Effects Of A Hip Orthosis On Lumbopelvic Coordination In Individuals With And Without Low Back Pain, Colin Drury
Effects Of A Hip Orthosis On Lumbopelvic Coordination In Individuals With And Without Low Back Pain, Colin Drury
Theses and Dissertations--Biomedical Engineering
Individuals with low back pain (LBP) demonstrate an abnormal lumbopelvic coordination compared to back-healthy individuals. This abnormal coordination presents itself as a reduction in lumbar contribution and an increase in pelvic contribution to trunk motion. This study investigated the ability of a hip orthosis to correct such an abnormal lumbo-pelvic coordination by restricting pelvic rotation and, as a result, increasing lumbar contributions. The effects of the hip orthosis on the magnitude and timing characteristics of lumbopelvic coordination were investigated in 20 patients with LBP and 20 asymptomatic controls. The orthosis significantly increased lumbar contributions by 11%, 5.42%, 4.84%, and 4.89% …
