Abstract:

Statement of Significance: Musculoskeletal biomechanics are an essential component for optimal sports performance.1,2,3 Lacrosse is a technical sport that requires precise biomechanics for players to effectively shoot the bal.4,5 Prior studies suggest improved biomechanics of the hips and spine contributing to improved outcomes for major lacrosse actions. 6,7,8,9,10 Osteopathic Manipulative Treatment (OMT) has been shown to improve many different components of biomechanics.11,12, 13,14 To Evaluate the Effect of Osteopathic Manipulative Treatment (OMT) and key biomechanics contributing to lacrosse shot power and accuracy. Research Methods: This prospective interventional study recruited participants from the Salt Lake Storm, a Men’s Senior-A Box Lacrosse Team in the Box Lacrosse League (BLL). Players were instructed of the risks and benefits of OMT and given the option to participate. Players who elected to participate in the study were anonymously assigned a number to collect their lacrosse shot performance statistics. 13 players elected to participate in the study. Players were evaluated for lacrosse shot speed and accuracy. Speed was evaluated by giving the players two attempts at a high velocity lacrosse shot and the highest miles per hour (MPH) was recorded. Accuracy was evaluated by players shooting 10 yards (9.144 meters) from the goal. Accuracy was assessed by the proportion of the 5 shots that hit the 20.5” by 20.5” by 30” target. Once baseline shot data was recorded, players were treated utilizing osteopathic techniques including muscle energy, high-velocity low-amplitude, counterstrain, and Still’s technique. OMT was limited to the pelvis, sacrum, and lumbar regions. Shot accuracy and speed were re-evaluated using the same methodology as baseline data collection. A paired, two-tailed t-test was used to compare the quantitative results of accuracy and speed before and after OMT. Data Analysis: A total of 13 players participated in the study. All participants were adults that identified as male. A paired, two-tailed t-test resulted in a mean accuracy difference of a marginal improvement of 0.08 (p=0.829, 95% CI –0.68 - 0.84) and a slight mean speed increase of 0.23 MPH (p=0.804, 95% CI –1.75 - 2.21). Conclusion: Based on the results of the study, OMT focused on the lumbar and pelvis regions has failed to demonstrate a statistically significant benefit on shot accuracy or throwing power in a Men’s Senior-A Box Lacrosse Team in the Box Lacrosse League. However, these findings can be of use to researchers investigating OMT’s effect on sports performance by either improving upon the limitations that are inherent for this study’s design or investigating other body regions to optimize the biomechanics of athletes. Additional studies can give further insight to the potential benefit of OMT to athletes and help promote athlete performance.
