Abstract

Context: Participation in athletic teams and events can lead to injury. As the difficulty in stunts and acrobatic maneuvers increase so does the risk for injury. With this emerging sport and the skills needed to participate, it is important to identify those athletes at risk. Yet, it is unknown whether a functional screening or proprioceptive tool can be used to predict injury in this population. Objective: The purpose of this study sought to determine if compensatory movement patterns predispose acrobatics and tumbling athletes to injury, and to determine if a functional movement screening (FMS) and Lower Quarter Y Balance Test (LQ-YBT) could predict potential injury risk in the sport population. Design: This is a prospective exploratory study to screen for potential injury in the sport of acrobatics and tumbling. Setting: The testing took place in an axillary space at a DII University. Only one clinician administered the testing. Patients and Other Participants: A total of 22 participants (age 19.25yrs +/- 0.91, height 161.97 +/-7.03cm, weight 62.53 +/- 8.71kg) from an acrobatics and tumbling team were used in the study. All participants volunteered for the study, were current student-athletes at a NCAA DII institution with a physical on file and participants on a NCATA recognized Acrobatics and Tumbling team. Intervention: Scores on the FMS and LQ-YBT were calculated for NCATA Division II acrobatic and tumbling student-athletes at the start of the competitive season. The participants were asked to complete the seven movement patterns and three clearing tests of the FMS along with the LQ-YBT test in three directions. The participants were given a total of three practice trials for each test. Screening data was gathered over a two week period at the beginning of the season. Results. The mean FMS score and standard deviation for all subjects was 15.9 +/-1.87 (maximum score 21). The mean and standard deviation for all subjects were 98.36 +/-11.63 for the right and 99.24 +/-12.01 for the left. Cox Snell R2 was used to determine the percentage of the variables used to fit the model. Years of competition and total accounted injury produced a Cox Snell R 2 (0.276) and OR= 1.451 (CI95=0.980 to 2.149) for years of competition. FMS Final, LQYBT (R) and LQYBT (L): Cox Snell R2 (0.259), FMS Final not significant (P=0.36) OR= 1.983 (CI95=1.045 to 3.763). FMS Cut (≤14, ≤15) and total accounted injury: Cox Snell R2 (0.342) and significant (P=0.028) OR 28.335 (CI95=1.429 to 561.997) for FMS Cut (≤14, ≤15). Conclusion: Compensatory fundamental movement patterns, increased skill and years of competition can increase the risk of injury in acrobatics and tumbling athletes. A score of 14 or less on the FMS tool paired with a higher number of previous injury resulted in a 28-fold increase in risk of injury in collegiate acrobatics and tumbling athletes.
