Pelvic belts and pillows
There was low-quality evidence from one trial (Kalus 2007; N = 94 analysed) that there was no significant difference between the BellyBra’sandtheTubigrip’sabilitytorelievepain(meandifference (MD) -0.20; 95% CI -1.19 to 0.79) or to increase the women’s ability to perform activities of daily living (MD -0.90; 95% CI - 1.81 to 0.01; Analysis 3.1; Summary of findings 3).
There was very low-quality evidence from one trial (serious study design limitations, sparse data) that the Ozzlo pillow (a specially- designed pillow) placed under the pregnant abdomen relieved night-time pain better than a regular pillow in the same position. When using the Ozzlo pillow (Thomas 1989; N = 92 analysed), women reported significantly lower intensity of backache at night and during the day, but no significant difference in their abilityto sleep through the night. The women’s impressions were that the Ozzlo pillow was at least moderately more effective than a regular pillow for preventing or relieving theirback pain and at leastmod- erately more valuable for supporting them while sleeping.These results should be regarded with caution since the estimate of effect was measured for all women who used each pillow, rather than comparing each phase of this cross-over trial independently.
