Checking if the Postural Habits and Awareness Scale (PHAS) works well for people with postural hyperkyphosis.

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

Observational Istanbul University - Cerrahpasa · NCT06907901

This project will test whether the Postural Habits and Awareness Scale (PHAS) gives consistent results for people aged 8 to 65 with postural hyperkyphosis.

What this trial studies

This observational, cross-sectional project will enroll 128 participants diagnosed with postural hyperkyphosis who can complete questionnaires. Participants will complete the PHAS and the Kyphosis-Specific Spinal Appearance Questionnaire (KSSA), and the PHAS will be re-administered after two weeks to measure test-retest stability. Standard psychometric analyses will be used to examine internal consistency, test-retest reliability, and concurrent validity between PHAS and KSSA. The goal is to determine whether PHAS produces stable, reliable scores suitable for clinical use and future rehabilitation studies.

Who should consider this trial

Good fit: Ideal participants are people aged 8–65 with clinician- and radiograph-confirmed postural hyperkyphosis (Cobb angle ≥ 50°) who can complete questionnaires independently.

Not a fit: Patients with other spinal deformities, inflammatory spinal disease, recent postural rehabilitation, functional limitations from acute or chronic pain, or cognitive impairments preventing independent questionnaire completion are unlikely to benefit from this work.

Why it matters

Potential benefit: If PHAS proves reliable, clinicians could use it to track postural awareness and guide rehabilitation for patients with hyperkyphosis.

How similar studies have performed: Psychometric testing and kyphosis-specific questionnaires exist, but PHAS itself is novel and its reliability in hyperkyphosis patients has not yet been confirmed.
