ClinConnect Summary

This clinical trial is studying whether the DaSuit® cushion can help reduce discomfort for adults who have low back pain that gets worse when sitting. The researchers want to find out if this special cushion spreads pressure more evenly under the sitting bones, improves how the spine lines up, and if it’s safe and comfortable to use. To do this, participants will sit on both the DaSuit® cushion and a regular cushion that looks the same but doesn’t have any special features, to compare the effects.

Adults between 20 and 50 years old who have mild to moderate low back pain related to sitting, are of average height and weight, and have a small pelvic height difference when sitting might be eligible. During the study, participants will sit on a chair with each cushion for about 10 minutes while their posture is carefully controlled, watch a short video, and have their spine X-rayed after each session. They will also be asked to share any discomfort or pain they feel. This study is not yet recruiting, but it aims to better understand if the DaSuit® cushion could be a helpful and safe option for people with sitting-related back pain.
