Correlation Between Thoracic Kyphosis Posture and Static Balance

Study Overview
=================
Brief Summary
-----------------
The effects of balanced posture and postural changes have been evaluated in specific populations with different factors that can affect body postures and balance, such as age, musculoskeletal system, and other metabolic diseases. Studies on postural kyphosis and balance involvement are very few in the literature especially in the health population. Of the few studies that have evaluated kyphosis and balance, most are limited by small sample size and the exclusion of men. Many have focused primarily on the geriatric population. The determination that the effect of thoracic kyphosis posture on trunk biomechanical alignment may be related to balance may contribute to new treatment recommendations in this area. The aim of this study is to investigate whether the thoracic kyphosis posture has an effect on static balance.

Detailed Description
-----------------
Background: Kyphosis is roughly a slight forward curvature of the spine. A slight kyphosis or posterior curvature is normal throughout the human body and is present in every individual. Hyperkyphotic is a kyphotic angle greater than 40° commonly measured on a lateral X-ray measured by the Cobb method between C7 and T12. Postural stability or balance is the ability to keep the center of mass within the boundaries of the support base. Moving the center of mass beyond the boundaries of the support base may cause postural instability and loss of balance. There are studies showing that kyphotic posture affects the center of gravity and affects fall in the elderly, but there are limited studies on the effect of balance in young individuals. The Aim of This Study Is: To study the correlation between the balance and severity of thoracic kyphosis will be investigated

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Kyphotic Group<br>Participants with kyphosis angle ≥ 40 degrees joined the kyphosis group. FlexiCurve ruler method was used, which is a reliable tool for measuring kyphosis height and kyphosis index. In addition, it is non-invasive, inexpensive, and easy to use in a clinical setting. Static balance Assessment: Objective evaluation of the static balance evaluated by the NeuroCom Balance Manager System ® static posturography device (45 × 45 cm NeuroCom® System Version 8.1 Balance Manager International, Clackamas, Oregon, USA) | Other: FlexiCurve ruler method to assess thoracic kyphosis angle<br>* The determination that the effect of thoracic kyphosis posture on trunk biomechanical alignment may be related to balance may contribute to new treatment recommendations in this area.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Kyphosis Angle | Kyphosis angle will be measured by felxicurve ruler, normally kyphosis angle below 40 degrees recognized as normal. For participants with kyphosis angle above 40 degrees recognized as hyperkyphotic posture. FlexiCurve ruler method is valid and reliable to the gold standard. | 2 Months | 
| Static Balance Measures | NeuroCom Balance Manager System ® static posturography device to assess static balance, which is objective evaluating system. The system compare the values reported for participants assessment then compare them to pre-recorded data base. The values of the test is assessed according to the percentage to the normal (average) values matched with the age group and gender. Above 80% determined as normal, and below this value determine balance disturbance. | 2 Months |
