Is this trial a fit for you?

Likely a good fit

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

Probably 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.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

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