abstract = {Injury from blunt head impacts causes acute neurological deficits and may lead to chronic neurodegeneration. A head impact detection device can serve both as a research tool for studying head injury mechanisms and a clinical tool for real-time trauma screening. The simplest approach is an acceleration thresholding algorithm, which may falsely detect high-acceleration spurious events such as manual manipulation of the device. We designed a head impact detection system that distinguishes head impacts from nonimpacts through two subsystems. First, we use infrared proximity sensing to determine if the mouthguard is worn on the teeth to filter out all off-teeth events. Second, on-teeth, nonimpact events are rejected using a support vector machine classifier trained on frequency domain features of linear acceleration and rotational velocity. The remaining events are classified as head impacts. In a controlled laboratory evaluation, the present system performed substantially better than a 10-g acceleration threshold in head impact detection (98% sensitivity, 99.99% specificity, 99% accuracy, and 99.98% precision, compared to 92% sensitivity, 58% specificity, 65% accuracy, and 37% precision). Once adapted for field deployment by training and validation with field data, this system has the potential to effectively detect head trauma in sports, military service, and other high-risk activities.},

The questionnaire was administered twice, once before a custom-made MG was prepared and again after it was used. The replies to being asked whether or not they were dissatisfied with wearing the MG showed that the number of players who were dissatisfied decreased after using the custom-made MG. There was no dental trauma with either MG, but non-dental trauma in the oral area and cerebral concussions were both less frequent with the custom-made MG. We think that to improve the frequency of MG use, it is necessary to eliminate the dissatisfaction with wearing them and increase their usefulness. We also think that using MGs with superior fit and wearing comfort that can be worn throughout the entire game will be effective in preventing trauma and cerebral concussions. ABSTRACT FROM AUTHOR},

abstract = {The players in the 85th Japan High School Rugby Football Tournament were required to wear a mouthguard following enactment of a domestic law for the game in Japan in December 2005. In this article, we report the results of the questionnaire survey to the players. The all players according to the survey the 79.8% of the players had already worn a mouthguard before the enactment of the law. On the contrary, the all players ware a mouthguard in this tournament. In the investigation of the same tournament 9 years ago, the prevalence of wearing a mouthguard was 44.4%. Mouthguards have now become very popular for high school players in Japan. Tooth injuries were reported in 34 players (2.7%) compared with in 81 players (6.4%) 9 years ago. 75.7% of the players had their mouthguards custom-made at a dental office. The International Rugby Board (IRB) recommends the use of a mouthguard to protect against not only injuries of the teeth but also concussion. The IRB asks players to wear a mouthguard that has been properly designed and fabricated. We propose that mouthguards should be made according to standards for the materials, design, and fabrication.
