Static and dynamic postural control in competitive athletes after anterior cruciate ligament reconstruction and controls

Purpose To evaluate the test–retest reliability and compare the static and dynamic postural control values in competitive athletes following anterior cruciate ligament (ACL) reconstruction and controls. Methods Thirty athletes, 8.4 ± 1.8 months after ACL reconstruction, and thirty healthy matched co...

Description
Summary:Purpose To evaluate the test–retest reliability and compare the static and dynamic postural control values in competitive athletes following anterior cruciate ligament (ACL) reconstruction and controls. Methods Thirty athletes, 8.4 ± 1.8 months after ACL reconstruction, and thirty healthy matched controls were asked to execute single-leg stance and single-legged drop jump tests onto a force plate. Amplitude and velocity in anteroposterior and mediolateral directions, and mean total velocity were measured for static evaluation. Peak vertical ground reaction force (PVGRF) during landing and takeoff and loading rate were measured for dynamic evaluation. To evaluate test–retest reliability, 15 participants of each group repeated the tests 6–8 days after the first session. Mixed model of analysis of variance was used to determine differences between the involved, uninvolved, and control limbs. The test–retest reliability was measured using intraclass correlation coefficient and standard error of measurement. Results Greater postural sway has been observed in the operated leg of ACL-reconstructed athletes compared with the non-operated side ( P
