Impact of Different Heel Heights on Spinal Configuration Clinical Trial
Official title:
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.
- 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.
