DO PEOPLE WITH UNILATERAL CAM FAI FAVOUR THEIR SYMPTOMATIC LEG DURING MAXIMAL DEPTH SQUATS?

##article.abstract##

Cam Femoroacetabular Impingement (FAI) is caused by an abnormally convex femoral head-neck junction and can damage the peripheral acetabulum in activities requiring a large hip range of motion (ROM). This study analyzed the three-dimensional (3D) ground reaction forces (GRF) and moments (GRM) and the resultant GRF of the symptomatic and asymptomatic legs in participants with unilateral cam FAI during a maximal depth squat. Seventeen participants with unilateral cam FAI performed 5 maximal depth squats with each leg on a separate forceplate. No significant differences were found between the two legs. These results indicate that participants with cam FAI do not favour their affected leg during maximal depth squats.
