The Effects of Balanced Seating Pressure on Pelvic Asymmetry: A Pilot Study
Taiwan20 participantsStarted 2025-09-12
Plain-language summary
The goal of this clinical trial is to learn if the DaSuit® cushion helps reduce discomfort caused by sitting in adults with non-specific low back pain. It will also assess the safety and physical effects of using the DaSuit® cushion. The main questions it aims to answer are:
1. Does the DaSuit® cushion distribute the pressure evenly on both under-buttock pressure compared to a placebo cushion?
2. Does the DaSuit® cushion improve spinal alignment compared to a placebo cushion?
3. What discomfort or adverse events do participants experience when using the DaSuit® cushion?
Researchers will compare the DaSuit® cushion to a placebo cushion (a look-alike cushion without therapeutic effect) to see if the DaSuit® cushion works to relieve sitting-induced discomfort.
Participants will:
1. Use the DaSuit® cushion or a placebo cushion in a randomized order, with each sitting session lasting 10 minutes
2. Complete both conditions with a 10-minute washout period between sessions
3. Sit on a standardized wooden chair with a pressure sensor mat placed on the cushion surface
4. Keep a fixed posture with hips, knees, and ankles at approximately 90 degrees
5. Watch a 10-minute video on a tablet positioned 30-40 cm in front of them at a 5-10 degree downward angle to maintain a steady gaze
6. Undergo spinal imaging immediately after each session, maintaining the same seated posture
7. Report any discomfort or pain experienced during or after each session

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
