Research Centre: Royal North Shore Hospital
Location: Reserve Rd, St Leonards NSW 2065, Australia
Lead Researchers: Professor Jonathan Morris,  Dr. Sean Seeho
HREC Committee: This study has been reviewed and approved by the Human Research Ethics Committee of Northern Sydney Local Health District 2020/ETH00916


According to Sleep, a good night’s sleep is essential for both the mother and the baby’s health. During pregnancy, the mother can experience a wide range of challenges, like nausea, heartburn, backache, and night sweats, that make sleep difficult. The need for pregnant women to find a mattress that could help to relieve or reduce these symptoms can influence the quality of sleep they get.

The purpose of this study is to evaluate the safety and effectiveness of the Belly Bed when used by pregnant women who are in their third trimester and have experienced pain during this pregnancy such as sacroiliac joint pain, lumbar spine pain, and/or symphysis pubic pain. The Belly Bed has not been approved by the Therapeutic Goods Administration (TGA) as a treatment for pregnancy-related pain in Australia. However, the device has been on the commercial market as a potential device to help provide pregnancy-related pain relief. 

Interested participants must be pregnant women who are 18 years old and above. Participants must be willing to comply with all the study requirements for over approximately 3 months.
