Low Back Pain Reduces the Amount of Lumbopelvic Movement During Lower Limb Motion: A Cross-Sectional Study of Soccer Players

Soccer players with LBP demonstrate reduced lumbopelvic movement, particularly in rotation, under low-speed conditions. This may reflect a motor control strategy to avoid pain by limiting lumbopelvic movement. However, no significant differences were observed under high-speed conditions, possibly because high-velocity tasks require greater lumbopelvic movement, making it difficult to restrict movement even in the presence of pain. Rapid lower limb motions, such as kicking or sprinting, may involve greater lumbopelvic movement. Consequently, training and rehabilitation programs for soccer players with LBP should consider the potential for symptom aggravation under high-speed conditions.
