot Posture Index), and scoliosis severity (Cobb angle).
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.
Time frame: 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.
Time frame: 4 weeks
Feiss Line Test
Used to evaluate the structural characteristics of the arch of the foot. In this test, the position of the navicular tubercle above or below a line drawn by aligning the medial malleolus, navicular tubercle, and first metatarsal head indicates the presence of pes planus or pes cavus.
Time frame: 4 weeks
Sit-Reach Test
This is a common field test that evaluates the flexibility of the hamstring and lumbar muscles. The participant sits in a straight position, knees straight, and the soles of their feet touching the test box, reaching forward; the distance between their toes indicates the level of flexibility.
Time frame: 4 weeks

Ran from Dec 2025 to primary completion in Mar 2026, 3 months.
Of 22 observational studies under Joint Instability, half reached primary completion within 7 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 35. This study's 3 months is below that.
