Brief 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.

Hyperkyphosis; Postural Habits; Postural Awareness; Psychometric Analysis; Spinal Deformity; Postural Evaluation

Outcome Measures

Primary Outcomes (1)

• Reliability of the Postural Habits and Awareness Scale (PHAS)

  Internal consistency will be evaluated using Cronbach's Alpha. Test-retest reliability will be assessed by calculating the Intraclass Correlation Coefficient (ICC) between two PHAS administrations. The PHAS consists of 19 items, each scored on a 5-point Likert scale (total score range: 19 to 95). Higher scores indicate better postural habits and awareness. Higher ICC values indicate better reliability.

  2 weeks

Secondary Outcomes (1)

• Kyphosis-Specific Spinal Appearance Questionnaire (KSSAQ)

  Baseline

Study Arms (1)

Hyperkyphosis Group

Participants diagnosed with postural hyperkyphosis completing the PHAS and KSSA for reliability analysis.

Behavioral: PHAS Assessment

Interventions

PHAS Assessment BEHAVIORAL

Participants will complete the Postural Habits and Awareness Scale (PHAS) to assess postural awareness and habits. The scale will be administered twice, two weeks apart, to evaluate reliability.

Hyperkyphosis Group

Eligibility Criteria

• Age: 8 Years - 65 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The study population consists of individuals diagnosed with postural hyperkyphosis. Participants will include patients aged 8 to 65 years who have been clinically and radiologically confirmed to have postural hyperkyphosis with a Cobb angle of 50° or higher. All participants are expected to be capable of performing daily activities independently.

You may qualify if:

• Age between 8 and 65 years
• Diagnosed with postural hyperkyphosis (Cobb angle ≥ 50° confirmed by clinical and radiological evaluation)
• Ability to perform daily activities independently
• Voluntary participation and signed informed consent

You may not qualify if:

• Presence of scoliosis or other spinal deformities
• Kyphosis due to severe osteoporosis or pathological fractures
• Diagnosis of ankylosing spondylitis or other inflammatory spinal diseases
• Functional limitations due to acute or chronic pain
• Previous postural awareness training or spinal rehabilitation within the last 6 months
• Cognitive impairment or severe psychiatric disorder preventing independent questionnaire completion
