“…That said, a study has reported that the measurement of body sway during early childhood often reflects concentration rather than standing stability 8) due to the difficulty of remaining stationary during measurement. Attentional functions are closely related to concentration.…”

We focused on the relationship between body sway patterns and motor and attentional functions in early childhood, and classified diagrams of body sway into four patterns. Furthermore, the relationship between physical fitness tests and Interactive Metronome (IM) tasks was used to determine whether the body sway patterns are indicators of motor and attentional functions in early childhood. [Participants and Methods] Participants were 24 male and 26 female children with a mean age of 2,148.1 ± 103.7 days. Participants were evaluated using physical fitness tests, body sway measures, baseline scores on the IM task (the "task average"), and the percentage of perfect hits ("Super Right On") on the IM task (the "Super Right On" score, or SRO%). [Results] The association between the body sway pattern and motor and attentional functions was examined, and results revealed that the body sway pattern was only slightly associated with motor functions. However, participants with an anterior-posterior pattern of body sway had worse timing and attentional functions than participants with other patterns, as indicated by a lower task average and SRO% on the IM task. [Conclusion] These results suggested that anterior-posterior sway may reflect attentional functions when body sway is measured in children such as 6 year-olds.

The aim of this study was to clarify the effect on the postural control function of equalizing the occlusal contact state by wearing a mouthguard. Method: Participants included 23 untrained adults, 11 gymnasts, and 10 weightlifters. Custom mouthguards were fabricated and adjusted so that all teeth were in even contact with light clenching. The standing postural control function was evaluated by the displacement of the center of foot pressure (COP) measured using a gravity center fluctuation meter. Measurement conditions were with and without a mouthguard. Statistical analyses were performed on the differences in COP displacement among participant groups and between mouthguard conditions and the difference in the reduction rate of COP displacement when wearing a mouthguard among participant groups. Results: COP significantly decreased in the order of untrained adults to weightlifters to gymnasts, irrespective of the mouthguard condition. The reduction rate in COP displacement after wearing a mouthguard was greatest in gymnasts. Conclusions: The effect of the mouthguard on postural control function was more pronounced in gymnasts than in untrained adults and weightlifters, and this study suggests that equalization of the occlusal state by wearing a mouthguard contributes to improving postural control function.
