简要总结
The goal of this cross-sectional study is to evaluate the immediate effect of heels elevation on the spine posture in a group of 100 healthy subjects (50 males, 50 females). The main question it aims to answer is weather high heels immediately affects spinal posture and pelvic position in the sagittal plane.
Participants will undergo an elevation of 3cm and then 7cm of both heels, while their spine posture will be examined by means of a rasterstereography device.
详细描述
The data collected by the rasterstereography device will be:
- pelvic tilt angle (PI), the angle determined by the vertical and the tangent to lumbosacral junction (ILS);
- ITL-ILS lordotic angle, measured between the tangents of the thoracolumbar junction (ITL) and the lumbosacral junction (ILS);
- ICT-ITL kyphotic angle, measured between the tangents of the cervicothoracic junction (ICT) and the thoracolumbar junction (ITL); see fig. 1;
- lumbar arrow (FL) horizontal distance in millimeters from the vertical line that passes through the kyphotic apex in the lumbar spine;
- cervical arrow (FC) (horizontal distance in millimeters from the virtual vertical plumb line that passes through the kyphotic apex in the cervical spine);
- antero-posterior flexion of the trunk (Trunk Inclination-TI) measured as the angle between the vertical line and the line passing through the prominent cervical vertebra (VP) to the line connecting the two dimples (DM); see fig. 2.
Participants will provide information on age, height and weight. A questionnaire will be administered to standardize the types of high-heeled shoes used and to verify their frequency of use.
Evaluation Protocol
- sample 1: barefoot neutral position;
- sample 2: barefoot neutral position;
- sample 3: 3 cm rise under both heels;
- sample 4: 7 cm rise under both heels.
