Previous studies have shown a link between spine and lower limb movement. The link between modified pelvic and lower limb range of motion (ROM) and LBP may vary by gender. Therefore, the purpose of this study was to explore gender differences in pelvic and lower limb kinematics during walking in people with chronic low back pain. Participants included 20 individuals with chronic LBP (10 males). Pelvic and lower limb kinematics was tracked using a seven-camera motion capture system. Oneway ANOVA was conducted to compare the range of motion of pelvis, hip, knee and ankle joints during walking between males and females. Male group showed less pelvic (P= 0/02) and ankle (P= 0/03) ROM in sagittal plane compared to female. Additionally, male displayed more ankle ROM in transverse plane (P= 0/01) in comparison with female. Males with LBP displayed less motion in the sagittal plane and more motion in the transverse plane in the dominant limb in comparison with females. Therefore, gender specific design of interventions for pelvic and lower limb should be considered to improve CLBP.
