J Athl Train. 1997 Jul;32(3):211-5.
The 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.
Subjects 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.
Five certified athletic trainers, five emergency medical technicians, and five student athletic trainers retracted a face mask with each tool.
Time 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.
There 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.
It is suggested that the skill of face mask retraction be learned and practiced.
本研究旨在评估几种常用的橄榄球头盔面罩回卷工具的耗时、头部运动情况和使用者满意度。
受试者使用 Phillips 螺丝刀、 Trainer's Angel 和 anvil pruner 回卷面罩。在最初的两名受试者受伤后，Utility Knife 被从研究中剔除。
五名认证运动训练师、五名急救医疗技术员和五名学生运动训练师使用每种工具回卷面罩。
使用秒表测量时间，使用力平台测量运动。效率通过总时间和辐射面积计算得出。受试者报告满意度评分。
使用三种工具回卷面罩的总时间没有差异。使用 Trainer's Angel 的运动幅度明显（p <.05）大于 anvil pruner 或螺丝刀。相对于 Trainer's Angel 或螺丝刀，受试者对 anvil pruner 的满意度更高。按受试者资质分组，认证运动训练师、急救医疗技术员和学生运动训练师在时间或满意度评分方面没有差异，但在运动方面存在差异。学生运动训练师的运动幅度最小，认证运动训练师的运动幅度最大。
建议学习和练习面罩回卷技能。
