Study Overview
Brief Summary
Dysmenorrhea comes from the Greek word for difficult monthly flow and describes painful menstruation.Primary dysmenorrhea might be caused by spinal misalignment and incompatibility between muscles of the pelvic circumference and soft tissue.Leg Length Discrepancy affects spinal posture. Although, several studies evaluated the relation between spinal alignment, spinal configuration and primary dysmenorrhea, but, there is no previous study investigate the effect of leg length discrepancy on primary dysmenorrhea. So, this study will correlate leg length discrepancy with spinal configuration and primary dysmenorrhea.
Statement of the problem:
Is there an impact of spinal posture on primary dysmenorrhea in girls?
Hypothesis:
Null hypothesis: There is no impact of spinal mobility ,spinal configurations and leg length discrepancy on primary dysmenorrhea
Detailed Description
Primary dysmenorrhea is defined as painful menses in women with a normal pelvic anatomy. Adolescent girls tend to have a higher prevalence of primary dysmenorrhoea than older women, as primary dysmenorrhoea can improve with age.Asymmetry in upright posture is associated with various outcomes, such as the decreased loading of the affected side in stroke; degenerative changes of the hip, knee, and ankle joints and spine; or a leg length discrepancy.restriction of movement of the lumbosacral vertebrae, body fluid increases within the pelvis as well as contraction of the uterus leading to the intensification of the menstrual pain. Although, several studies evaluated the relation between spinal alignment, spinal configuration and primary dysmenorrhea, but, there is no previous study investigate the effect of leg length discrepancy on primary dysmenorrhea. So, this study will correlate leg length discrepancy with spinal configuration and primary dysmenorrhea.
One handred healthy girls with regular menstrual cycle and are not have any pelvic or gynecological disorders will be participated in this study. All subjects will be recruited from student of faculty of physical therapy, Cairo University.
- Personal data: All data will be recorded in a recording data sheet.
- Formetric Raster stereography: It will be used to assess spinal configuration (kyphotic angle, lordotic angle, pelvic inclination, trunk inclination and pelvic tilting) during menstruation.
- Leg length discrepancy Tape measure can be used to measure the true leg length from the anterior superior iliac spine to the medial malleolus. The functional leg length is measured from the umbilicus to medial malleolus.
- Inclinometer can be used to measure range of motion of lumbar spines.

Outcomes
Primary Outcomes
lateral deviation
Time Frame: 1 month
the total deviation of the spinal midline from the VP-DM line in the frontal plane , i.e the maximum deflection on the right plus the maximum deflection on the left
lordotic angle
Time Frame: 1 month
this is the maximum lordotic angle measured between the surface tangents of the thoracic-lumbar inflection point ITL and the lower lumbar-sacral inflection point ILS
Trunk inclination
Time Frame: 1month
the trunk inclination refer to the difference in height between VP and DM based on a vertical plane (sagital section). an angle \>2.8 referred to as " Inclination" (I), an angle \<2.8 as "reclination" (R).
Kyphotic angle
Time Frame: 1 month
this is the maximum kyphotic angle measured between the surface tangents of the upper inflection point ICT in the vicinity of the VP and the thoracic lumbar inflection point ITL.
pelvic inclination
Time Frame: 1 month
this is calculated as the mean torsion of the DLand DR surface normals
pelvic tilt
Time Frame: 1 month
the difference in height of the lumbar dimples, based on a horizontal plane (transverse section ). DR is higher than DL if the angle is positive
pelvic torsion
Time Frame: 1 month
pelvic torsion is calculated from the reciprocal torsion of the surface normals on the two lumbar dimples (vertical components). If the difference angle is positive, then the normal on the right dimple (DR) is up more than on the left dimple.
Secondary Outcomes
- leg lenght discripancy(1 months)
