The Effect of a Cognitive Task on Lower Extremity Biomechanics and Performance during Landing Elizabeth Meyer, Yvonne Sciascia, Ross Cook, Taylour Hinshaw, Chaoyi Wang, Qin Zhu, and Boyi Dai

Overview Background on ACL injuries The current study History and prevalence The current study Methods Results/discussion Future directions for research

Severity and Prevalence of ACL Injury ACL injuries represent about 3% of all athletic injuries (Hootman & Agel, 2007) Approximately 200,000 injuries annually (Dai et al., 2012). 70% are non-contact (Boden, et al., 2000) Women more susceptible Incomplete recovery from surgical intervention (Busfield et al., 2009) Only 44% of athletes return to competitive sport (Ardern et al., 2011) Only 63% return to pre-injury functioning Focus needs to be on prevention

Mechanisms of Non-Contact ACL Injury Large forces on the knee load the ACL Initial Knee Flexion Knee Valgus Peak Vertical Ground Reaction Force b-reddy.org www.oandp.org

Effect of Cognitive Tasks Research suggests: Injured athletes typically demonstrate unbalanced posture at time of landing (Krosshaug, et al., 2007) Cognitive tasks alter landing biomechanics and performance (Stephenson, 2015). Sports are dynamic environments Athletes are required to react to stimuli Gettyimages.com

The Current Study Purpose: to examine the effect of a secondary cognitive task on lower extremity biomechanics and performance during a jump-landing task. Hypothesis: Subjects will land with: Decreased knee flexion Increased vertical ground reaction force Decreased jump height Increased stance time

Subjects 26 total subjects: 17M, 9F Age: 21.6 ± 1.3 years Height: 1.78 ± 8.7 m Mass: 75.6 ± 13.0 kg Inclusion criteria Exclusion Criteria Retro-reflective marker placement

Testing Procedure Standardized warm-up Jump a distance equal to one half body height Immediately perform a countermovement jump for max height Three conditions No cognitive task Count backwards by 1 Count backwards by 7

Data Analysis Variables analyzed Statistical Analysis Knee flexion angle at initial contact Total knee ROM during first landing Peak VGRF during first 100ms Jump height Stance time (time between initial contact and vertical jump) Statistical Analysis Paired T-test Type I error rate set at 0.05 for statistical analysis

Results

Discussion and Future Research The addition of a cognitive task CAN alter jumping mechanics and performance Decreased performance Increased risk for ACL injury Future directions for research Incorporate more sport-specific cognitive tasks Lab settings may not be representative of actual injury risk – incorporate cognitive component
