Impact of Different Shoe Heel Heights on Spinal Configuration During Different Phases of Menstrual Cycle
90 healthy female subjects with regular menstrual cycle ,their ages ranged from 19-25 years,their BMI ranged from 18-25 will be participated in this study.
Formetric Raster Stereography will be used to assess spinal configuration while each participant wear shoes of different heel heights 2.5 cm (low),4.5 cm (moderate) and 7 cm (height) during early follicular and mid luteal phases of menstrual cycle.

Detaljeret beskrivelse
- this study will be conducted on healthy females to investigate effect of different heel heights footwear on spine posture and pelvic position by using formetric 4 D analysis system which is a light-optical scanning method based on Video-Raster-Stereography (VRS). Accordingly, the system consists of a light projector which projects a line grid on the back of the patient which is recorded by an imaging unit. A computer software analyzes the line curvature that generates from it. the formetric provides comprehensive information about the whole body statics and posture in only one measuring process, e.g. spine curvature (lateral and frontal), vertebral rotation, and pelvic position.
- There is generally no need for reflecting markers, because the anatomical fixed points Vertebra prominens (VP), Sacrum Point (SP), Dimple Left (DL) Dimple Right (DR) as well as the spinal center line and spinal rotation are automatically detected by the system. That allows a very time-saving and reliable examination procedure.
- shoe characteristics: standard shoes will be used and designed to fit females in sizes ranging from 37-41 and different heel heights (2.5 cm low, 4,5 cm moderate and 7 cm high).
- Descriptive statistics including mean and standard deviation will be applied for dependent variables and participant demographics. repeated measures analysis of variance will be implemented to detect the difference in dependent measures among three heel condition.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
kyphotic angle
Tidsramme: from 9/2018 to 6/2019
|
this the maximum angle measured between surface tangents of the upper inflection point in the vicinity of the vertebra prominence and the thoracic lumbar inflection point
|
from 9/2018 to 6/2019
|
|
Lordotic angle
Tidsramme: from 9/2018 to 6/2019
|
this the maximum angle measured between surface tangents of the thoracic lumbar inflection point and lower lumbar-sacral inflection point
|
from 9/2018 to 6/2019
|
|
trunk imbalance
Tidsramme: from 9/2018 to 6/2019
|
trunk imbalance is defined as the lateral deviation of the vertebra prominence from the mid line dimple
|
from 9/2018 to 6/2019
|
|
trunk inclination
Tidsramme: from 9/2018 to 6/2019
|
trunk inclination refers to a difference in the height between vertebra prominence and dimple mid line based on a vertical plane (sagittal section)
|
from 9/2018 to 6/2019
|
|
pelvic tilting
Tidsramme: from 9/2018 to 6/2019
|
pelvic tilt refers as the difference in the height of the lumbar dimple based on horizontal plane ( transverse section)
|
from 9/2018 to 6/2019
|
|
pelvic inclination
Tidsramme: from 9/2018 to 6/2019
|
it is calculated as the mean torsion of the dimple left and dimple right surface normals
|
from 9/2018 to 6/2019
