Abstract

The aim of this study was to investigate the effect of lumbopelvic control (LPC) weakness on the symmetry of foot pressure distribution, vertical ground reaction force (GRF) and postural sways of athletes with frequent landings. In this case-control study, 34 professional players participated. LPC was assessed by Knee Lift Abdominal, Bent Knee Fall Out, Active Straight Leg Raising, and PRONE tests by Pressure Biofeedback Unit. Based on the results, participants were divided into two groups: appropriate LPC (n=17) and poor LPC (n=17). Foot pressure data were collected using PT-scan. The results showed that there was a significant difference between the mean scores of the foot pressure distribution symmetry, depth force, second peak force, area of sways, anterior-posterior and medial-lateral sways. Thus, poor LPC affects the symmetry of the foot pressure, GRF, and the postural sways of athletes with frequent landings, so can be a risk factor for lower limb injuries.
