Posture and Mobility Measurements of the Upper Quadrant in Asymptomatic Subjects by Means of a Smartphone

Study Overview
=================
Brief Summary
-----------------
This study aims to investigate posture-mobility associations in the upper quadrant by means of smartphone measurements

Detailed Description
-----------------
One purpose of this study is to measure the magnitude of the thoracic kyphosis, thoracic spine extension, and side-to-side differences in scapular protraction and elbow extension range of motion during the median nerve neurodynamic test through a smartphone (iPhone 4, app Compass, iOS 7.1.1), and to assess the intrarater agreement parameters. Another purpose is to assess associations between thoracic kyphosis, thoracic spine extension, scapular protraction and the resting length of the pectoralis minor muscle through smartphone, photographs and tape measurements.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Elbow extension range of motion | Elbow extension range of motion (in degrees) during the median nerve neurodynamic test is measured by means of a smartphone (iPhone 4, app Compass, iOS 7.1.1) | At the time of the assessment | 
| Thoracic kyphosis orientation | The magnitude of the thoracic kyphosis (in degrees) in the standing upright position is measured by means of a smartphone (iPhone 4, app Compass, iOS 7.1.1) | At the time of the assessment | 
| Thoracic spine extension range of motion | The extension range of motion of the thoracic spine (in degrees) in the standing upright position is measured by means of a smartphone (iPhone 4, app Compass, iOS 7.1.1) | At the time of the assessment | 
| Scapular protraction orientation | The magnitude of the scapular protraction (in degrees) in the standing upright position with the arms at rest is measured by means of a smartphone (iPhone 4, app Compass, iOS 7.1.1) | At the time of the assessment | 
| Pectoralis minor muscle resting length | Pectoralis minor muscle resting length (in centimeters) with the arms at rest is measured by means of a measuring tape in the standing upright position | At the time of the assessment | 
| Thoracic kyphosis orientation | The magnitude of the thoracic kyphosis (in degrees) in the standing upright position is measured on digital photographs by means of a computer software | At the time of the assessment | 
| Thoracic spine extension range of motion | The extension range of motion of the thoracic spine (in degrees) in the standing upright position is measured on digital photographs by means of a computer software | At the time of the assessment |
