ObjectiveThe purpose of this study was to evaluate time, head movement, and ratings of satisfaction with several popular tools used for retracting a football helmet face mask.Design And SettingSubjects retracted the face mask using a Phillips screwdriver, a Trainer's Angel, and an anvil pruner. A utility knife had to be eliminated from the study after the first two subjects were injured.SubjectsFive certified athletic trainers, five emergency medical technicians, and five student athletic trainers retracted a face mask with each tool.MeasurementsTime was measured by stopwatch and movement by a force platform. Efficiency was calculated from total time and radial area. Ratings of satisfaction were reported by the subjects.ResultsThere was no difference in the total time to retract the face mask using the three tools. Movement was significantly (p < .05) greater with the Trainer's Angel than with the anvil pruner or screwdriver. Subjects were more satisfied with the anvil pruner than the Trainer's Angel or screwdriver. When grouped by the subjects' credentials, there were no differences in time or rating of satisfaction among the certified athletic trainers, emergency medical technicians, or student athletic trainers, but there was a difference for movement. The student athletic trainers produced the least movement and the certified athletic trainers produced the most.ConclusionsIt is suggested that the skill of face mask retraction be learned and practiced.
