4.2.1. Pain provocation SIJ tests
Laslett’s test series
In order to match the inclusion
criteria, three out of six
provocation SIJ tests had to be
positive. Nine women tested
positive on the left SIJ and ten
on the right SIJ; accordingly,
five women tested positive on
both SIJs (see graph 4A). The

treatments showed positive results in only nine test persons. Only two of the women
were SIJ positive on both sides. Five women showed such a high degree of physical
improvement that they no longer matched the inclusion criteria for SIJ instability.
Based on the number of positive
provocation SIJ tests it was
possible to identify a more affected
side and a less affected side in the
test persons. In case of an identical
result on both sides, the results of
the sacral shear, ASLR and Faber
tests were also consulted.
On average, the number of positive

provocation SIJ tests on the more affected side (MAS) decreased from a mean of
3.93 tests before the three osteopathic treatments to a mean of 2.36 tests after the
treatments. On the less affected side (LAS), the number of positive tests decreased
from a mean of 1.93 tests to a mean of 1.00 tests. (see graph 4B)
