Pelvic girdle pain and relevance of ASLR testing: A ... - Cindy Verheul

Following test combinations are compared with the Levene's test for Equality of Variances
and t-test for Equality of means. Here we have following findings:
o Test 1: group of women who scored negative at the ASLR test in combination with a
positive score on one or more of the other tests for pelvic instability is compared with the
group of women who have negative scores on the ASLR test as well on the other tests
used for the pelvic instability. The results of this comparison are not significant. See table
7 for the group statistics and table 8 (appendix ) for the independent sample test.
