- The incidence of injuries to the oral and maxillofacial region during judo competitions has been found to exceed 80%, and the use of sports mouthguards (SMGs) is expected to reduce the incidence of injuries among Players. However, rules of the lnternational Judo Federation prohibit the use of SMGs. To promote the use of SMGs among judo competitors, we aimed to examine the activity and role of the stomatognathic system during judo competitions. We investigated the occlusal contact and muscle activity while performing judo techniques by simultaneously measuring dynamic occlusal contact areas, occlusal force distribution, and electromyography. We used a custom-made sensor sheet(FPD-T-Sports) to measure occlusal contact, and measured the muscle activity of masseter, temporalis, and digastric muscles on the dominant side of the body. Before the measurements, the subjects were instructed to clench and open their mouths maximally, and the means of the maximum values for occlusal contact force and area as well as electromyographic envelope were considered 100% for the individual. Throws and breakfalls were selected from among the basic judo movements as the test movements during free practice, and groundwork techniques were selected from among the movements during actual contests. Occlusal contact during judo varied among the subjects, and contact was seen beyond the area found in maximum clenching. Although the myoelectric potential in the test muscles increased during practice compared with that before practice, the amount of test muscle activity and occlusal contact did not reach the values found in maximum clenching in any of the subjects. Moreover, increases in digastric muscle potential were found, indicating that maximum clenching was not performed. As the stomatognathic system activity during judo varies according to the athlete, only SMGs that are custom-made for individual athletes are recommended.2013
