Landing Technique and Ankle-dorsiflexion Range of Motion are not Associated with the History of Lower Limb Injuries among Youth Basketball Athletes

Abstract

Background Lower limb injuries generate a significant health burden in basketball. Landing technique and ankle-dorsiflexion range of motion have been suggested as risk factors for lower limb injuries among youth athletes, but studies conducted specifically with basketball athletes are lacking. Hypothesis/Purpose To describe the period prevalence of basketball-related injuries and to examine the association of the history of lower limb injuries with landing technique and ankle-dorsiflexion range of motion asymmetry among youth basketball athletes. Study Design Cross-Sectional Survey. Methods Youth basketball athletes were asked to complete a paper-based survey to investigate personal characteristics, training characteristics and their three-month history of basketball-related injuries. The Landing Error Scoring System and the Weight-Bearing Lunge Test were used to evaluate landing technique and ankle-dorsiflexion range of motion. Binary logistic regression was utilized to examine the association of the investigated variables with the presence of history of lower limb injuries among the athletes. Results A total of 534 athletes participated. The three-month prevalence of basketball-related injuries was 23.2% (95% CI 19.7 – 27), and the majority of the reported injuries affected the lower limbs (69.7%; n=110). Sprains were the most frequent type of injury (29.1%; n=46), and the ankle (30.4%; n=48) and knee (21.5%; n=34) were the most affected anatomic locations. Landing technique (p = 0.105) and ankle-dorsiflexion range of motion asymmetry (p = 0.529) were not associated with the history of lower limb injuries. Conclusion The three-month prevalence of basketball-related injuries was 23.2%. Although ankle sprains were the most frequent injury, landing technique and ankle-dorsiflexion range of motion asymmetry were not associated with the history of lower limb injuries among youth basketball athletes.
