Abstract
  • Objective: To determine what effect lacrosse helmet fit (properly fit helmet, competition fit helmet, and helmet removed) has on movement of the cervical spine during a prone log roll. Subjects: Eighteen varsity male lacrosse players at The University of North Carolina at Chapel Hill. Methods: Head-to-thorax and helmet-to-thorax movement in the frontal, sagittal and transverse planes were recorded during a prone log roll for each helmet fit condition. Motion data was integrated and normalized to measure the total amount of sagittal, transverse, and frontal plane movement. A series of repeated measures ANOVA's were used for statistical analysis. Results: There was a significant difference in the amount of head-to-thorax movement that occurred in the transverse plane (F2,34 = 6.00, p = .006). Pair wise comparisons determined the transverse plane motion to be significantly greater in the properly fit helmet condition than in the helmet removed condition (Mean Difference = 5.19, Std. Error = 1.21, p = .001). A significant difference in the amount of movement between the head and helmet were found in transverse planes of the competition fit (F1,17 = .11.211, p = .004) and properly fit (F1,17 = 22.005, p Discussion: The results of this study suggest that the presence of the Cascade Pro7 lacrosse helmet only causes head movement to increases in the transverse plane when the helmet is properly fit. Because the helmet is difficult to remove when the athlete is prone and most lacrosse helmets are improperly fit, it may best to leave the helmet in place until the athlete has been log rolled.
