Brief summary

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

OTHERSpinal 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.

Design outcomes

Primary

MeasureTime frameDescription
Spinal Mobility (Range of Motion)11 monthsSppinal ROM in flexion, extension, and lateral flexions will be measured using dual inclinometers to assess the impact of each brace.

Secondary

MeasureTime frameDescription
Postural Alignment Scores via PostureScreen App11 monthsPostural alignment will be assessed using the PostureScreen mobile application. Key parameters such as head shift, shoulder asymmetry, and thoracic kyphosis will be recorded to evaluate the impact of each brace condition.
