Reliability of PHAS in Postural Hyperkyphosis

Reliability Analysis of the Postural Habits and Awareness Scale (PHAS) in Patients With Postural Hyperkyphosis

Sponsor

Istanbul University - Cerrahpasa

Enrollment

128 participants

Start Date

Jun 1, 2025

Study Type

OBSERVATIONAL

Conditions

Spine Postural Kyphosis Assessment, Self

Summary

This observational, cross-sectional study aims to evaluate the reliability of the Postural Habits and Awareness Scale (PHAS) in patients with postural hyperkyphosis. The PHAS is designed to assess individuals' postural awareness and habits through four subscales. A total of 128 participants diagnosed with postural hyperkyphosis will complete the PHAS and the Kyphosis-Specific Spinal Appearance Questionnaire (KSSA). Test-retest reliability will be assessed by reapplying the PHAS after two weeks. Internal consistency, test-retest reliability, and concurrent validity will be analyzed. The study aims to provide a valid and reliable tool for evaluating postural awareness in clinical practice and future rehabilitation studies.
