Relationship between lower extremity injury experience and dynamic balance function in school-age female badminton players

PurposeLower extremity sports injuries are associated with impaired dynamic balance function, and the modified Star Excursion Balance Test (mSEBT) is proposed as a screening tool for lower extremity injuries. This study aimed to clarify the relationship between dynamic balance function and lower limb injury experience among school-age female badminton players.MethodsForty-two subjects were included. The mSEBT was used for dynamic balance function evaluation. Furthermore, lower limb joint range of motion, lower limb muscle strength, and foot arch height ratio were measured. Lower limb injury experience within the past year was assessed using a questionnaire. The subjects were divided into the injury and non-injury groups according to lower limb injury experience, and mSEBT and physical function results were compared. Multiple regression analysis was conducted with the mSEBT value as the dependent variable and previous lower limb injury experience as the independent variable, with the knee extension muscle strength, arch height ratio, and age as covariates.ResultsIntergroup comparison showed that the injury group had significantly higher mSEBT and dorsiflexion angle values and lower arch height ratios. No significant differences were found for the other parameters. In the multiple regression analysis, mSEBT had a significant relationship with previous lower limb injury experience.ConclusionsA high mSEBT score was significantly related to previous lower limb injury experience. Further research is needed to examine this difference, including external factors such as training intensity and frequency, as well as physical function factors.
