The Effects of Balanced Seating Pressure on Pelvic Asymmetry: A Pilot Study
Sponsor: Chang Gung Memorial Hospital
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

Interventions
Dasuit Cusion
The Dasuit cushion is placed on a 40X40X40 wooden box as a chair, and the pressure seating mat is placed on the cushion. Participants were asked to sit on the cushion with hips, knees, and ankles positioned at approximately 90° angles at ease. A tablet was mounted in front of the chair at 30-40 cm from the eyes and at a downward viewing angle of 5-10 degrees. Participants were instructed to watch a 10-minute video to maintain a fixed gaze and minimize head movement. The patient was to sit on the cushion at ease for 1 minute to adjust to the cushion, then under-buttock pressure was recorded for 10 mins.
Placebo
The placebo cushion is placed on a 40X40X40 wooden box as a chair, and the pressure seating mat is placed on the cushion. Participants were asked to sit on the cushion with hips, knees, and ankles positioned at approximately 90° angles at ease. A tablet was mounted in front of the chair at 30-40 cm from the eyes and at a downward viewing angle of 5-10 degrees. Participants were instructed to watch a 10-minute video to maintain a fixed gaze and minimize head movement. The patient was to sit on the cushion at ease for 1 minute to adjust to the cushion, then under-buttock pressure was recorded for 10 mins.
Washout
A 10 min washout period is in between the two interventions. The paitent is asked to walk around at ease.
