3.4.3. Palpation
The sensitivity to pressure of the following six anatomical structures was assessed by
means of palpation, classifying them as tender or normal.
Hansen et al. in 1999 [16] and Wormslev et al. in 1994 [71] conducted studies to test
these structures in pregnant women, too. I also took the results from these studies
into consideration.
PSIS
Since the mobility of the SIJ increases during pregnancy, the joint capsule and the
adjoining ligaments get increasingly irritated. [39]
70 % of the 220 persons tested by Hansen et al. [16] showed tenderness to palpation
of the PSIS.
Pubic symphysis
Since the mobility of the symphysis increases during pregnancy, the joint capsule
and the adjoining ligaments get increasingly irritated. [39]
80 % of the 227 persons tested by Hansen et al. [16] showed tenderness to palpation
of the pubic symphysis. Wormslev et al.’s test of this structure in 40 pregnant women
indicates a reliability of kappa=0.55. [71]
Iliopsoas muscle
69 % of the 227 persons tested by Hansen et al. [16] showed tenderness to palpation
of the iliopsoas muscle.
Wormslev et al.’s test of this structure in 40 pregnant women indicates a reliability of
kappa=0.40. [71]
