Effects of Pelvic Clock vs Pelvic Tilt Exercises on Pregnant Women with Low Back Pain during Their Third Trimester

Purpose: To evaluate the effect of pelvic clock exercises compared to pelvic tilt exercises in pregnant women with low back pain during their third trimester.Methods: A randomized clinical trial registered in the Iranian Registry of Clinical Trials (IRCT20210730052018N1) was conducted with 26 pregnant women allocated into two groups.Both groups received hot pack treatment for 10 minutes.Group A performed pelvic clock exercises, while Group B performed pelvic tilt exercises, five sessions per week for four weeks.Pain and functional disability were assessed using the Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI), respectively.Normality of data was confirmed using the Shapiro-Wilk test (p > 0.05).Paired t-tests were applied for within-group comparisons, and independent sample t-tests were used for betweengroup analyses.Results: Both groups demonstrated statistically significant improvements in pain and functional disability (p < 0.05).However, participants performing pelvic clock exercises showed greater improvements compared to those performing pelvic tilt exercises.Conclusion: Pelvic clock exercises are more effective than pelvic tilt exercises in reducing low back pain and improving functional ability among pregnant women during their third trimester.
