Summary

This study looked at how sitting in a regular chair versus an ergonomic chair changes the curve of your lower back and pelvis. Researchers measured 20 people, some with chronic back pain and some without, to see if chair type makes a difference. The goal was to understand how sitting posture affects back pain, not to test a treatment.
