Trunk muscle morphology and lumbopelvic stability in adolescent soccer players with unilateral lumbar spondylolysis: a cross-sectional study.

ABSTRACT:

Background

Lumbar spondylolysis (LS) is a common cause of low back injury in adolescent athletes; however, little is known about the relationship between trunk muscle morphology, lumbopelvic control, and LS. This study aimed to clarify trunk muscle morphology and clinical test characteristics in adolescent male soccer players with unilateral lumbar spondylolysis (uni-LS).

Methods

In total, 19 of the 107 adolescent male soccer players were enrolled and categorized into a uni-LS group, based on magnetic resonance imaging (MRI), and an age-, height-, and weight-matched control group. MRI-derived cross-sectional areas (CSAs) of the L4/5 vertebrae were extracted, and the psoas major (PM), multifidus (MF), and erector spinae (ES) muscles were analyzed. Active straight leg raise (A
