Pregnant individuals also commonly experience low back and/or pelvic girdle pain. Other populations with pain, such as older adults with back pain demonstrate increased fall risk. This study assessed the relationship between standing balance control characteristics during single leg stance and low back/pelvic girdle pain scores during and after pregnancy with eyes open and closed.
