pelvic asymmetry of their parents?

Asymmetry within the pelvic structure can lead to a cas-
cade of postural compensations throughout the spine,
predisposing people to recurrent somatic dysfunction
and decreased functionality. As a basic structural ele-
ment, the pelvis should be fully symmetric with respect
to the sagittal plane. However, many studies conducted
by different researchers showed, that the asymmetry of
the pelvis is a very common case. This asymmetry was
recorded as a result of various types of measurements
made on the basis of X-rays, TK as well as sectional
preparations. The reason for this was seen in the shor-
tened one of the lower limbs or the lumbar spine
The aim of this paper is to answer the question: If
there is any relationship between pelvic asymmetry in
children and pelvic asymmetry of their parents?
Material and methods
A total of 180 volunteer subjects were included in the
study and classified into 60 groups. Each group included
one child (aged 3-17 years, 30 males and 30 females)

and its biological parents; mothers aged 29 to 50 and
fathers aged 30 to 52. To determine the asymmetry of
the pelvis, each person was tested in the same manner.
The palpation examination of anatomical landmarks
(the highest points of iliac crest) has been carried out in
a symmetrical prone position of the tested one.
Approved measurement accuracy was 0.5 centimeters.
Type of asymmetry marked as the term, which iliac
crest was more distant from the investigator. Method of
the study is shown in a Figure 1.
The results of measurements of pelvic symmetry are
presented in Tables 1 and 2.
The carried out research shows that there is a relation-
ship between the laying of the pelvic bones of the child
and mother. Correlation of the measured displacement
is significant and amounts to 0.65. In terms of type of
asymmetry is a very strong correlation and its value is
equal to 0.93. The compound of symmetry of the pelvis
of the child and father is negligible. Although the corre-
lation is negative (respectively - 0.24 and - 0.34, inverse
correlation), the strength of this correlation is small and
irrelevant. The results encourage further exploration.
The problem is still open.
