The hypothesis was that women with pelvic girdle pain (PGP) would lack a feedforward mechanism in the pelvic floor muscles (PFM) in relation to a functional instability problem. Eight women with PGP and 10 pain-free women were included. A clinical examination was performed to verify that participants with PGP fulfilled the diagnostic criteria used in this study. Surface electromyographic activity was recorded from the PFM and unilaterally from abdominal muscles and the rectus femoris muscle. Participants performed leg lifts (performed as Active Straight Leg Raise (ASLR) tests), first with one leg and then with the other. The lift was also performed with an extra weight strapped on one leg. Median onset of PFM activity occurred before the initiation of the lifts in both groups. One woman experienced more severe PGP/dysfunction demonstrated by a higher score on the ASLR test during the clinical examination. This woman presented onset of PFM activity after the initiation of the lifts. The findings suggest that a feed-forward response of the PFM is present during leg lifts in women with and without postpartum PGP. However, one can speculate that a lack of feed-forward in the PFM may be associated with a load transfer problem.
