Abstract

Introduction: Marching band performers are susceptible to a variety of injuries that may have long-term consequences, especially in the lower extremity. The Star Excursion Balance Test (SEBT) dynamic stability assessment tool has been utilized to detect the risk of lower extremity injuries, such as chronic ankle instability. The SEBT may be influenced by internal and external load variations amongst individuals; however, the interactions between these factors and the impact on specific populations, such as marching band performers, have not been studied. Therefore, the purpose of this study is to determine how performance on the SEBT differs when taking external load from instruments and body composition into account in marching band performers. Methods: Height, weight, leg length, and body composition via DEXA Scan were obtained during each initial visit. During the second visit, the subject completed the SEBT with and without carrying various musical instruments bilaterally. Results: There were 31 participants in the study, 3 participated solely in the body composition portion of the study, 1 only participated on the SEBT, and 27 participated in the entire study. The participant's age (19.67±1.74 years), height (169.72±10.46 cm), weight (81.73±19.96 kg), total mass (80.75±20.51 kg), fat mass (29.59±12.47 kg), lean mass (48.58±10.50 kg), fat-free mass (51.16±10.95 kg), bone mineral density (1.23±0.12 g/cm2), bone mineral content (2.58±0.49 kg), and relative skeletal muscle mass (7.62±1.46 kg/m2) were all measured. Total mass had the most amount of significant correlation with lower reach scores. The tenor drums were found to significantly lower reach distances compared to all other conditions in each reach direction and stance limb (p≤0.05). There were no significant symmetrical differences in reach scores when loaded (p≥0.05). Conclusion: Wearing the tenor drum significantly decreases performance on the SEBT. Future investigations should look at the prevalence of lower extremity injuries in tenor drum players in relation to the SEBT to help determine at-risk performers. External load did not reveal significant asymmetrical differences in reach scores when compared to unloaded scores. All variables of body composition, especially total mass, have correlations with lower reach scores.
