Official title
The Effect of Different Hyperextension Braces on Spinal Mobility
Overview
This project aims to investigate the effects of different hyperextension braces (Jewett and Spinomed) on spinal mobility and posture. Hyperextension braces are commonly prescribed to limit spinal flexion and regulate load distribution, especially in cases of spinal injuries and postural disorders. However, their objective impact on spinal biomechanics remains unclear. Purpose and Scope The study will be conducted on 30 healthy participants aged 18-35. Spinal mobility, posture, and movement analysis will be assessed using a dual inclinometer and the PostureScreen mobile application. Evaluations will be performed under three conditions: * Without a brace * With a Jewett brace * With a Spinomed brace (applied in randomized order) Assessments will include four-direction spinal mobility and postural analysis during daily life activities such as standing, squatting, and single-leg stance. Hypotheses H0: Hyperextension braces do not restrict spinal mobility. H1: Hyperextension braces restrict spinal mobility. H2: Hyperextension braces do not alter body alignment during movements. H3: Hyperextension braces alter body alignment during movements. Methodology The study is designed as a cross-sectional trial. Each measurement will be repeated three times. Data will be analyzed statistically using ANOVA or Kruskal-Wallis tests depending on distribution. Ethical approval has been obtained (Yalova University, Protocol No: 2024/4). Expected Contributions Academic: Results are expected to be presented at the Congress of the International Society of Biomechanics (2025) and published in a high-impact Q1 journal such as Spine. Clinical: Findings will provide objective data on the effectiveness of hyperextension braces, guiding clinicians and physiotherapists in brace selection. Educational: The project will also contribute to the training of young researchers, offering hands-on experience in research design and execution
Interventions
- Other Spinal hyperextension brace
The Jewett brace is a hyperextension spinal orthosis designed to limit spinal flexion and promote proper posture by applying anterior and posterior forces to the thoracolumbar spine. It is commonly used for spinal fractures, postural disorders, and to reduce spinal load. Participants will wear the Jewett brace during the intervention phase, and spinal mobility and posture will be assessed.
Primary outcome measures
- Spinal Mobility (Range of Motion) [Time frame: 11 months]
Secondary outcome measures (1)
- Postural Alignment Scores via PostureScreen App [Time frame: 11 months]
