Objectives: The aim of this study was the analysis of activity of selected muscles stabilizing the sacroiliac joints in pregnant women suffering from pelvic pain and changes in the pattern in response to the implementation of Kinesio Taping (elastic tape).
Material and methods: Seventeen women with Pregnancy-related Pelvic Girdle Pain and 20 pregnant women without pain in the lumbar-pelvic complex were enrolled into the study. In patients with pelvic pain, the parameters describing the action of the muscles were assessed: before the tape was applied, immediately after application, 3 days into application and 5 days after the cessation of taping. In the control group, the test was carried out one time. The activity of the muscles was measured during extension of the hip from a four-point kneeling position.
Results: The gluteus maximus muscle shows higher resting activity values than in the control group, before and after application of the tape as well as five days after the removal of the tape. Before application, the gluteus maximus activates quicker than in the control group while the ipsilateral extensor spinae had a delayed activation when compared to the control group.
Conclusions: The patterns of activation of tested muscles and their action potential values are different in the group of women with pelvic pain compared to the group without pelvic pain. The application of KT in the lumbar region appears to alter the activation of the GM muscle as well as improve activation of IES muscle during hip extension from the four-point-kneeling position.
